BIG BRAKE KIT 2 PIECE ROTOR; FRONT

The StopTech Trophy Sport Big Brake Kit, which includes the 83.658.6D00.63 rotor, is engineered for ultra-high performance street use and occasional track days. Key components include patented StopTech Aero Rotors designed for optimized airflow, and patented, billet 7075 aluminum Aero Hats that further enhance airflow and reduce unsprung weight. The kit incorporates forged StopTech STR 6-piston calipers equipped with a patented bolt-in bridge for superior stiffness and consistent pedal feel. Both the calipers and Aero Hats are finished with a hard-anodized coating to resist fading and discoloration, ensuring long-lasting aesthetics and performance. To complete the system, StopTech stainless steel brake lines and high-performance sport compound pads are included, which are suitable for both aggressive street driving and light track use. The entire kit is meticulously designed to integrate seamlessly with the stock S550 master cylinder and original rear brakes of compatible vehicles, maintaining an optimal brake bias ratio for balanced stopping power.
