Brembo 08-13 135i Rear GTR BBK 4 Piston Billet 345x28 2pc Rotor Slotted TY3L - Nickel

Brembo is a name many people trust when it comes to serious braking performance, and they're known for their high-performance brake systems. This GTR Big Brake Kit is a prime example, designed for the rear of your 2008-2013 BMW 135i. If you're looking to significantly upgrade your car's stopping ability, especially for track use or spirited driving, this kit is built for that purpose. It replaces your factory rear brakes with a much more robust setup that can handle more heat and deliver more consistent braking force.

At the heart of this kit are the 4-piston GTR calipers, which offer more clamping force than stock. These calipers are paired with 2-piece, 345x28mm rotors that are slotted. The slots on the rotor surface help to sweep away dust and gas that can build up during hard braking, which helps maintain consistent friction between the pad and rotor. The rotors themselves are made from a high-carbon cast iron for durability and heat dissipation, and the 2-piece design allows for better thermal management and can reduce weight compared to a single-piece rotor. The nickel finish on the calipers adds a layer of corrosion resistance and a distinct look.

This is a comprehensive kit designed to be a substantial upgrade over your stock braking system. It includes the calipers, rotors, and likely all the necessary hardware to get them installed, though it's always a good idea to consult the manufacturer's instructions for any specific installation requirements or additional components you might need. If you're pushing your 135i hard, this Brembo GTR kit is engineered to help you slow down with more confidence and control.
