The Wilwood 140-13106 ProMatrix Front and Rear Rotor Kit is engineered to deliver measurable braking performance improvements for performance drivers and track enthusiasts who want to retain their OE factory brake calipers. This kit combines two-piece rotor assemblies with lightweight aluminum hats and premium Spec-37 iron rotors to deliver both high-temperature durability on the track and an aggressive, high-tech appearance on the street.

Key Features:

• Two-Piece Rotor Design: Aluminum hat paired with GT 72 and 32 Curved Vane Spec-37 rotor assemblies for reduced unsprung weight and improved heat dissipation
• Spec-37 Proprietary Iron Alloy: Rotors are cast from Wilwood's exclusive iron formulation engineered to resist extreme heat, distortion, warping, cracking, and premature wear
• Military-Derived Technology: The Spec-37 alloy draws from materials and processes used in Wilwood's extreme-duty military-specification rotor program
• OE Caliper Compatible: Designed as a direct-fit upgrade for use with factory brake calipers—no caliper replacement required

• Dual-Purpose Performance: Suitable for high-heat track sessions as well as daily street driving

Wilwood's ProMatrix rotor kits are the ideal upgrade for performance enthusiasts seeking improved brake response, fade resistance, and long-term rotor durability without the cost of a full big brake kit conversion.
