Brembo 15-18 M3 Excl CC Brake Rr GT BBK 4Pis Cast 345x28 2pc Rotor Slotted TY3L - Silver

The 345x28mm two-piece rotors in this Brembo rear big brake kit are a key component, featuring a slotted design that helps clear heat and dust away from the pad surface. This is crucial for maintaining consistent braking performance, especially during spirited driving or track use where temperatures can climb rapidly. The kit is built around a four-piston caliper, which applies more even pressure across the brake pad surface compared to a standard two-piston caliper, leading to improved stopping power and better pad wear.

This Brembo GT Big Brake Kit is designed to be a significant upgrade over the factory braking system for the 2015-2018 BMW M3 models, excluding those with Carbon Ceramic brakes. The calipers are cast aluminum, offering a good balance of strength and light weight, which helps reduce unsprung mass. The two-piece rotor construction allows for better thermal management, as the aluminum hat can dissipate heat more effectively than a traditional one-piece rotor. The silver finish on the calipers provides a clean, performance-oriented look behind your wheels.

When installing this kit, you'll want to ensure you have the necessary tools and knowledge for a brake system overhaul. It's a substantial upgrade that will change the feel and performance of your vehicle's braking. We recommend consulting the manufacturer's installation guide for specific details and torque specifications. This kit is a popular choice for M3 owners looking to enhance their car's track capability and overall driving dynamics.
