Hey Razy.. thanks for the update.. Guess that makes you our official tester... 
$1500 doesn't sound like a lot to invest for those sort of results... Does that include the better brake pads...?
Edit: Bit of a Q car.. doesn't look like it's modified except for the roll cage (from outside...)
The brake pads are extra, but I would not recommend them for daily driving, they are very noisy and would wear out very quickly if used at cold temperatures (which is what you normally do on the road). Ferrodo makes a more user friendly compound, the DS2500, which I think would be best for road use and also much cheaper than the DS3000R.
The exterior is very much like a standard i30 apart from the ride height which is about 40mm lower (due to the springs and tyres). I don't think this would be an issue unless you plan to take it on really rough roads, but then you wouldn't want harder suspension anyway.
