There's mixed views about running 18 or 19s for track work and indeed all rears (square set-up). Certainly you will get more life from tyres as you can rotate your wheels from front to back when they wear.

My 18s follow the BMW staggered set-up and hence the rears are wider than the front. I think in general you want to aim to keep the offsets very close to the OEM offset figures - whether by having custom made hubs or by using wheel spacers to have the desired effect.

My wheels/tyres are:

Front 18x9.5J ET+41 (265/35/18 tyre)
Rear 18x10.5J ET+28 (285/30/18 tyre)

(FYI, standard OEM 19" offsets are Front ET+44, Rear ET+27 iirc)

There's a few threads on here about 18" wheels. Here's some:
