Product Details
If you're looking to significantly improve your BMW M3 or 1M's braking performance, especially for track use or spirited driving, this Brembo Gran Turismo Sport (GTS) Big Brake Kit is a serious upgrade. This kit replaces your factory front brake components with a much larger and more robust system designed to handle extreme heat and repeated hard stops. The larger 365x34mm two-piece rotors offer more surface area for heat dissipation, while the six-piston calipers provide greater clamping force for improved stopping power.
The calipers themselves are cast from aluminum for a good balance of strength and weight, and they feature a durable black finish. The rotors are drilled, which helps to vent gases and moisture away from the pad surface, contributing to consistent braking performance. Being a two-piece design, the rotor and hat are separate, which can help reduce thermal stress and allow for easier rotor replacement down the line. This kit is engineered to be a direct replacement for the factory setup, meaning it bolts on without major modifications, though professional installation is recommended given the complexity of brake system work.
When you're pushing your M3 or 1M hard, having a brake system that can keep up is crucial. This Brembo GTS kit is a well-built solution that offers a substantial increase in braking capability over stock. It's important to note that with any big brake kit, you may need to ensure your current wheels have enough clearance for the larger calipers and rotors; check the specific wheel fitment guide for this kit to confirm compatibility with your wheels. This kit is designed for those who demand the best from their vehicle's braking system.
