Brembo 1N3.9550A5 GT Series Front Big Brake Kit 405x34mm 6-Piston Yellow Caliper

The Brembo 1N3.9550A5 Gran Turismo (GT) Series Front Big Brake Kit is a complete, bolt-on high-performance braking upgrade featuring a 6-piston monobloc cast caliper finished in Brembo's signature yellow and a 405mm x 34mm two-piece Type 3 slotted rotor. Engineered for drivers who demand race-inspired stopping power on the street and occasional track use, this system delivers a dramatic improvement in braking performance, thermal capacity, and pedal feel over the factory setup.
