Product Details
This Brembo PISTA Rear Race Big Brake Kit includes two 2-piece 380x28mm rotors with T3 slotting, designed specifically for the 2015-2023 Ford Mustang V6 and EcoBoost models (S550 chassis). Brembo's PISTA line is built for track-focused performance, offering significant upgrades over stock braking systems. The larger rotor diameter and increased thickness help dissipate heat more effectively, which is crucial for maintaining consistent stopping power during demanding track sessions or spirited driving.
The 2-piece rotor design features a floating hat that helps reduce stress on the rotor assembly and can make replacement easier down the line. Brembo's T3 slotting pattern is engineered to help keep the rotor surface clean and provide a consistent bite for your brake pads, while also helping to vent gases and dust away from the friction surface. This kit is a substantial upgrade for Mustang owners looking to improve their vehicle's braking performance for track days or competitive events. It's designed to work with the specific caliper mounting points on the S550 platform, ensuring a direct fit for the intended applications.
When installing a big brake kit like this, it's important to consider that it's a significant modification. You'll want to ensure your brake fluid is up to the task, and it's recommended to use high-performance brake fluid with a higher boiling point. While this kit focuses on the rear, it's part of a system, and you may want to consider matching front upgrades for a balanced braking feel. Always refer to the manufacturer's installation instructions for the most accurate guidance on proper fitment and setup.
