MODIFYING OR DETAILING YOUR I30 => SUSPENSION & STEERING => Topic started by: Doggie 1 on April 14, 2012, 12:57:07

Does anyone know what brand and specification (without being too technical :)) of shock absorbers the i30 uses?
I imagine that they would be built down to a price.
I was wondering whether a worthwhile upgrade might be to fit a set of top quality dampers and if so, what sort of difference would it make to the ride?
I'm not into lowering cars, driving like I'm on a track, etc, but would appreciate some more comfort a more compliant ride.
I'm feeling that my ride is a little harsh and I'm wondering if that might be a legacy of the kms it's done?
-
The SLX ride is fairly firm .. Why not take it to peddars and a few other Suspension places and get some quotes and see what they say .. A 5 page report on here with photos etc.. should suffice :whistler:

That's a good idea - I might do that.
I've always found that anything that comes out of Pedders tends to ride like a billy cart (although perhaps I'm being a little harsh :whistler:) but I do wonder what could be done.
I don't know what the life of a set of original equipment shocks would be likely to be. My car looks like it sits a little low at the back to me.
Although, after its last service I took it to check my tyres and no wonder it was a hard ride - they'd put 42psi all round and I never run them that high.
-
New shocks will give a firmer ride than "old" ones so as the car gets older the ride should soften if anything. Ride height is a function of the springs so "sitting lower" will not be the shocks either.
-
Ok, thanks. I'll have to re-look at it.

:whsaid:
-
Perhaps I should go in and see if they've got any really old ones then that have done 400,000 kms :lol:
I thought that maybe the ride could be improved by fitting better quality ones.
Anyhow, I know it's not as late as in the east, but it's late enough and I'm off to bed me thinks.
-
The ride will soften with old shockers but you'll be bouncing all over the road....lol.
Better quality shocks would no doubt be worth buying....I betcha they won't be cheap though.
Anyhow, it time for bed here too..... :D
Sweetdreams Dave......
-
Don't bother going to Pedders, you'll come out with a list of just about every suspension part needing to be replaced....Probably about 2-3k worth of work....
Seems if its a little dirty, it needs to be replaced.....

Hehehe, my daughter found that out...... :D
-
Thanks, that's pretty much what I've heard. Plus the initial fee to examine the car in the first place whereas most will do it for free.
-
Got them to look at the wife's car.
They quoted nearly 4k, and missed one of the things that was causing the problem.
On the plus side, they said the shocks my mechanic wanted to replace were fine, so in the end, saved me money.
-
the oz delivered i30's have a different strut/shocker set up for our crap road conditions. :winker: they may be of a better quality than we think. :idea: but i don't know what brand they are. :-[
when it comes to buying suspension parts from pedders I've found them excellent for race cars and new cars. :mrgreen: but when it comes to taking an old car there,bring along your check book. :Shocked:

But how old is Dave's car. The Oz Suspension Upgrade" didn't happen from day one as I understand it. Maybe that's the issue.
Many years ago when I was managing a GY store and my Datto rally car was out the front, Brian Pedder came calling with my State Manager. he asked what struts I had and I told him Fulcrum Suspension had given me some Tokiko inserts which were pretty good. Oh. He says, I'll send you up a set of ours to try. They're much better.
Never arrived.
My State manager was already supporting me with tyres and asked later if they came. He was even less impressed than I was.
Having said that we have good business dealings with a pedders franchisee who has a couple of Brisbane stores.

I thought that the suspension upgrade was on the i45 and that the i30 was constant the whole way through?

Can't be sure. I just seem to remember reading a couple of journo reports when I was looking at buying my i30 where they made the comment about how Hyundai had "addressed" suspension concerns by incorporating improvements suggested by Australian engineers.
-
:rofl: I'm not saying anything because in one short decade I'll be 64 too.
But I guess then Trev will be 74........
And Alan will be... :whistler: Sorry, my calculator just blew up :lol:

in late 08 and in early 09 i read about the suspension changes in the oz i30's. our cars are 2/09 and 4/09 built. :mrgreen:

..in late 08 and in early 09 i read about the suspension changes in the oz i30's. our cars are 2/09 and 4/09 built. :mrgreen:
I have a MY09 built September 08. I have always been disappointed with the rather unnecessary understeer. I'm still wondering whether to import an USA rear bar from their "CW" which is quite a bit thicker than ours. The only thing that stopped me earlier on was my inability to determine whether it would fit the hatch.
-
Here's a review of the i30 from 2007, seems like the tweaks were carried out before the i30 was released in OZ.... :goodjob:
http://www.caradvice.com.au/6719/2008-hyundai-i30-first-steer/ (http://www.caradvice.com.au/6719/2008-hyundai-i30-first-steer/)
Suspension has been tweaked by a world renowned handling and ride guru, who carried out substantial testing on Australian roads which I’ve been reminded, are far worse than the UK’s much criticised “B” roads.

