Im ordering a set on 5Zigen 5ZR rims. They are 8.5x20 on the front and 9.5x20 on the rear. What offsets do I need? I want to be able to lower it to without any rubbing and for the wheels to be flush with the arch.

Front is available in +20 and +27
Rear is available in +16 and +21

 

Agressive would be the +20/+21. That would looks sweet, and really fill out the wheels well. +16 in the rear would be out of the question. +27 in the front is acceptable but not as agressive looking as the +20 but both will work. I am not familiar with the wheel and don't know if these sizes will clear the brakes. But if all these sizes clear then I would go with the +20/+21.

Respect
