Project Mu Club Racer RC09 Front Brake Pads
For 1983–1987 Toyota Corolla AE86 Trueno / Levin and 1984–1987 U.S.-Market Corolla Sport AE86
Overview
The Project Mu Club Racer RC09 Front Brake Pads are circuit-focused racing pads for Toyota AE86 front brake applications. Developed for sustained high-temperature braking, RC09 prioritizes consistent friction, fade resistance, and repeated hard-braking performance during circuit driving and competition.
The super graphite metallic compound operates across an applicable rotor-temperature range of 300–800°C (572–1,472°F) with a 0.42–0.55 μ friction coefficient. This elevated operating range makes RC09 especially appropriate for dedicated track cars, time-attack builds, and other competition-focused AE86s.
Because the intended operating range begins at 300°C, RC09 is not optimized for normal cold street operation. A street-oriented Project Mu compound such as TYPE NS or B-Force is better suited to AE86s that spend most of their time on public roads.
Key Features

- Project Mu Club Racer RC09 formulation
- Super graphite metallic friction material
- 300–800°C applicable rotor-temperature range
- 0.42–0.55 μ friction coefficient
- Designed for sustained high-temperature braking and repeated hard use
- Suitable for circuit, time attack, and competition applications
- Complete front axle brake-pad set
- Fits the factory front brake-pad application used by the listed JDM and U.S.-market AE86 models
Circuit-Focused RC09 Compound
Club Racer RC09 is engineered around the elevated brake temperatures generated during circuit driving. Unlike street-oriented pads designed to work effectively from low rotor temperatures, RC09 has an intended operating threshold of 300°C.
Once within its operating range, the compound provides braking performance through rotor temperatures up to 800°C, making it well suited to repeated high-energy braking where thermal stability takes priority over street-oriented characteristics such as cold response, noise, and dust.
For daily driving, restoration builds, canyon use, autocross, or occasional light track use, a lower-temperature Project Mu compound will generally provide a more appropriate balance.

Project Mu AE86 Front Brake Pad Comparison
| Brake Pad | Primary Use | Rotor Temperature | Friction Coefficient | Character |
|---|---|---|---|---|
| TYPE NS | Daily / Street | 0–400°C | 0.37–0.40 μ | Street-focused with reduced noise and dust |
| B-Force | Performance Street / Canyon / Autocross / Light Track | 0–500°C | 0.32–0.45 μ | Added thermal capacity while retaining street usability |
| TYPE HC+ | Aggressive Street / Track Day | 0–800°C | 0.43–0.58 μ | Higher friction with broad temperature capability |
| HC M1 | Premium Performance Street / Track Day | 50–800°C | 0.41–0.55 μ | Linear control with strong high-temperature stability |
| Club Racer RC09 | Dedicated Circuit / Competition | 300–800°C | 0.42–0.55 μ | Race-focused compound for sustained high-temperature braking |
TYPE NS is the street-focused choice for regularly driven AE86s where cold response, reduced dust, and reduced noise are priorities.
B-Force is the next step for a harder-driven street car. Its 0–500°C range adds thermal capacity for canyon driving, autocross, and occasional light track use without requiring elevated brake temperature before working effectively.
TYPE HC+ substantially increases friction capability while retaining a 0°C lower operating threshold, making it a strong aggressive-street and track-day crossover.
HC M1 provides a more refined high-performance character with linear pedal control, high-temperature stability, and a 50–800°C working range.
Club Racer RC09 is the dedicated circuit option. Its 300°C minimum operating temperature makes it substantially less suitable for normal cold street use.
