Description
Improve rear brake thermal management with the FactionFab Titanium Rear Brake Shim Set, specifically designed for 2-piston Brembo rear brake applications using FMSI D961 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 aggressive and repeated braking.
During track days, autocross events, and spirited driving, repeated hard braking can generate substantial heat throughout the braking system. Excessive heat transferred through the brake pad into the caliper can increase brake fluid temperatures and contribute to brake fade. FactionFab Titanium Brake Shims help minimize this heat transfer by taking advantage of titanium's naturally low thermal conductivity compared with steel.
Each shim is manufactured from 6AL-4V / Grade 5 Titanium and measures 1.0mm thick, providing effective thermal insulation between the brake pad and caliper piston. The 1.0mm thickness offers additional insulation compared with thinner 0.5mm shim designs, making these shims particularly useful for high-temperature performance applications.
By helping reduce heat transfer into the caliper, FactionFab Titanium Rear Brake Shims can help maintain more consistent braking performance, reduce the likelihood of heat-related brake fade, and potentially extend brake pad life during demanding use.

How Titanium Brake Shims Work
Under heavy braking, friction between the brake pad and rotor produces significant heat. Some of this heat can travel through the back of the brake pad and into the caliper piston. As caliper temperatures increase, heat can eventually 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. Titanium's low thermal conductivity helps slow the transfer of heat into the caliper, providing additional protection for the braking system during repeated high-temperature braking.
This makes the shims especially beneficial for drivers who regularly participate in autocross, track days, or aggressive performance driving.

Fitment
FactionFab Titanium Rear Brake Shims are designed to fit many applications using FMSI D961 brake pads, including:
- 2004-2017 Subaru STI
- 2003-2006 Mitsubishi Lancer Evolution
- 2003-2009 Nissan 350Z with Brembo brakes
Ideal for Track and Performance Driving
The FactionFab Titanium Rear Brake Shim Set is a straightforward brake upgrade for drivers looking to improve thermal management without replacing their factory Brembo calipers. By reducing heat transfer from the brake pad into the caliper piston, these shims can help provide more consistent braking performance during repeated hard stops.
For 2004-2017 Subaru STI owners, as well as compatible Mitsubishi Lancer Evolution and Nissan 350Z Brembo applications, these titanium shims are an excellent addition to a performance-oriented brake setup.
Note: Verify your vehicle's brake configuration and brake pad shape/FMSI number before ordering. SCCA and NASA competition rules may vary by class and can change over time; always verify current regulations before competition use.
