Autocrosscooper's brake lines will match up to the caliper and the firewall w/o modifications. I was running EBC Red Pads on my R56S stock fronts and liked them a lot! I changed to Brembo calipers (Got em for $600) and was not able to source EBC Red Stuff for the Newer R56 Brembos (Not in production yet). I went with Carbotech 1521's. They don't stop as well as the Red Stuffs but they produce a lot less dust than the Red Stuff's. For what its worth...
Yeah the bobcats were WAAAAY too much to justify the expense especially with making the purchase of everything else that was needed. Maybe if I ever get to the track enough were I need race pads then I'll switch over to carbotech but for now hopefully the EBC's will perform well.
