nice one thanks lads, I have read that boxster fronts have 28mm wide discs and our 312mm discs are only 25mm wide so wont that be a problem. I couldn't find a definate answer and because the lcr has brembos as standard I thought it would all fit. If I get 312 black diamond discs then the unswept area should still be covered in black so shouldn't be an mot faliure I hope. Also what pads are used with boxster fronts and 312 discs. I have read the definitive brake guide but not too much info on brembos. Thanks for the answers.
