FactionFab Titanium Rear Brake Shim 2013-2026 BRZ / FRS / 86 | Thermal Barrier | Brake System Upgrade

Overview

The FactionFab Titanium Rear Brake Shim is a precision-engineered thermal barrier designed specifically for the rear brake calipers of the 2013-2026 Subaru BRZ, 2013-2017 Scion FR-S, and 2018-2024 Toyota 86/GR86. This simple yet effective upgrade addresses a critical issue faced by track and autocross enthusiasts: brake fade caused by excessive heat transfer into the caliper pistons. By inserting a titanium shim between the brake pad and caliper piston, it significantly reduces heat conduction, helping maintain consistent braking performance during aggressive driving sessions.

Crafted from CP3 Grade 2 titanium, these shims leverage titanium’s naturally low thermal conductivity and excellent bending characteristics to provide superior insulation compared to traditional steel shims. At 1.0mm thick, these shims offer better heat resistance than thinner competitors, ensuring your calipers and brake fluid stay cooler under demanding conditions. FactionFab’s focus on material quality and fitment precision makes these shims a reliable choice for Subaru BRZ and related platform owners seeking to enhance brake system durability and safety.

For Subaru BRZ and 86 owners pushing their cars on track days or autocross courses, these brake shims help prevent the dangerous effects of brake fluid boiling and fade, extending pad life and improving overall braking consistency. This upgrade is compatible with many popular brake pad models and fits vehicles equipped with FMSI D1124 pads, making it a practical and effective addition to your braking setup. It also qualifies for most SCCA and NASA racing classes, allowing you to maximize your track time with confidence.
