Project Mu Club Racer RC09 Rear Brake Pads

For 1983–1987 Toyota Corolla AE86 Trueno / Levin and 1985–1987 U.S.-Market Corolla Sport AE86 GT-S with Factory Rear Disc Brakes & 1985–1987 Toyota

Overview

The Project Mu Club Racer RC09 Rear Brake Pads are circuit-focused racing pads for rear disc brake-equipped Toyota AE86 applications. The RC09 compound is designed for sustained high-temperature braking where consistent friction, heat resistance, and repeatable performance are priorities.

The super graphite metallic friction material operates across a 300–800°C rotor temperature range with a 0.42–0.55 μ friction coefficient. This makes the RC09 particularly well suited to track days, time attack, circuit racing, and other AE86 builds that regularly generate elevated brake temperatures.

Because the compound's intended operating range begins at 300°C, these pads are aimed at motorsport use rather than ordinary replacement street duty.

Key Features

  • Project Mu Club Racer RC09 circuit compound
  • 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
  • Rear brake application
  • 98.6 mm pad width
  • Intended for AE86 models equipped with rear disc brakes
  • Suited to track, time-attack, circuit, and competition use

Circuit-Focused RC09 Compound

The Club Racer RC09 compound is engineered around the elevated temperatures produced during repeated hard braking on a race circuit. Its high-temperature operating range allows the pad to maintain consistent braking characteristics during extended track sessions where conventional street-oriented friction materials can move outside their intended temperature window.

The rear RC09 pads can be paired with the corresponding front Club Racer compound to build a matched circuit-focused braking setup while retaining the factory-style AE86 disc brake configuration.

Vehicle Fitment

Toyota Sprinter Trueno

  • 1983–1987 Toyota Corolla AE86 – Trueno (JDM) – 4A-GE – Factory Rear Disc Brakes – Rear

Toyota Corolla Levin

  • 1983–1987 Toyota Corolla AE86 – Levin (JDM) – 4A-GE – Factory Rear Disc Brakes – Rear

Toyota Corolla Sport GT-S

  • 1985–1987 Toyota Corolla Sport AE86 – GT-S (U.S.-Market) – 4A-GE – Factory Rear Disc Brakes – Rear

Fitment Notes

  • Rear brake application only
  • Requires the factory-style AE86 rear disc brake configuration
  • U.S.-market application is 1985–1987 Toyota Corolla Sport GT-S
  • Does not fit factory rear drum brake applications such as the U.S.-market AE86 SR5
  • Circuit-focused racing compound
  • Proper rotor condition and brake-pad bedding procedures are important when installing performance brake pads

Project Mu AE86 Front Brake Pad Comparison

Brake Pad Primary Use Rotor Temperature Friction Coefficient Character
TYPE NS Daily / Street 0–400°C 0.37–0.40μ Street-focused with emphasis on lower noise and dust
B-Force Performance Street / Canyon / Autocross / Light Track 0–500°C 0.32–0.45μ Additional thermal capacity while retaining street usability
TYPE HC+ Aggressive Street / Track Day 0–800°C 0.43–0.58μ Higher-friction compound with a very broad operating range
HC M1 Performance Street / Track Day 50–800°C 0.41–0.55μ Linear modulation with strong high-temperature stability
Club Racer RC09 Dedicated Circuit / Competition 300–800°C 0.42–0.55μ 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.

Selection Guide

  • Daily Driver / Restoration / Street: TYPE NS
  • Performance Street / Canyon / Autocross / Light Track: B-Force
  • Aggressive Street / Track Day: TYPE HC+
  • Premium Performance Street / Frequent Track Use: HC M1
  • Dedicated Circuit / Competition: Club Racer RC09