AHAA!!!
Old but still remembering things accurately. :goodjob2:

It's the short-term memory that goes first. :whistler:

OK.
All jokes aside, here's the story on shock absorbers.
They lose their effectiveness progressively from day one but the process is such that most people don't notice it until well down the track. But if your vehicle has 100,000 klms on it you can be sure the effectiveness of your shocks is degraded enough to put you at risk in an emergency braking or swerving situation where it is imperative that you maintain your tyre's footprint firmly in contact with the road.
So,in Dave's case I expect ther is a harshness and some extra bounce in the ride which could be described in the way he says.
Fitting new shocks will return the suspension to what it is supposed to be, absorbing unnecessary upward and sownward movement withou too much effect on the car's stability, as well as making the passengers more comfortable.
Last year one of our stores fitted new shocks all round on their Falcon ute with about 120,000 klms on it. I didn't know about it and drove the vehicle one day. I came back to the store and told the manager how impressed I was with the old ute considering the mileage on it. He laughingly explained the situation to me.
Damned thing rides like a sedan, quiet and smooth.
Now, one last thing.
There is only one shockabsorber manufacturer in Australia.
They make their own brand as well as any OE vehicle requirements and any "other ones' marked as made in Australia.
The maker is Monroe and I have been dealing with their products since the 70's and I can't fault them.

Great, thanks Trev, that is great info.

-
Having said all that, I don't know if Monroe make aftermarket units for the i30.
I'll find out tomorrow.
-
Thanks, that would be great.
Would they have different levels of quality too or normally just one model for each make of car?

They do have various levels but I doubt that for the i30.

OK, I'd be interested to see what they have.

Yeah, did that rusty. That's why I said I'd check tomorrow.
I'll talk to Fulcrum Suspensions and to Repco. There will probably be alternatives from overseas, hopefully cheaper than Bilsteins which really are exhorbitant.

Isn't the first listing at the top of that page for a kit to fit coil-overs? Like where it says suspension type: threaded, height adjustable,?

Never tried Boge, but I must say the price seems reasonable and they have a lifetime warranty.... :goodjob:
From what I remember I paid something like that for the Monroe shockies on my old Holden Barina....

Boge do all the self-levelling stuff on Range Rovers and the like.

Boge shocks are fine and if they are actually available the price seems OK.
Monroe do not yet make them. I'm waiting on advice as to whether or not they have them on their radar.
KYB have rears only available for the model from 07 to Feb 09. They have a different listing after that which seems to bear some suuport for the change in suspension somewhere around that time.
Pedders Don't have a listing either but you can bet they will when Monroe does.
In WA, I don't have a lot of contacts but it might be worth talking (in person, not over the phone) with WA Suspensions. I'm told they're pretty competent. They're in Osborne Park.
Not a lot of joy there ATM. :evil:

No worries, thanks Trev, I appreciate it.

Refer the earlier discussion about uprated suspension for Australian i30's after feedback.
Certainly beefed up shocks, and IIRC, a different sized sway bar or bars.
Normally in situations like that they beef up the bushes too.

What different part numbers, Trev?
I have the 2012 KYB catalogue and it only lists the one shock, which shows it suits from March 07 onwards..... :undecided:
Boge don't show anything to support what you're saying either....
I've read other reviews and I'm yet to find any reference to the suspension being updated....
Perhaps you are recalling that in 2009 all i30 hatch models were fitted with ESP Stability Control/Traction Control System as standard? :undecided:
-
I don't necessarily agree, especially given the different part numbers as above.
If the different part no.s are for beefed suspension on later models I wonder if the parts are backward compatible to earlier models, like a superseded part? If so that would be awesome!

Just a harsh ride, thank goodness. Sadly, the car has to go but after 12 years since the mod, it's about right now.

