As someone that has owned my share of M cars, I guess I'll chime in.

One of the simplest things to do to any BMW with floating calipers is to go to a brass bushing and toss the rubber. The bushings eliminate to torquing of the calipers and allows an even bite across the pad. When the rubber caliper bushings wear, they allow way to much flex.

A BBK works fine if you plan to track a car. On the street it's bling factor and that's about it. Braking performance is measured in how fast you can dump heat as it builds up, clamping force, and swept area.

There are people that switch to floating rotors and upgrade the guides on factory calipers and get good pads and do perfectly acceptable track days.

Quite frankly, I think the "M" brand was tainted after the e30 M3 (Flame suit on). It was a purpose built car for European Touring Car. It was hand assembled and they on made about 14K units worldwide. That WAS and M-Car just about everything since has been a poser.

Anyway, I like the e9x M3, but I bought a 335i Sedan.
Where can I get some bling brakes???? 8-)
