Brembo 12-15 335i/335i xDrive MSport Brakes Rr GTR BBK 4Pis Billet 345x28 2pc Rtr Slot Type1-Nickel

This Brembo GTR Big Brake Kit for the rear of your 2012-2015 BMW 335i and 335i xDrive M Sport models includes everything you need for a significant upgrade to your braking system. You get a pair of 4-piston billet aluminum calipers, a pair of 345x28mm two-piece slotted rotors with a nickel finish, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brakes, offering improved stopping power and thermal management for spirited driving and track use.

The calipers are forged from billet aluminum, which is both strong and lightweight, helping to reduce unsprung weight. They feature a 4-piston design, providing more clamping force than stock calipers, which translates to quicker stops. The two-piece rotors are constructed with a cast iron friction ring and an aluminum hat, reducing weight and allowing for thermal expansion without warping. The Type 1 slotting pattern on the rotors helps to sweep away dust and gas, maintaining consistent pad contact and performance, especially under heavy braking conditions. The nickel finish on the rotors adds a layer of corrosion resistance and a distinct look.

When installing this kit, you'll want to ensure you have the correct tools and refer to Brembo's installation guide for specific procedures. Because this is a significant brake upgrade, it's often paired with a corresponding front big brake kit to balance the braking system. This kit is a substantial investment for drivers who demand more from their vehicle's braking performance, offering a well-built solution for enhanced control and durability.
