I have a 1 and 1/4 spacer on the rear since i think the rear tires even look like they sit to far in. the face of my wheels are flush with they body it looks great and stoped my oversteer. going to a large rim with a shorter sidewall and wider tire was the best thing i've done so far, i hate tire roll

 

Camber bolts for a cheap camber gain.

 

To the OP, are you ready for R-compound tires though? It's much easier to overdrive the car on R-comps, they hide your mistakes more than street tires do. Just throwing that out there.
