FactionFab Titanium Front Brake Shim F40 Brembo Pad | 1.0mm Thickness | Thermal Brake Shim

Overview

The FactionFab Titanium Front Brake Shim is a precision-engineered thermal barrier designed specifically for Subaru enthusiasts using F40 Brembo-style brake pads. This shim installs between the brake pad and caliper piston to significantly reduce heat transfer during aggressive driving conditions such as track days and autocross events. By insulating the caliper piston from excessive heat, it helps prevent brake fluid boiling and brake fade, ensuring consistent stopping power and enhanced safety under demanding use.

Crafted from 6AL-4V Grade 5 titanium, these shims leverage titanium’s naturally low thermal conductivity to outperform traditional steel shims. At 1.0mm thick, they provide superior insulation compared to thinner aftermarket alternatives, offering a more effective thermal barrier without compromising pad fitment or brake feel. FactionFab’s focus on motorsport-grade materials and fitment precision makes this product a trusted upgrade for Subaru drivers seeking reliable brake performance on the track.

For Subaru owners pushing their braking systems to the limit, these titanium shims extend brake pad life by reducing heat soak and fade, allowing for longer, more consistent hot laps. Compatible with a variety of motorsport and aftermarket brake kits using the FMSI D968 pad shape, this simple yet effective modification enhances both safety and performance, making it an essential addition for serious Subaru track enthusiasts.
