Thanks for that reply but like 'Duncan' i'm amazed at how narrow that is (i always thought that they were 17'' so that's good to know). I have seen many vids showing the R32's under race conditions and the wheels look absolutely huge (width wise), There's one shot where the Calsonic R32 cuts the corner too much and both it's wheels lift on this vid http://uk.youtube.com/watch?v=9TT9GpQXug8 (nice vid this!) don't know if i'm looking right but they look more like 255+, any opinions??
