Not my S4 but my brothers, however, he wants to start tracking his car, while I do track mine which is track prepped ISF, he wants another set of wheels for the track and what options he has.

I'm running on Enkei's FP01's, they're light wheels and has lots of options, I checked Tirerack and didn't see that wheel available for Audi or maybe it's no longer available, however, there was RPF01 which is even lighter than PF01, what I'm unsure about is:
1) What offset I should get?
2) What width? I think I saw 9.5 fit the S4 but would like confirmation, would 10.0 fit?
3) What is the max tire-width I can put on 9.5w without rubbing and no spacers.
4) As far as Tire options, he'll probably start with Max or Ultra Summer, let them be chatty before he moves to R'comps;

Thanks in advance.

I see this Forum gets a little to no replies, is there any other forum I can go that might answer my questions and is more active?

Have you tried the AudiWorld Wheels & Tires Discussion thread at https://www.audiworld.com/forums/whe...-discussion-2/ ?
Alternatively you can try Audizine. There's a Wheel & Tire Tech forum, a Wheel Fitment Discussion sticky, an S4 forum and other stuff.
