Wilwood ST FNSL4R Caliper 1.12/1.12 1.10 Rotor

If you're looking to fine-tune your vehicle's rear braking performance, especially when paired with larger front calipers, the Wilwood ST FNSL4R caliper is a solid choice. This caliper is engineered to provide a matched rear braking bias, ensuring your car stops predictably and powerfully. It's designed to work seamlessly with popular front setups like the Aero6/ST or other calipers featuring larger piston sizes, making it a versatile upgrade for performance-oriented builds.

What sets this caliper apart is its construction and internal features. It uses a forged billet body for strength and rigidity, which is crucial for consistent braking under demanding conditions. Inside, you'll find four Thermlock pistons. These pistons are designed to manage heat effectively, helping to prevent brake fade during spirited driving or track use. The caliper also comes standard with high-temperature seals, SRS bridge plates for added stiffness, and a two-piece bleed screw assembly for easier maintenance. Wilwood offers four high-temp race-only brake pad compounds in the 7416 pad type, allowing you to precisely tune your brake response and friction needs for your specific application.

This caliper is a radial mount design, offering widespread adaptability to various suspension setups. It's a popular choice for competition use and is often included in rear Big Brake kits. When installing, remember that proper brake fluid and bleeding procedures are essential for optimal performance. While this caliper is built for performance, it's important to select the correct brake pads from the available compounds to match your driving style and temperature requirements.
