Running a "racing use only" pad on the street could produce excessive noise and dust.Disc wear could be accelerated if driven at cold temperatures or used in the incorrect temperature range.
Racing pads are designed to work in specific temperature ranges, so it's important to choose the right compound for the environment the vehicle will be used in.
Pad compounds are run on a brake dynamometer over multiple brake applications ("stops") to test the materials in a controlled environment and obtain accurate data. Wear rates and operating temperatures can be influenced by car set-up, grip levels, track layout, and other variables.

Girodisc Titanium Brake Pad Shields
Fitment: Porsche 991, 992, GT4 (Front)
The problem of brake fluid boiling is caused by braking 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, so brake pedal pressure compresses this air instead of pushing brake fluid and moving the caliper pistons. The brake pedal goes to the floor.
Production street cars tend to suffer from this on track days because they don't have the extensive cooling ducts and exotic brake materials found on race cars. Race-only brake calipers generally come with titanium caliper pistons for one reason: titanium has very low thermal conductivity, which means it's bad at transferring heat.
That's good if you're trying to keep your brake fluid from boiling. Here's a comparison of materials and their relative thermal conductivity ratings in Watts per meter-Kelvin (lower is better):
Titanium 6AL-4V = 6.7 W/mK
Steel = 52 W/mK
Aluminum = 130 W/mK
Most fixed calipers use aluminum pistons which are, unfortunately, excellent at transferring braking heat to your brake fluid. Our solution is to place Girodisc's thin titanium shims between each brake pad and the caliper pistons. This helps prevent braking heat from transferring into the pistons and, thus, into the fluid.
For cars that are going to see hard driving or multiple track days, these shims are affordable protection against losing your brake pedal at the worst possible time, making your track day very expensive.
Water-jet cut to exact size, so there's no cutting, grinding, or swearing involved.
Price is per axle (four shims)

Castrol React SRF Synthetic Racing Brake Fluid (1000 ml)
from $99.95
Castrol React SRF Racing Brake Fluid
Ultra-High Wet Boiling Point Makes Castrol SRF A Standout
Castrol React SRF Racing Brake Fluid is an ultra-high performance brake fluid popular with many of the highest performing auto racing teams around the world. The key to Castrol SRF brake fluid's performance is its silicon-ester technology. Not only is it less hygroscopic (i.e., it absorbs less water) than typical glycol-based brake fluids, Castrol SRF also reacts chemically with any absorbed water to further reduce its adverse effects on high-temperature braking performance.
The result is an almost unheard of 518° F (270° C) wet boiling point, more than 100° F higher than most other racing brake fluids!
Exceeds SAE 1703, ISO 4925, JIS K2233, FMVSS No. 116 DOT3 and DOT 4 specifications.
Note: Castrol SRF is not a silicone-based brake fluid (i.e., DOT 5) and is compatible with most factory brake systems and fluids, including DOT 3 and DOT 4 fluids. Always follow vehicle manufacturer's recommendations when adding brake fluid.
Castrol React SRF Racing Brake Fluid Typical Properties:
Dry Boiling Point: 590°F (310°C)
Wet Boiling Point: 518°F (270°C)
Superior anti-vapor lock properties
