Rear Inboard Sprint Car Brake Kit

The BREMBO Rear Inboard Sprint Car Brake Kit (part number 7K2.2001A) is a purpose-built braking system engineered for high-performance sprint racing applications. This rear brake kit combines a 4-piston caliper with an 11-inch slotted iron rotor to deliver the thermal management and stopping power required during sustained track operation. The gray anodized aluminum construction reduces unsprung weight while maintaining structural rigidity under the extreme deceleration forces encountered in competition.

The 4-piston caliper design distributes clamping force evenly across the rotor surface, minimizing pad wear variance and extending service life between rebuilds—a critical consideration on sprint cars where downtime directly impacts race schedule. The slotted rotor geometry promotes heat dissipation and helps evacuate gases generated during hard braking, reducing fade when brake temperatures climb into the operational window. Aluminum construction of the caliper body keeps rotating and unsprung mass to a minimum, directly improving suspension compliance and allowing the chassis to work more effectively through technical sections of the track.

This kit is specified for rear brake upgrade applications on sprint cars where factory systems lack adequate thermal capacity or modulation. Teams running intensive practice schedules, heat races, and feature events benefit from the predictable bite and recovery characteristics BREMBO systems are known for in motorsport. The complete kit format eliminates the guesswork of component pairing and ensures caliper, rotor, and mounting geometry work in concert. Weighing 15 pounds, the assembly integrates into existing brake lines and mounting points on compatible sprint platforms.
