Brembo 12-15 335i/335i xDrive Exc MSport Brakes Rr GTS BBK 4Pis Cast 345x28 2pc Rtr Drill-Black HA

This Brembo rear brake kit is specifically for the 2012-2015 BMW 335i and 335i xDrive models, excluding those with the M Sport package. It's a significant upgrade designed to enhance your vehicle's stopping power and heat management. The kit includes everything you need to replace your factory rear brakes with a high-performance setup from a well-known name in braking technology.

At the heart of this kit are the Brembo 4-piston calipers, which offer increased clamping force over stock calipers. These are paired with 345x28mm two-piece rotors. The two-piece design helps reduce unsprung weight and allows for better thermal management, as the rotor hat is typically made of a lighter material like aluminum, which can expand and contract independently of the iron friction ring. The rotors are drilled, which helps to dissipate heat and gases, keeping the braking surface cleaner and improving performance under heavy use. The calipers feature a black finish for a clean look behind your wheels.

This is a comprehensive rear brake upgrade. When installing a big brake kit like this, it's always a good idea to inspect your brake lines and consider upgrading to stainless steel braided lines for a firmer pedal feel. You'll also want to ensure you have the correct brake fluid for high-performance applications. This kit is designed to be a direct replacement for the rear axle, providing a substantial improvement in braking performance and durability for your 335i.
