Brembo 08-13 M3 Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Black HA

This is the Brembo Rear GTS Big Brake Kit for the 2008-2013 BMW M3. It's a comprehensive upgrade designed to significantly improve your M3's braking performance, especially under demanding conditions. The kit includes everything you need to replace your stock rear braking system with a high-performance setup from a well-known name in braking technology.

At the heart of this kit are the 4-piston calipers, which offer more clamping force than your factory calipers. These work with the 345x28mm two-piece rotors. The rotors are slotted, which helps to dissipate heat and gas buildup during hard braking, keeping the pads in better contact with the rotor surface for more consistent stopping power. The two-piece design allows for better thermal management and can reduce unsprung weight compared to a single-piece rotor. The calipers come in a sleek Black HA finish, adding a touch of aggressive style to your M3's rear end.

This kit is a substantial upgrade for any M3 owner looking to get the most out of their vehicle's braking system. It’s a direct replacement for the factory components, meaning it's designed to fit without major modifications. You'll notice improved pedal feel and fade resistance, which is crucial for track use or spirited driving. Ensure you have the necessary tools and knowledge for brake system work, or consider professional installation to get the most out of this performance brake kit.
