Siko - tell them to stuff it (the Mitsu dealer, that is). A *decent* set of front disks that are comparable/better than the Brembo originals can be had for £250 including VAT. Pads (again, decent stuff) for £200 including VAT for a full set front and rear. That's around £450 *inclusive* for the lot. Piece of #### to fit so do it yourself.
Assess your needs (road/track) and buy from any of the dealers in the MLR mag. (Wastegate Chatter). Save yourself a bomb on main dealer prices and come away with better brakes!
