STR40/38-44/32

The StopTech 2-Piece AeroRotor and Hat Slotted Rotor; Front Driver Side delivers enhanced braking efficiency by reducing unsprung and rotational mass while improving thermal capabilities. It is designed to optimize heat dissipation and maintain compatibility with original equipment calipers, making it an essential upgrade for performance-driven vehicles. This rotor assembly features aircraft-grade aluminum hats paired with a precision-machined cast iron friction ring that is slotted and cross-drilled for superior cooling and brake pad bite. The rotor’s vented design with proprietary internal vanes enhances heat dissipation, and the non-coated finish keeps the rotor functional and ready for high-performance use. Installation is straightforward with a direct bolt-on design requiring no additional drilling or modifications. The floating disc mounting system facilitates improved rotor alignment and longevity while maintaining ease of service.
