Anyone think I would run into any issues doing this. Ive heard of people running as much as a 8" rim in the front but Im not sure about the offsets.

I was thinking about buying a set of 4 rear AP1 rims for autocrossing. Im having issues with understeer and thought this would help.

 

The only major issue is that you'll need to bore 2 of the rims so they clear the front hubs.

 

edit: 2

 

The front hubs are bigger than the rears?? Could I just use a small spacer??

 

Yes, and you could probably use a 3-5mm spacer if you don't want to bore the wheels.

 

COOL. That would be better. Would you reccommend longer wheel studs or is 5mm not enough to affect it??

 

You can run a 5mm spacer without changing the studs. That is as wide a spacer that you can run with out changing them.

Atleast that is what I've read on this site.

 

I am going run the same 4 rear AP1, i have heard the that a 5mm spaces is too thick but a 3mm is ok. If i remember the 5mm stopps the lug from seating correctly by 2 twists. i have not tried the 3mm spaces but if you so let us know if it fits

 

5mm works ok on front and you can fit a widenned 8.5" ap1 on the rear with a 5mm as well
use a torque wrench on the lugs

 

Shouldn't you use a larger spacer so the offsets are closer to stock?
