Big brake kits

Last year I invested in a brand new Brembo Big Brake Kit for the front of the M. This consisted of 6 pot Brembos, braided lines. adapter brackets, pads and 345 mm discs. This setup is fitted as standard on the new BMW 135i and they call it the Performance Kit and it comes in the funky gold colour. The improvement in performance is amazing. Finally decided to upgrade the rears. This is purely for aesthetics, nothing else really lol. A member on the M3 forum is putting his car back to standard so I wasted no time and sent him the money over as soon as he posted the package up for sale. Porsche Boxster S Brembo calipers, currently painted Porsche GT3 orange. I'll be getting them painted BMW gold to match my fronts. These fit using the standard M3 rear discs. I'll be getting new discs and pads on anyway. Mot is in May and I need a new rear wheel bearing, so will have the calipers fitted at the same time, can't wait :cool:

You should have some nice braking there mike, plus looks way better than having empty looking rims. What size discs do you run with them? The boxster rears are very good been putting them on 850s rear brakes for 4 years on xc90 308mm.

[QUOTE=MIKESC70T5;768628]Standard rear discs are 328mm[/QUOTE] It's a good size, possibly a slightly unswept inner area? Iirc I think they are designed to run on 300mm ish discs. I had some very good results with mine, they worked quite a bit better than 302mm fronts with a decent set up.
