Brembo 00-02 S4/02-05 A4/06-08 A4 Front GT BBK 4 Piston Cast 365x29 2pc Rotor Drilled-Red

The 365x29mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its excellent thermal properties and durability under heavy braking. This kit is designed to significantly upgrade the stopping performance of your Audi S4 (2000-2002) or A4 (2002-2005, 2006-2008). The larger rotor surface area and the robust four-piston calipers work together to dissipate heat more effectively and apply more consistent clamping force, which translates to improved fade resistance and shorter stopping distances, especially during spirited driving or track use.

Brembo's GT Big Brake Kits are a popular choice for enthusiasts looking to enhance their vehicle's braking system beyond factory specifications. The calipers are forged for strength and feature a red finish for a distinct look behind the wheels. The two-piece rotor design, with its floating hat, allows for thermal expansion without inducing stress into the rotor itself, further contributing to consistent performance and longevity. The rotors are drilled, which helps to vent gases and moisture away from the pad surface, maintaining optimal friction even under demanding conditions. This kit includes everything needed for installation, providing a comprehensive solution for a substantial brake upgrade.

When installing a big brake kit like this, it's important to ensure you have adequate clearance within your wheels for the larger calipers and rotors. Refer to the manufacturer's installation guide for specific fitment details and any recommendations regarding brake fluid types. A proper bedding-in procedure is also crucial to achieve the best performance from the new pads and rotors.
