Race Technologies 2421 Brake Pad Compound Comparison

RE10 Racing Compound

Race Technologies RE10 is a competition-focused friction material engineered for consistent braking performance under sustained high temperatures. Designed for track days, sprint racing, endurance racing, and club competition, RE10 provides strong initial bite, excellent modulation, and dependable performance throughout extended sessions.

As a dedicated racing compound, RE10 may generate increased brake dust and noise during normal street driving and performs best within its intended operating temperature range.

TS20 Street and Track Compound

Race Technologies TS20 is designed for drivers who regularly enjoy spirited street driving, HPDE events, and occasional track days. TS20 offers excellent cold response, predictable modulation, and impressive fade resistance while maintaining more street-friendly characteristics than a dedicated racing compound.

Choosing Between RE10 and TS20

Select RE10 when your vehicle is primarily used for competition or aggressive track driving where maximum thermal capacity and repeatable braking performance are required. Choose TS20 when your vehicle serves double duty on the street and at the track, providing an excellent balance of performance, drivability, and durability.

Brake pad selection should consider vehicle weight, tire grip, rotor design, brake cooling, driving style, and operating temperatures. If you need assistance selecting the best compound, the Competition Motorsport team is ready to help.

Why Choose Race Technologies 2421 Brake Pads?

The compact 2421 pad shape is engineered to provide outstanding braking consistency, excellent pedal feel, and reliable thermal performance. Combined with Race Technologies' advanced friction materials, the 2421 delivers the confidence required for demanding performance driving while maintaining exceptional consistency lap after lap.

Always verify the 112 mm width, 74 mm height, D48 profile, and 15.5 mm thickness against your existing brake pads before ordering to ensure proper fitment.

Note: RE10 is a "racing use only" pad.

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.
