hi, i hv a 2007 R56 Cooper S and would like to know whether Rota Slipstream 17 rims can fit ApRACING BBK " CP6638 Calipers with 330 Disc" ? I m now running with JCW R105 18" rims and would like to change to Rota 17". The BBK will arrive 2 months later. Any suggestions ? One more question, which size, offset should i order ? 17x7.5 or 17x8 ? +45 or others ?

Cheers


Ernie
