Smallest wheels that fit S4s?

[stapo69]

As it says what's the smallest size wheel diameter wise I can fit over the brakes on my S4, looking at getting a spare set to use on the track.

the 312mm setup JUST fits under 16's, so i'd think the standard S4 17's would be the smallest you'll get on with the standard S4 brakes.

That's what i was thinking, don't think i'd want poop 16s anyways!

I've seen some clips on Youtube of some yank who fits smaller wheels (maybe 15's!) on the rear for drag racing.

Stock rears are only 240 or 256mm depending on year, so i'd imagine 15's would fit over those just fine.
