Brembo 97-04 986 Boxster S Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-1-Black

The cast iron caliper body on this Brembo rear Big Brake Kit is designed to handle the heat generated by spirited driving, especially on a 986 Boxster S. This kit replaces your factory rear braking components with a substantial 345mm x 28mm two-piece rotor and a robust 4-piston caliper, offering a significant upgrade in stopping power and heat management. The two-piece rotor design, where the rotor ring is separate from the hat, helps reduce weight and allows for better thermal expansion, which can prevent warping under heavy use.

You'll notice improved pedal feel and more consistent braking performance, particularly during repeated stops or when driving the car hard. The Type-1 slotting pattern on the rotors is chosen for its effectiveness in clearing out brake dust and gases, ensuring the pad stays in contact with a clean rotor surface for optimal friction. This helps maintain braking effectiveness when you need it most. The black finish on the calipers adds a clean, performance-oriented look behind your wheels.

This kit is a comprehensive upgrade for the rear of your 986 Boxster S, intended for owners who demand more from their braking system. It's a substantial change from the stock setup, so be prepared for a noticeable difference in how your car slows down. Ensure you have adequate clearance for the larger caliper and rotor assembly within your wheels; consulting the manufacturer's wheel fitment guide is recommended.
