Brembo 08-13 M3 Rear GTR BBK 4 Piston Billet 345x28 2pc Rotor Slotted TY3L - Nickel

This Brembo GTR Big Brake Kit for the 2008-2013 BMW M3 includes everything you need to upgrade your rear braking system. You get a pair of Brembo 4-piston billet aluminum calipers with a nickel finish, two 345x28mm two-piece slotted rotors, and all the necessary hardware for installation. This kit is designed to give your M3 a significant boost in stopping power and heat management, crucial for spirited driving and track use.

The calipers are crafted from billet aluminum, which is both strong and lightweight, helping to reduce unsprung weight. The 4-piston design offers increased clamping force over stock calipers, translating to more consistent braking performance. The two-piece rotors feature a 345mm diameter and a 28mm thickness, with slots machined into the braking surface. These slots help to vent gases and heat away from the pad surface, which keeps the brakes cooler and reduces the chance of fade during hard use. The nickel finish on the calipers not only looks sharp but also offers good corrosion resistance.

Installing a big brake kit like this is a substantial upgrade for your M3. It's designed to work with your existing brake master cylinder and lines, but it's always a good idea to consult the manufacturer's installation guide for specific details and torque specifications. The improved thermal capacity and clamping force will make a noticeable difference when you need to slow down quickly and repeatedly.
