Product Details
Brembo is well-known for its high-performance braking systems, and this Rear GT Big Brake Kit (BBK) is a prime example of their expertise. Designed for enthusiasts looking to significantly enhance their vehicle's stopping power, this kit focuses on the rear axle to create a balanced and potent braking setup. It features robust 4-piston calipers paired with substantial 380x28mm two-piece rotors, offering a considerable upgrade over stock components.
The calipers are cast for strength and durability, housing the pistons that apply pressure to the brake pads. These calipers are matched with two-piece rotors, which combine a cast iron braking surface with a lighter aluminum hat. This design helps manage heat more effectively and can reduce unsprung weight. The rotors themselves are slotted with Brembo's Type-1 pattern, which helps to clear away brake dust and gases, ensuring consistent pad contact and improved braking performance, especially under demanding conditions. The yellow finish on the calipers adds a distinct visual appeal to your vehicle's wheel well.
This kit is a comprehensive solution for upgrading your rear brakes. It includes the necessary components to install the larger calipers and rotors, providing a noticeable improvement in braking feel and fade resistance. For optimal performance and safety, it's recommended to consult the manufacturer's installation guide for specific procedures and any additional hardware that may be required for your particular vehicle application.
