FactionFab Titanium Front Brake Shim F40 Brembo Pad

The FactionFab Titanium Front Brake Shims for F40 Brembo-style brake pads are designed to reduce heat transfer from the brake pads to the caliper pistons during demanding driving conditions. Frequent, aggressive braking during track days and autocross events generates substantial heat, which can transfer into the calipers and raise brake fluid temperatures. Excessive heat can contribute to fluid boiling and brake fade, making thermal management an important part of a performance braking system.

These shims create a thermal barrier between the back of the brake pad and the caliper piston, helping slow heat transfer into the caliper and brake fluid. Manufactured from 6AL-4V Grade 5 titanium, they use a 1.0mm-thick construction that provides a thermal barrier between the pad backing plate and piston.

Designed for drivers who push their braking systems during track sessions, these shims can help manage caliper temperatures, reduce the risk of heat-related brake fade, and support longer-lasting brake pad performance. They are an easy addition to compatible braking setups for drivers looking to increase consistency during repeated hard braking.

Each kit includes four titanium shims and is designed for brake pads using the FMSI D968 shape, commonly associated with F40-style Brembo brake applications. Compatibility extends to many motorsport and aftermarket brake kits that use this pad shape, so verify the pad backing plate dimensions before ordering.

FactionFab notes that these shims may qualify for use in many SCCA and NASA competition classes, but eligibility depends on the rules for the specific vehicle and class. Check the applicable regulations before competition use.
