Hi. Im new to the third gen world. Actually new to the gm world. I have a 91 formula and I have been wanting to upgrade my rims and tires for a while. I have been looking at the c4 zr1 wheels 17x9.5 up front and 17x11 in the rear. I was planning on running 275/40s up front and 315/35s in the rear. The front wheels have 56mm offset I believe positive and the rears have 50mm offset positive. My question is what size wheel spacer would I need to fit these with no rubbing problems. I would like to stray away from cutting and hammering if possible. I would also like to try to keep them in the wheel wells as much as possible. Im not planning on lowering the car ever.. any help would be appreciated.

 

bringing back a thread from the dead so I dont get flamed for starting a new one lol.

I'm in the same boat as the guy above, I'm saving up for the same wheels and would love to keep inner fender work to a minimum. I've already got 4 2" adapters, the fronts I know will be fine but it's the rears I'm a little worried about. Any input? Making the wheels sit flush or even stick out past the fenders a tad would be fine with me, they don't need to be tucked.

 

bumpity bump..

Will my 2" adapters in the front be sufficient or do I need to go and invest in some 2.25's?
