355x35mm Front Big Brake Kit

The StopTech 83.160.4C00 is a front big brake kit engineered to provide superior street performance and a significant upgrade over stock braking systems. This kit includes 2-piece sport rotors, measuring 355 x 35 mm, designed with a slotted disc style for improved heat dissipation and consistent performance. Equipped with ST40 4-piston calipers, this big brake kit (BBK) is built to increase heat capacity and reduce brake system compliance, leading to more responsive and powerful braking. The 2-piece rotor design offers advantages in weight and thermal management. This specific kit is noted as a 'Part Fit Note: 40' and is specifically designed for the BMW M3'08 models with 355x35 rotors and ST40 calipers.
