need help with fitting FR18s simmins wheels on my iroc
Thats right i've finaly decided to get the best wheels on the market. I have an 89 iroc with a 4th gen rear. The rear is sopost to be 4 inches total wider, right know my iroc wheels stick out about 2 inches on each side. I want to put 18x11 on the back. How should i measure for room? I know i can put 17x11 zr-1 wheels on the back without spacers so don't tell me you can't do it. I'am also going to run 18x9.5 up front and they can build them so they bolt on. These are a simmons FR18 3 piece wheel that is built to your specs. I'am also going to get bell teck spindles to drop the front and use my iroc springs. I will post some pics this week of my car.
I'm running 18 by 10s all around on my IROC with a 5" back spacing. I believe the rear spacing on the ZR-1 rims r 6", so if they fit ur car fine stick with that spacing size or use a 7" spacing. As 4 the fronts use 4 1/2" or 5" depending on how u want the rims 2 sit in the wheel wells.
