Testimonials

A car part I ordered for my son for Christmas 2015 was damaged during shipping and arrived cracked. I called Lancer Shop and spoke with Jay. He as very prompt and efficient, and told me exactly what to do to get the return authorization process moving. He kept in contact with me over the next few days, and within a few days from the first call I made to Lancer, a new part was shipped. I highly recommend doing business with Lancer, and please know if you ever have problem they will fix it promptly and efficiently! Thank you Lancer!

Girodisc Rear Titanium Shields & Shims- Evo 8/9/X

Product Description

The problem of brake fluid boiling is simply traced to heat transferring from the rotors and pads directly into the fluid through the caliper pistons. When brake fluid boils, it releases air that is normally part of the molecular structure of the fluid. This air is compressible of course, and the brake pedal goes to the floor instead of moving the caliper pistons. Production cars tend to suffer from this on track days more as they don't usually have the extensive cooling duct and exotic brake materials as true racing cars.True racing only brake calipers generally come with titanium caliper pistons for one reason. Titanium as a material, has low thermal conductivity. This means that it is very bad at transferring heat. Which is good if you are trying to keep your fluid cool.

The Girodisc solution to help prevent fluid boiling is to use a thin titanium shim placed between the pad back and the pistons, to keep the braking heat from transferring into the pistons and fluid.Here is a comparison of materials and their relative thermal conductivity ratings
Titanium 6AL-4V 6.7 W/mkSteel 52 W/mkAluminum 130 W/mk

You can see that Titanium will transfer far less heat than steel and especially aluminum. For cars that are going to see hard or multiple track days, these shims are cheap protection from loosing the pedal due to boiling at the wrong time and making the day very expensive.

Water jet cut to exact size, no cutting, grinding, or swearing involved.
