How wide spacers with factory rims?
Best regards Kleiv.
Then I switched to SL55 take-offs wich were 8.5"and 9.5" wide with ET30 F and ET33 R with the same tires, and that was a perfect set up.
Don't put any spacers on the front as 10mm is minimum for a hub-centric machined spacers, and it will make your car look like a dune buggy.
At the Rear, do a compression test with one wheel over a curb, to determine what gap you have left between the tire wall and the rolled fender lip.
Slide an increasing number of credit cards around the tire until you get stuck and that's your gap to play with, just back off 3mm.
