Product Details

The Brembo 4K3.8038A PISTA rear big brake kit represents decades of motorsport engineering designed specifically for track use and extreme driving conditions. This complete rear axle kit features Brembo's FF4 4-piston forged calipers paired with 345x28mm Type 3 2-piece floating rotors (54a bell configuration), delivering professional-level braking performance for dedicated track enthusiasts.

Key Features:

  • 4-piston forged caliper with asymmetric body design and fixed tangential bridge for maximum rigidity
  • 345mm diameter x 28mm thick Type 3 2-piece semi-floating rotors with aluminum bell (54a configuration)
  • Lightweight aluminum hat construction reduces unsprung and rotational weight for improved handling
  • Floating rotor hardware allows thermal expansion independent from the bell, preventing distortion
  • Internal brake fluid channels optimized for maximum system bleedability
  • Hard-anodized caliper body for exceptional durability under extreme conditions
  • Complete kit includes calipers, rotors, brackets, stainless steel braided brake lines, and mounting hardware
  • Pre-assembled for easier installation

About Brembo PISTA:

The PISTA series brings over 40 years of racing experience into a comprehensive track-focused brake system. These kits are engineered for drivers who demand the ultimate in stopping power, fade resistance, and consistent pedal feel during sustained high-performance driving. The forged calipers feature the same design philosophy used in top-level motorsports, with structural optimization for strength while minimizing weight. The Type 3 2-piece rotors utilize Brembo's proprietary high-carbon cast iron alloy paired with precision-machined aluminum bells, creating a lightweight assembly with superior thermal management and longevity compared to single-piece designs.

Installation Note: Professional installation is recommended. This is a complete rear axle system that includes all necessary hardware for proper installation.
