Description
Improve rear brake thermal management with the FactionFab Titanium Rear Brake Shim Set, designed for vehicles equipped with FMSI D1124 rear 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 sessions can generate significant heat throughout the braking system. As temperatures increase, heat can transfer from the brake pad into the caliper piston and eventually the brake fluid. Excessive heat can contribute to brake fade and reduced braking consistency.
FactionFab Titanium Brake Shims help minimize this heat transfer by utilizing titanium's naturally low thermal conductivity compared with steel. Positioned between the brake pad and caliper piston, the 1.0mm-thick shim helps insulate the caliper from pad-generated heat while providing additional thermal protection during demanding driving.
Manufactured from CP3 / Grade 2 Titanium, these shims combine low thermal conductivity with excellent bending characteristics. Their 1.0mm thickness provides enhanced thermal insulation compared with thinner 0.5mm shim designs.

Improved Brake Thermal Management
Repeated braking generates substantial friction and heat between the brake pad and rotor. A portion of this heat can travel through the brake pad backing plate into the caliper piston. Excessive caliper temperatures can then transfer additional heat into the brake fluid, potentially contributing to fluid boiling and brake fade.
The FactionFab Titanium Rear Brake Shim acts as a thermal barrier between the brake pad and caliper piston, slowing the transfer of heat into the caliper. This additional insulation can help keep brake temperatures under control and maintain more consistent performance during repeated braking events.
These shims are particularly useful for drivers who participate in autocross, track days, spirited driving, or other high-demand applications where brake temperatures can rise significantly.

Fitment
FactionFab Titanium Rear Brake Shims fit vehicles using FMSI D1124 brake pads, including:
- 2013-2024 Subaru BRZ
- 2018-2024 Toyota 86 / GR86
- 2013-2017 Scion FR-S
- 2022-2024 Subaru WRX – 6MT, without Brembo brakes
- 2022+ Subaru WRX 6MT applications using FMSI D1124 pads
- 2022+ Subaru BRZ / Toyota GR86 applications using FMSI D1124 pads
Performance Brake Upgrade
The FactionFab Titanium Rear Brake Shim Set is a straightforward way to improve rear brake thermal management without replacing the factory caliper assembly. By reducing heat transfer from the brake pad into the caliper piston, these shims can help provide more consistent braking performance during repeated high-temperature stops.
For 2022+ Subaru WRX 6MT, Subaru BRZ, Toyota 86/GR86, and Scion FR-S applications, these titanium shims are an excellent addition to a performance brake setup for drivers who demand improved heat management during aggressive street driving, autocross, and track use.
Important: Verify your vehicle's exact brake configuration and FMSI D1124 pad compatibility before ordering. The 2022+ Subaru WRX application listed here is for 6MT models without the Brembo brake package. Competition regulations may vary by class and can change over time; check current SCCA and NASA rules before competition use.
