I just picked up my SP1s.
wheel tire spec;

Front
18x8 +49
225/40/18

rear
18x9.5 +55
255/35/18

I will lower the car sometime next week and am wondering if they will be rubbing
with like 1.8 inch drop on the rear.
i dont want to tuck them in with bad neg. camber tho.
or any chance to roll the fenders?

 

Are you gonna lower with coils or springs? If you use aftermarket springs and stock shocks and lower inch or more your gonna rub.

 

I would not be so sure of that. Different tires have different section widths. So one tire may rub while the next brand does not. The alignment setting will also have a lot to do with it. If you are going to lower the car you would want to run more negative camber.
If I can help let me know.
