Product Details
Forged from aluminum, the caliper bodies in this Brembo big brake kit are built to handle the extreme heat and stress of track use. This kit is specifically designed for the Subaru WRX STi, offering a significant upgrade over the factory braking system. The 6-piston configuration works with the large 355x35mm 2-piece rotors to provide more clamping force and better heat dissipation, which is crucial for maintaining consistent stopping power during demanding driving conditions.
The 2-piece rotor design features a floating hat, allowing the rotor ring to expand and contract freely with temperature changes. This helps prevent rotor warping and cracking, extending the life of the components. The T3 slotting pattern on the rotor surface is a popular choice for race applications, as it helps to keep the pads clean and degassed, ensuring optimal contact and improved braking performance. The black anodized finish on the caliper bodies not only looks sharp but also adds a layer of durability.
This kit is a comprehensive solution for WRX STi owners looking to significantly improve their vehicle's braking capabilities for track days or spirited driving. It includes everything needed to install the front big brake kit, ensuring a direct fit for the intended application. Remember to consult the manufacturer's installation guide for specific details regarding brake fluid type and bleeding procedures.
