AC Schnitzer launched a new high performance brake system for all three variants of the current BMW M3. The new brake system uses fixed calipers with 6 pistons on the front and 4 on the rear. The slotted brake discs, vented internally on both front and rear, respond quickly and precisely.
Since weight is important in a sporty, dynamic car such as the M3, AC Schnitzer managed to reduce the weight by 8.8 lbs compared to the standard brake system.

At the same time, the AC Schnitzer high performance brake kit is renowned for its excellent deceleration values even on sustained use, in extreme heat and in pouring rain. The generously sized brake discs measuring 380 x 35 millimeters at the front and 355 x 32 millimeters at the back bleed off the speed energetically and with stable pressure even after the twentieth time.
Auto magazines tested the new high performance brake system and stated that they are “”totally suitable for the track, and for a long time”.
Pricing is unknown at this time, but expect it to be quite costly.

I suppose conditions influence the braking capabilites.
Edmunds Insideline tested the M3 and it got 60 to 0 (100km to 0) in 100 feet, which is about 31 metres.
I wouldn’t get this brake system. For the VERY small improvement in numbers and for the, most likely, very high price point it’s just really not worth it in my eyes.
I agree.
The small improvement is definitely not enough to compensate the prices. I think the reality is that BMW manufactured the M3 as sort of ‘race’ car, therefore giving much attention to details needed for the track such as the brakes. This may be the reason why it is very difficult to improve those numbers by much.
Actually, I believe the brakes probably are less prone to fade, and overheat. AC Schnitzer never go for the numbers, they always use refinement.
LOL…another overpriced aftermarket piece from ACS! So many other options at fractions of the cost, so I suppose there will always be a few who will pay the premium for that nice shiny AC Schnitzer logo on those calipers. Sad really….
