Product Details

If you're building a dedicated track car or a serious performance street machine, you know how critical brake system reliability is. The Wilwood FSLI4 caliper is built for those demanding situations, offering a well-built upgrade over stock components. This caliper is part of Wilwood's popular Superlite family, known for its performance in everything from short track racing to spirited road driving.

What sets this FSLI model apart is its updated internal fluid port design. Instead of external crossover tubes that could be damaged, the fluid passages are now routed internally. This not only cleans up the look but also eliminates a potential failure point. The symmetrical piston bore design means you can mount these calipers on either the left or right side, offering flexibility during installation. It uses 1.62-inch pistons and is designed for rotors up to 0.81 inches thick.

This caliper is a solid option for anyone looking to enhance their braking performance and durability. Ensure you have the correct mounting brackets and brake lines for your specific application, as these are sold separately.
