Yeah the 2mm difference would be unnoticeable. Most of the time wheel manufacturers have 2 or 3 face designs and then obtain all the necessary offsets simply by machining (or casting/forging) the hub to suit. So in that case they would almost certainly look exactly the same.
Cheers, the TE37 are still very tempting as well.
Might make a phone call and depending on who has the Rota's in stock see if i can't arrange a test fit to decide between them... then comes the question of color as always. :lol:
I've done the whole dark on dark thing before, this time I think a little contrast is in order hence the white as a possibility!
