If I wanted to push the stance on an r53 with stock s-lites with 205/45's what size spacer would I use. I am running about -2 camber up front and -1.5 in the rear with h-sport springs and koni yellows. Thanks for your help, Walter

 

Whatever fits. Measure the amount of clearance you have and go from there. I am running Koni Yellows with their sport springs for abot -1.5 over stock and run 215/45-17 tires with 5mm spacers. no rubbing

A lot has to do with rim offset

 

I use 5mm spacers with longer bolts. My alignment is the same as yours, but I'm on stock springs and dampeners. I have used 5mm spacers with s-lites, as well as my steel rims and 15" hollies.