Does anyone know what brand and specification (without being too technical :)) of shock absorbers the i30 uses?
Dunno about OZ, originals for our market are gas type ones, manufactured by KYB. But don't bother because you won't find any as an aftermarket (even from your dealer). I copy from their FAQs:
Q: What is the difference between original equipment KYB and the aftermarket KYB components?
A: Original equipment KYB shock and struts are designed to the OE manufacture’s specifications. Although built on the same assembly lines, the aftermarket KYB products are calibrated to compensate for worn suspension components to help restore the vehicle’s original handling and control characteristics.
KYB aftermarket also offers monotube shocks which for most vehicles will provide additional control and handling capabilities.
Q: Are there any differences between the KYB shocks & struts manufactured in the U.S. vs. other countries (like Japan)?
A: No. All KYB products are designed at the KYB world R&D offices and every KYB manufacturing plant then builds each product to the designed specifications. High volume part numbers are manufactured in more than one plant and in more than one country. Since KYB designs and builds their own manufacturing equipment, we can control and duplicate production specifications which ensures identical performance & quality at every manufacturing facility. Specific product performance is determined by part number, not by where it is manufactured. Product quality is a standard in every KYB part number, in every KYB manufacturing facility.
Anyway, if you insist on KYB, you can find from here it's Excel-G:

My response to this is there'll be no response.
However in respect to readers of the topic, I made my point. Others disagree however i know what I read in 2009 just before I bought my car.
So topic is closed as far as I'm concerned.
I will, however, continue to post any info on shock absorber availability as and when I get it.

It just concerns me that Trev was unsure about these supposed suspension upgrades until 2i30s made mention that he had read in 2008-2009 that the Aussie i30's had upgraded suspension. Steve never said they were upgraded then, just that he had read it then.
Trev seized on that as proof that his memory was right.
Now Trev has said there are different shocker listings for KYB shocks, I have downloaded the latest 2012 catalogue and it shows no such thing. Any i30 review I read makes no mention that the i30 received any suspension upgrades mid life so in the interests of having correct information I was hoping Trev would present his "proof" that what he "recalls" is correct......
The evidence so far seems to point that any suspension upgrades were made before the i30 was launched in OZ. :undecided:
Here's yet more proof.....this review is from October 2007....
http://www.carsales.com.au/reviews/2007/small-passenger/hyundai/i30/hyundai-i30-5252 (http://www.carsales.com.au/reviews/2007/small-passenger/hyundai/i30/hyundai-i30-5252)
The i30 uses conventional coil-spring, MacPherson strut suspension up front, but multilink 'torsion blade' rear suspension like Ford Focus, and better than Toyota's semi-independent set-up for Corolla. Hyundai says the i30's suspension and steering have been optimised for local conditions including thicker sway bars, uprated shock absorbers and revised mapping of the ECU for the car's electric-assisted power steering system.

When I was looking to buy mine in mid 2008 I read that the Oz car had its suspension retuned before release... but it's only my recollection. And in any case I cannot understand why we got a skinnier rear bar than the UK when for me it needs a fatter one than we got.
I'm assuming the UK got the original and we got a smaller one as part of our "tuning". :confused: :confused: Maybe they only tested a petrol version and not the diesel. :undecided:

I'll have to take your word for it, pip...lol.
Actually, I'm surprised you say your i30 understeers so much.....I purposely gave mine a bit of stick coming home this afternoon through some nice bends and thought mine felt fairly neutral. :undecided:

You are obviously a better driver than me... although I have to admit growing up on seriously oversteering cars with live axles that had no chance of hanging on and still think (to a degree) that that is normal.

I'm just saying how my car feels to me and given that we both have pretty much the same car I'm surprised that we see things so differently. :undecided:

