ZR31 Front Caliper (Street/Track Applications)
ZR31 Caliper Takes Brake Pad Shape 7863
We all know the factory brake system on the majority of BMW models is not great. While okay for street duty, they tend to fall short on track as driver experience levels and speed increase. The single-piston floating calipers simply don't have the heat capacity, pedal feel, firmness, or confidence-inspiring characteristics one needs to turn consistent fast laps on the track.
Enter Performance Friction...
With years in the business of making cars stop faster and more consistently, PFC has developed a close relationship with BMW (and Porsche) and has put a ton of R&D into the development of braking components for BMW vehicles. Along with their class-leading racing pads, PFC has developed several full Track & Race kits. These kits are now standard-issue on many Factory BMW Racecars such as the M235i Racing along with numerous Factory-built Porsche Racecars including GT3R's, 991 Cup Cars, and GT4's. You too can now buy them for your street or track car.
Designed and built without compromise, these kits are the ultimate in braking performance. Made from billet Aluminum, machined into a single piece monoblock caliper making them lighter and stronger than typical cast calipers. These calipers have incredible stiffness, which contributes to pedal feel/firmness.
Don't Have Piston Envy
Sure, 6-piston or even 10-piston brake calipers may look cool, but more pistons don't necessarily equate to more stopping power. A 4-piston caliper will have better release characteristics compared to a similar 6-piston caliper, while also being lighter. PFC calipers are also torque optimized for each vehicle, and generally add a bit more rear bias for improved performance/stability under braking.
If you want to upgrade your track or daily driven BMW's brake system, this is the best brake kit on the market, period.
Calipers are anodized and then powder coated black. Custom colors (blue, red, yellow, etc.) are also available with a 5-8 week lead time.

PFC ZR31 Calipers:
High-Temperature Aluminum Alloy for high stiffness and improved pedal feel at even the highest temperatures.
- High tension seals, for proper piston rollback, reducing drag and improves consistency.
Short Aspect Ratio 4-Piston Design for a stiffer caliper body, reducing drag and temperature as well as improving release and control over 6-piston designs.
- Monobloc-Finite Element Analysis Design reduces caliper deflection for less pedal travel and improved response.
Abutment Design for optimized torque takeout, which improves release and control.
