I just picked up some new wheels. Got some Giovanna Kilis 20x8.5 with a 38 offset. My car is lowered approx 1.5" with the SR springs. The wheels are still slightly tucked in the wheel well, especially the fronts.

What size spacers would I need to get the wheels flush? AM has a few different spacers. I think 1" may be too much. Maybe 1/2" would do. I don't want the wheels to stick out andspray rocks all over the side of my car .

I am running 255/35 tires too.

 

Measure it yourself with a ruler. We can tell you whatever, but you should know your car best, and buy accordingly. And if the measurement is .75", but you have a choice of 1.0" or .5" spacers, then get the .5" spacers, I'd say.

Be sure to get new, longer studs to accomodate the spacer, and also ensure there's not going to be any interference with the new location. Fenders and tires do not mix well...
