Brembo 19+ 330i Rear GTR BBK 4 Piston Billet 380x28 2pc Rotor Slotted Type3-Nickel

The 380x28mm two-piece rotor design in this Brembo GTR Big Brake Kit is a key feature, allowing for better heat management and reduced unsprung weight compared to a traditional single-piece rotor. This kit is specifically developed for the 2019 and newer BMW 330i, aiming to significantly upgrade your rear braking performance. The four-piston billet aluminum calipers are built for strength and rigidity, ensuring consistent clamping force even under demanding conditions.

This GTR kit utilizes slotted Type3 rotors with a nickel finish, which helps to dissipate heat and gasses effectively, keeping the pads in contact with a clean rotor surface for improved stopping power. The billet construction of the calipers means they are machined from a solid block of aluminum, resulting in a very strong and lightweight component that resists flex. This is crucial for maintaining pedal feel and braking precision when you push your vehicle hard.

When undertaking a big brake kit installation, it's important to ensure all components are properly fitted and bled according to the manufacturer's instructions. This kit is designed to be a comprehensive upgrade for the rear of your 330i, offering a substantial improvement in braking capability for track use or spirited driving. The nickel finish on the rotors not only adds a distinct look but also provides a layer of corrosion resistance.
