Girodisc Rear Titanium Shims for Mitsubishi Lancer Evo 6-9, Evo X, Subaru WRX STI 2004-2020 - TS-0961-4

Girodisc TS-0961-4 Rear Titanium Shims

The Girodisc TS-0961-4 Rear Titanium Shims are engineered to combat the critical issue of brake fluid boiling, a common challenge faced during intense driving sessions. When brake fluid heats up, it can boil, leading to a compressible air pocket that results in a soft brake pedal feel. This is particularly prevalent in production vehicles that lack the advanced cooling systems found in dedicated racing machines.

Material and Thermal Properties

Constructed from Titanium 6AL-4V, these shims exhibit exceptional thermal resistance, with a thermal conductivity rating of just 6.7 W/mk. In comparison:

  • Steel: 52 W/mk
  • Aluminum: 130 W/mk

This low thermal conductivity means that the TS-0961-4 shims effectively minimize heat transfer from the brake pads to the caliper pistons, thereby keeping the brake fluid cooler during high-performance scenarios.

Design and Installation

Each shim is water jet cut to precise dimensions, ensuring a perfect fit without the need for additional cutting or modifications. This design feature simplifies installation, allowing for a straightforward upgrade that enhances braking performance without the hassle.

Fitment

The Girodisc TS-0961-4 is compatible with the following models:

  • Mitsubishi Lancer Evo 6-9
  • Mitsubishi Lancer Evo X
  • Subaru Impreza WRX STi (Requires trimmed rear pads) 2004-2017
  • Subaru WRX with Brembo calipers Performance Pack, Series White 2020

Additional Notes

  • Price is per axle (includes four pieces).

For those planning to tackle multiple track days or pushing their vehicles to the limit, the Girodisc TS-0961-4 Rear Titanium Shims are a cost-effective solution to maintaining brake performance and reliability.
