Brembo 18+ X3 /19+ X4 Front GT BBK 6 Piston Cast 380x34 2pc Rotor Slotted Type-1-Red

The 380x34mm, two-piece rotors in this Brembo GT Big Brake Kit are cast from a high-carbon iron alloy, a choice that helps manage heat buildup during aggressive driving. This kit is designed for the front axle of select BMW X3 and X4 models, specifically those from 2018 and later for the X3, and 2019 and later for the X4. It features a six-piston caliper, a significant upgrade over stock, which allows for more pad material to be in contact with the rotor surface. This means better heat dissipation and more consistent stopping power when you need it most.

Each caliper is a monobloc casting, meaning it's machined from a single piece of aluminum. This construction method results in a stronger, stiffer caliper body that flexes less under heavy braking. Less flex means more direct pedal feel and improved control. The rotors themselves are slotted with Brembo's Type-1 pattern, which helps to vent gases and dust away from the pad surface, maintaining optimal friction. The two-piece design allows the rotor to expand and contract with heat independently of the caliper mounting bracket, reducing the risk of rotor warping over time.

This kit includes everything needed to upgrade your front braking system, including the calipers, rotors, brake lines, and mounting hardware. It's a comprehensive package for anyone looking to significantly improve their vehicle's braking performance for track days or spirited driving. Remember to consult the manufacturer's installation instructions for specific details regarding fitment and setup for your particular vehicle.
