I am looking into a new wheel set up and I have read trough many of the threads on here and I think the following set up will work. These are made to order and I want to make sure they will fit prior to ordering.

1989 Iroc Stock Height and Suspensing

Wheel: Intro Apache
Front Set Up - 18x9.5, 5.5BS, 275/35/18, Bolt Pattern 5x4.75
Rear Set Up - 18x10, 6BS, 285/35/18, Bolt Pattern 5x4.75

 

Looks good to me.

 

You are going out of your way to have a set that cannot be rotated. Just go all 9.5 / 275.

 

I appreciate the response, now my next concern is the wheel bore and dust cap clearances.

 

I am not to concerned about rotating the wheels. I actually have never rotated the wheels on the original Iroc rims, since the only way to do so would be to dismount the tires given that factory Irocs are designated as rears and fronts. I am going for the widest possible wheels out back.
