GrimmSpeed Titanium Rear Brake Shim Set - 2-Piston Brembo - 2018-2021 STI

Product Overview

GrimmSpeed Titanium Rear Brake Shims install between the brake pads and caliper pistons to form a thermal barrier. Repeated hard braking transfers heat from the pads into the calipers and brake fluid; these precision-cut titanium shims help limit that transfer, reducing the risk of brake fade and supporting consistent braking performance during demanding driving.

Features

• High-strength 6AL-4V (Grade 5) titanium construction.
• Significantly lower thermal conductivity than traditional steel shims.
• Helps reduce heat transfer into brake calipers and brake fluid.
• Designed to help minimize brake fade during aggressive driving.
• Precision-cut for factory 2-piston Brembo rear brake calipers.
