Wilwood ST FSL6R Caliper 1.62/1.12/1.12 1.25

Wilwood is well-known for making high-performance braking components, and their ST FSL6R calipers are a prime example of that expertise. These calipers are built for demanding situations where consistent stopping power and heat management are critical, like on dirt and asphalt ovals, off-road adventures, rally racing, and road courses. They offer a significant advantage over standard calipers by using a combination of advanced piston designs to keep your brakes working effectively, even under heavy use.

What sets these ST models apart is the inclusion of Thermlock® pistons. These special pistons are designed to block heat transfer from the brake pads, which can reduce the temperature inside the caliper, the brake fluid, and the seals by as much as 25% compared to typical stainless steel pistons. This improved heat management helps prevent brake fade and extends the life of your braking system components. Additionally, the calipers feature differential bore pistons. This means the pistons have different diameters, which helps to compensate for uneven loading and temperature differences across the brake pad. The result is reduced pad taper wear, meaning your pads wear more evenly and last longer, especially in sustained high-temperature braking scenarios.

You can get these calipers in a durable Quick-Silver Nickel finish or a tough Type III hard anodize. They are designed to be a direct fit for many performance applications, offering a solid option for anyone looking to upgrade their braking system for serious use. When you're pushing your vehicle hard, having reliable and heat-resistant calipers like these Wilwood ST FSL6R models can make a real difference in performance and safety.