How the car actually handles as against its over/understeer setup is I believe somewhat controllable by the driver. I wasn't being facetious. I've only driven FWD cars for last 20 odd years and never came to grips :rolleyes: with the understeer. This car would probably be the worst of them and not helped I imagine by the relatively heavy diesel engine. It relies very much on the tyres to hang on; which they seem to do quite well albeit with lots of noise... all from the front but it does appear to run wide for me. :sweating: I could be doing it all wrong of course. :wacko:
I'm being quite critical here and while the understeer detracts a little for me from the driving experience, overall I couldn't be more pleased with the car. As I once said here... best so far for me. :D
-
What tyres do you have on your car, pip? Mine are Hankook......oh, and you run high tyre pressure like myself, don't you? :undecided:
I've driven quite a few FWD's over the last 20 something years too and I'd say the i30 is one of the better handling cars as far as understeer is concerned, even with the diesel fitted.
My little Holden Barina was a pig with bad understeer which I managed to improve a little by fitting slightly wider tyres.
I browsed a few reviews trying to see what they thought of the diesel's handling and here's what one had to say....
Autospeed 17 February, 2009
The ride is firm and strongly damped – if you’re expecting cushy, luxurious ride quality, you won’t get it. However, the corollary of that is safe, effective handling. The combination of a little understeer and the electronic action of the standard stability control system results in a car that is quick point-to-point but in an unfussed way. However, the outright grip of the Kumho Solus KH15 tyres on 16 inch alloy rims is not great – owners should explore better tyre options when the originals wear out. The power steering – like the suspension, calibrated specifically for Australia – is well-weighted but a little lacking in feel.
-
Same tyres, pressure between 36 and 40 psi depending how often I check. Always pump before a trip.
Did the review say whether the handling notes referred to diesel or petrol? EDIT: I see where you already said diesel :-[
In any case it's quite subjective of course including your and my assessment. I'm only expressing slight disappointment in the "balance" for and aft. The grip is fine and suggests the tyres are held nice and square to the ground. The multilink rear suspension is similar to my last car, along with the front struts and not surprisingly, handling is much the same albeit with a little more body roll - and a little more understeer.
As you probably read in another thread I've been toying with beefing the rear roll bar ever since I got the car. I'm much better at thinking up things to do than actually do so there's a chance I'll just keep talking about it. :wacko: :-[
I think that because for many drivers understeer is easier to cope with than oversteer that it's seen as a sort of primary safety feature and manufacturers either build-in or prefer to leave (too much) inherent understeer in an effort to appear to be safer - or actually safer depending on your point-of-view. ESP/ESC would seem to provide that, and better, layer of safety now so handling could be allowed to be more neutral perhaps?

Ok, so we run much the same tyre pressures then.....
I must admit from your comments re the beefier roll bar I was assuming you thought the handling was downright bad.... :lol:
I think you're right about understeer being probably easier to cope with for many drivers....
Pretty sure when I did the Defensive Driving Course a while back they made reference to this.
Although my little Barina understeered quite badly on sealed roads, it was always the backend that let go first when punting it along on gravel roads....made for some fun driving! :D

Bad news. Monroe don't have shocks/ struts for the i30 in their plans for Australia in the forseeable future.
So. A dead end at least for a year or two it would seem.
Strange though as they have units for the Getz up to (IIRC) 2009.
-
That's just not good enough. :)

I absolutely agree. In retaliation I'm refusing to buy Monroe shocks for my i30.

I was thinking that perhaps I could fly over to the Monroe headquarters to pick up my new shocks but then I'd have to use Qantas so I can't do that, so maybe get them posted over, but they'd need insurance, and I can't do that, but now that Monroe is on the banned list, it solves all my problems. :lol: :goodjob:

i had my wheels off to rotate them and looked for a manufactures name on the struts and shocks,nothing other than made in Korea. :confused: I'm not sure if the strut has a replaceable insert,or the strut is a sealed unit. :wacko: its highly possible that the sway bar diameter and coil spring rates on the oz i30 suspension are the only difference,compared to the UK sold i30. :confused: the more i look into this,the more confused i get. :wacko:
-
It would be really good to know what suspension changes were actually made to (mk 1) Oz cars. So far all I know is that the rear sway bar was reduced from 17mm to 14mm which without knowing what else, seems counter productive WRT greater than desirable understeer (personal opinion).
What else was changed is unknown but I can't believe that this was the only change so conject that the front bar was also lightened (to rebalance the promoted understeer from the skinnier rear bar) and perhaps the spring rates were altered (stiffened) to compensate. :confused:
While not a suspension tuning expert (far from it) if this is even close then the amount of body roll will have increased because stiffer springs are much less effective than roll bars in arresting roll.
Once you accept significant roll then you are also accepting that the wheels will not be held (as) perpendicular to the ground and when push comes to shove something will let go. In a FWD it will be the front that lets go first.
If this is true then I'm not sure what they had in mind because I really think the dynamics are marginal if not downright ordinary, compared to my last car (which was 15 years old) and possibly worse than the original i30 design. :Shocked:
I pose a question: why is the USA car sporting a 21mm rear bar while the Oz car has a 14mm bar? This is a huge difference.
In the absense of other information re what else might (or might not) have been done this alone will significantly reduce understeer and sounds to me like something Oz cars needed. :wacko:
I might offer a possible reason: The USA has grown up with (naturally oversteering) rear wheel drive cars and so strong understeer is simply not acceptable to them. :undecided:

I'm with you here Rusty. As I've said before, my i30 handles as well as my previous car, a Subaru Impreza. Understeer CAN be induced but generally only by approaching the car wrongly. I find the i30 (a Hatch), precise and firm and I really can't fault it. It's true. A stiffer rear bar will reduce the tendency to understeer but I don't feel the need for it.
However, I seem to recall a couple of people on here having fitted heavier rear bars. It might be interesting to hear from them as to the effects.
On the subject of shockabsorbers, I suspect they have been beefed up and that's why Monroe aren't in a hurry to make any. Unlike the Getz with a worldwide market, thay would be having to turn out something just for the Australian cars, thus increasing their costs versus returns.

