Product Details
This is the Brembo 1T1.9020A5 Front GT Big Brake Kit, specifically designed for the 2019 and newer BMW Z4 and the 2020 and newer Toyota Supra. This kit replaces your factory front braking components with a high-performance setup, featuring a 6-piston caliper and a substantial 380x34mm two-piece rotor. It’s built to handle the demands of spirited driving and track use, offering a significant improvement in stopping power and heat management over stock brakes.
The heart of this kit is the Brembo GT caliper, cast from durable aluminum for a strong yet lightweight housing. It utilizes six pistons, which distribute clamping force evenly across the large, 380x34mm two-piece rotor. These rotors are drilled, a design that helps dissipate heat and expel gases and water from the braking surface, leading to more consistent performance, especially under heavy braking conditions. The two-piece rotor construction allows for better thermal management as the aluminum hat can dissipate heat independently from the iron friction ring. This kit is finished in a striking yellow caliper color, adding a visual upgrade to your vehicle's appearance.
When installing this kit, you'll be replacing your entire front brake assembly, including the calipers, rotors, and mounting brackets. It's recommended to consult the manufacturer's installation guide for specific procedures and torque specifications. Because this is a significant upgrade, it's also a good idea to consider upgrading your brake fluid to a higher temperature rating and potentially stainless steel brake lines to get the most out of the new hardware. This kit is a substantial investment in your vehicle's performance and safety, offering Brembo's renowned engineering and braking technology.
