VMR is releasing a new CSL-like wheel within the next couple of months. Available sizes are 19x8.5 and 19x9.5. It's cast rather than forged, but VMR claims a 19x8.5 wheel mounted on 245/35/19 General Exclaim UHP weighs 50 lbs., which isn't too bad.

I like the concavity and the overall design myself. Do ya'll have any opinions on how these would look on an E90 M3?
