With consistent track usage, they have a tendency to break pistons. The 6-piston is more show than go, and a lot of guys "upgrade" to larger 335i brakes, despite having less pistons (and not looking as cool.). It's a direct swap, so relatively affordable.

Any info on how they break pistons? I'd assume that's heat related? I'd think fluid and lines could help control temps. I saw that we can swap in non-ceramic pistons from stoptech for about 500, I'd think that would be a great option.

The 335i brakes are bigger, so they stop better (despite only being single piston,) and they're apparently also better at heat dissipation and rarely have issues on track, from what I've read. To keep up with an M2/M2C, that's the way to go, unless you want to shell out for a Big Brake Kit. |

The M-sport 6-pot brakes are fantastic for street use, and are coveted by subaru and 3-series owners alike, because obviously 6 pistons is better than 4 or 2.... but when it comes to the track; it's the size of the disk that matters most. Conversely, if you're building a street car, there's often precisely zero benefit (other than cosmetic) in upgrading to a $6,000+ big brake kit (with wonderful slotted and drilled disks that are far more prone to cracking), since they perform the same or worse on your first stop compared with OEM, but allow track-racers to take the second lap as fast as the first due to the absence of brake fade. |
