Wilwood 15-23 Ford Mustang Forged Superlite 4R Rear Big Brake Kit 14.00in Rotor (Anodized)

Wilwood is well-known for making serious braking components for performance vehicles. This rear big brake kit is built for competition-focused 2015 and up Ford Mustangs, designed to work seamlessly with their FSL6R and AERO6 front kits. If you're building a Mustang for the track or serious performance driving, this kit offers a significant upgrade over stock braking hardware.

The FNSL4R calipers in this kit are forged for strength and feature a Type III hard anodized finish that's resistant to high temperatures and fluids. Inside, you'll find stainless steel pistons that help slow heat transfer from the brake pads to the caliper, along with high-temperature seals to ensure reliability even under sustained heavy use. The kit includes GT series directional vane competition rotors, which are engineered for efficient cooling. These rotors mount to the drive axles using forged aluminum hats, and the entire setup attaches using radial mount brackets that fit into the stock caliper locations. You'll also get high-temperature, high-friction race compound brake pads and all the necessary premium-grade fasteners to get everything installed.

This kit is a comprehensive solution for upgrading your Mustang's rear braking system for demanding conditions. It's important to note that this kit is intended for competition use and may require adjustments to your vehicle's brake bias to achieve optimal performance. Always refer to the manufacturer's installation instructions for proper setup and any specific requirements for your vehicle.
