Hi i30lamb,
I take it the stud pattern is correct .
Hopefully someone will be able to help, if not you gotta do it the hard way.
Is it lowered?
Not much outwards offset, so all the extra will be inboard.
You should use a tape to check , if looks good actually fit them.
From my youth experience,
1) fit the front first and check that you can go form lock to lock with steering.
2) Then go for drive, slowly at first - be prepared for any "bump steering", pick up the pace and find some bumpy stuff to see how it goes.
3) If it goes well put rears on and repeat.
4) Grab 3 or mates and repeat .
AGAIN BEWARE OF BUMP STEER OR REAR LOCKING with extra bodies in car.
The decision will be yours.
I stress Bump Steer.
I once had my front suspension so hard you couldn't move it if 2 people pushed down on it and I thought I had cured my HT Holden of that. (14 × 8 4" offset 235/60 ) Found out that, when on a long curve , in 60k area , doing 140k +, pacing a car alongside of me , that I hadn't.
Thankfully there was nothing in the on-coming lanes and I caught it before going up footpath and into the shops.
