Girodisc Rear Titanium Pad Shields for Subaru WRX | STI 2018-2021 w/ 2-Piece Rotors - TS-6027-4

Girodisc TS-6027-4 Rear Titanium Pad Shields

The Girodisc TS-6027-4 Rear Titanium Pad Shields are engineered to combat brake fluid boiling, a common issue for performance vehicles during intense driving conditions. This phenomenon occurs when heat from the rotors and pads transfers directly into the brake fluid through the caliper pistons. When the brake fluid reaches its boiling point, it releases air, leading to a spongy brake pedal and reduced stopping power. Production vehicles often struggle with this on track days due to their limited cooling systems compared to dedicated racing setups.

High-performance racing calipers utilize titanium caliper pistons for a reason: titanium boasts low thermal conductivity. This property minimizes heat transfer, helping to maintain cooler brake fluid temperatures. The TS-6027-4 takes this principle further by incorporating a thin titanium shim placed between the pad backing and the pistons. This design effectively reduces heat transfer to the brake fluid, ensuring consistent braking performance even under extreme conditions.

Material Comparison

To illustrate the effectiveness of titanium, consider the thermal conductivity ratings of common materials:

  • Titanium 6AL-4V: 6.7 W/mk
  • Steel: 52 W/mk
  • Aluminum: 130 W/mk

Titanium's significantly lower conductivity means it will transfer far less heat compared to steel and aluminum, making it an ideal choice for performance applications. For vehicles that will endure multiple track days, these titanium pad shields provide an economical solution to prevent brake fade and maintain pedal feel.

Product Features

  • Precision water jet cut for exact fitment—no cutting or grinding required.
  • Sold per axle (includes four pieces).
