Bridge Bolt Kit FSL4 1.25in Rotor

The Wilwood Bridge Bolt Kit FSL4 is a precision brake component designed for high-performance vehicle builds where brake caliper alignment and rotor fitment are critical. This kit is ideal for those upgrading classic cars, street rods, or performance brake systems, ensuring proper caliper centering and rotor seating to enhance braking efficiency.

The bridge bolts serve as the essential mechanical connection between the brake caliper mounting bracket and the rotor, maintaining concentricity and preventing lateral float. Constructed from hardened steel, these bolts are manufactured to tight tolerances, providing resistance to vibration loosening and thermal cycling, which is crucial during high-temperature braking scenarios.

This kit is indispensable for builders who prioritize braking safety and consistency, making it suitable for both street and track applications. Its lightweight design at 0.27 lbs ensures that it does not add unnecessary weight while delivering the rigidity needed for reliable pedal feel and rotor stability.
