Yea the Audi pepperotts do look nice. i was thinking about some but never got round to it,
similar to mine, ive got 15" Ronal turbos on 195/45 and they run fine although my car is slammed and could do with bigger tyres because its too close to the ground, but the wheels never rub,
but id say go 10mm on the rears

Wideeee !
