Description
Improve brake thermal management with the FactionFab Titanium Front Brake Shim Set, designed for vehicles equipped with FMSI D1539 front brake pads. These precision-made titanium shims create a thermal barrier between the brake pad and caliper piston, helping reduce heat transfer into the caliper and brake fluid during repeated hard braking.
Aggressive street driving, autocross, and track use can generate significant heat in the braking system. As brake temperatures rise, heat can transfer from the pad into the caliper piston and eventually the brake fluid. Excessive brake fluid temperatures can contribute to brake fade and reduced braking performance.
FactionFab Titanium Brake Shims help address this issue by using titanium's naturally low thermal conductivity. Installed between the brake pad and caliper piston, the 1.0mm-thick titanium shim slows heat transfer while providing additional thermal protection for the braking system.
Made from CP3 / Grade 2 Titanium, these shims offer excellent thermal insulation along with favorable bending characteristics for installation. The 1.0mm thickness also provides greater insulation than thinner 0.5mm shim designs.

Brake Heat Management
Repeated hard braking produces substantial friction and heat between the brake pad and rotor. Some of this heat travels through the back of the brake pad into the caliper piston. As caliper temperatures increase, additional heat can transfer into the brake fluid, potentially contributing to fluid boiling and brake fade.
The FactionFab Titanium Brake Shim acts as a thermal barrier between the brake pad and caliper piston, slowing this heat transfer and helping protect the caliper and brake fluid from excessive temperatures.
The result is improved thermal management and more consistent braking performance during repeated braking events. This makes the shims particularly useful for vehicles used in autocross, track days, spirited driving, and other demanding applications.

Ideal for Track and Performance Use
The FactionFab Titanium Front Brake Shim Set is a simple brake-system upgrade designed to improve thermal management without requiring replacement of the factory calipers. By reducing heat transfer from the brake pad into the caliper piston, these shims can help maintain consistent braking performance during repeated high-temperature stops.
For 2011-2014 Subaru WRX, Subaru BRZ, Toyota 86/GR86, and Scion FR-S owners, these titanium brake shims provide an effective solution for additional brake heat protection during aggressive street driving, autocross, and track sessions.
Note: Verify your vehicle's exact brake configuration and FMSI D1539 pad compatibility before ordering. Competition regulations can vary by class and may change over time, so check current SCCA and NASA rules before competition use.
