Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed specifically for the Toyota MR2, providing a direct replacement that meets OEM specifications. The solid rotor construction offers durability while the cross-drilled holes and slots improve brake pad bite and help evacuate gases, dust, and water from the rotor surface. This design reduces brake fade during aggressive driving or track use. The coated hat finish protects against corrosion, extending rotor life. With an overall height of 1.575 inches (40 mm) and a center hole diameter of 2.126 inches (54 mm), these rotors fit precisely on the MR2’s hub assembly. The floating disc mounting and two miscellaneous holes contribute to proper rotor alignment and heat management.
