Brembo 1JD.9027A3 GT Series Big Brake Kit

The Brembo 1JD.9027A3 is a GT Series Big Brake Kit engineered for performance drivers who demand superior stopping power on both the street and track. Drawing on Brembo's decades of motorsport expertise, this complete brake upgrade system delivers dramatically increased thermal capacity, fade resistance, and pedal feel compared to factory brake setups.

At the core of the kit are aluminum calipers with opposed pistons, engineered to act on the brake pads with greater precision. The smaller individual piston diameters reduce pressure per piston while the increased overall pad-to-piston contact surface promotes more uniform friction material wear. Caliper stiffness combined with included metal-braided brake hoses minimizes fluid absorption, resulting in a firmer, more consistent and controllable brake pedal.

The kit features Brembo's signature 2-piece floating disc design with an aluminum alloy hat. This construction reduces unsprung mass for improved handling dynamics while also minimizing thermal stress. The floating mounting system allows greater radial and axial movement, which together with the enlarged rotor surface area, significantly improves heat dissipation during repeated hard braking — maintaining consistent performance lap after lap.
