If you want a little wider finding the S rims which are 9 wide rears would allow you to run 265's. The other 17s will bump you up one class and you will be less competitive.

Extra tips.

Run M030 ROW with stock front plate and stock springs, camber plates will bump you to the next class. The springs are a gray zone because they weren't official original parts, but are still available through porsche.

Don't get a seat, that bumps you to the next class. Get 6 point harness and run stock seats.

If you are not worried to compete in a higher class (STX, i think its that, basically facing against S2000s.) Use the 8.5 and 9 rims with a square tire setup. (same tire front back this allows you to run the RS4s ) Get a seat and 6 point harness, we have an incorporated roll bar which makes it easy to setup. M030 row as you planned with camber plates and maybe larger bars. I would do rear first for AutoX or Front first for track.

Have fun.
Thanks for the info.

In my case, I am running PCA, not SCCA, so much of the class issues you mentioned don't apply. We have a point system for performance mods and tire width. What size wheel makes no difference

My questions pertain to the handling of the car not the class it will run in

In any case, good info. Thanks
