Wilwood 140-16530 Promatrix Rear Disc Brake Kit Two-Piece Rotor

The Wilwood 140-16530 Promatrix Rear Rotor Kit is engineered to deliver measurable brake performance improvements for racers and performance enthusiasts while retaining factory OE brake calipers. This race-oriented brake upgrade is designed for drivers seeking enhanced stopping power and thermal management on the track without the complexity of a complete caliper replacement.

Key Features:

• Two-piece rotor design with aluminum hat assembly for superior heat dissipation
• Engineered for high-temperature track durability and consistent performance
• Direct compatibility with OE factory brake calipers for simplified installation
• Optimized for use with high-performance brake pad compounds
• Race-proven design delivering improved braking response and reduced fade

The two-piece construction separates the rotor friction surface from the mounting hat, allowing for thermal expansion without warping while reducing unsprung weight. The aluminum hat assembly provides excellent heat transfer properties, keeping brake temperatures in check during aggressive track sessions. This rear brake kit is ideal for weekend racers, track day enthusiasts, and performance drivers who demand reliable, fade-resistant braking performance.