I really expect the extra weight of the diesel engine has a negative effect WRT understeer. I know Rusty has one but Surfer's is not and as I said before each driver will detect/prefer a different balance anyway.
I can say that as a direct comparison, I've been driving the missus's Getz a lot lately and seriously, it corners much, much better and it's not sporty by any measure. :confused:
-
^^^
You should try my wife's Corolla.
Or the one I test drove before I bought the i30.
I agree the diesel engine is heavier but I'd be interested to hear from some of the other diesel engined drivers.
-
I've never driven a petrol i30 so it's a bit like communism vs democracy, if you haven't experienced both, it's hard to make a fair comparison. Are we absolutely certain that there is no difference in Oz suspension components between petrol / diesel. I'm not a sporty driver but I have no complaints about the handling or understeer of our cars. Living in the hills does give the suspension quite a workout too. :goodjob2: Tomorrow, I'll measure the roll bar to make sure it's 14mm, too cold to do it now. :(
-
both my cars [cw and hatch] are petrol i30s,front and rear bars are the same diameter. :winker:
-
So .... Did anything come up? Wanting to get better outfits for my front and rear, also. Did anyone come across anything better at a reasonable price or not really? :-}

Tires gentlemen. Ditch the Korean donuts and get a decent set of tires. I would bet that the problem substantially then goes away. Cars known for good handling characteristics are not fitted with Korean eco rubber as a rule. Once I need to replace the tires I'll be looking to put on some Michelins and I can't wait. I'll be retiring the pipe and hat at the same time.
On shocks, we used Konis on our Alfas, red (oil) on the 105's, yellow (gas) on the 33's. Konis are adjustable so there's no issue with getting a decent ride. Despite their many alleged flaws, Alfas ride and handle properly out of the box but that's what I put on them nonetheless.
I wonder what our hotrodding Korean cohorts are using?

Sure, information is still valid in terms of improvements over stock as a comparison although I'm guessing Hyundai suspensions might have benefited more from the addition of decent dampers way back then. Had I spent another 30 seconds and gone to the Koni website I might have discovered they don't seem to do them for i30. Cest la vie.
http://www.koni.com/car-racing/finder/ (http://www.koni.com/car-racing/finder/)
Interestingly enough it states this: for original Sachs struts Ø 49 mm only I wonder if the euro built cars have sachs dampers. That's not a bad thing.
I'm still wondering what the hotrodding Koreans use. They would know whats available. And I still think better tires would help more than new dampers.
-
Here you go:
Hyundai, like sister company Kia, undertakes extensive Australian suspension calibration – to the extent of having its own in-house shock absorber dynamometer and getting Sachs shock absorber engineers to wing-in from Germany. And in the testing, winding conditions no doubt both our Hyundai i30 test cars (Elite petrol manual and Premium diesel automatic) were impressive with noticeable firmness in the shock absorber and spring rates for a flat, connected ride (in the European way).

Keith, whilst I agree that putting better tyres on will improve things immensely, I have to point out that, no matter how good the tyre is, unless the suspension is capable of keeping the footprint in optimum contact with the road, the effect will be lost.
So, shocks and springs should be considered in tandem with tyre choices.
-
Agree entirely with that sentiment. I've upgraded shockies and tires on a number of my cars over the years, both road cars and track toys and best bang for buck in my experience for cars where the suspension is in reasonable shape is always tires. Given the snippet regarding the origins of the engineering of the dampers and suspension tuning, I think replacing the Hankook eco rubber with something more salubrious on a new i30 is likely the most cost effective option for improving the handling. Even on cars that do handle well like Peugeots, sticking a decent set of Michelins on them and giving them a proper wheel alignment can transform the handling.
On a car with flogged out suspension, replacing worn components such as shock absorbers and a proper alignment is likely the best remedy - along with some decent tires. :lol:
