Description
Rather than treating clutch selection as a universal fit, the EXEDY Hyper Single Clutch Kit – 1985–1989 Corolla / 1986–1989 MR2 (Toyota) is organized specifically for 1985–1989 Corolla / 1986–1989 MR2 (Toyota), with configurations chosen around enthusiast street, autocross, HPDE, and modified performance builds.
EXEDY Engineering Background
EXEDY's clutch expertise began in Japan in 1923 and expanded worldwide through the Daikin Clutch legacy. Unlike brands focused only on aftermarket friction products, EXEDY also operates as an OEM powertrain supplier, bringing production-level engineering and validation experience into its street-performance and racing clutch programs.
What This EXEDY Product Does
EXEDY's performance single- and multi-plate systems are intended to raise torque capacity and heat tolerance while matching the engagement characteristics to the car's intended use. Stage 1 uses an organic friction strategy for the most street-friendly behavior; Stage 2 moves to cerametallic friction for harder use; Hyper systems add dedicated flywheel and multi-plate architecture for substantially higher-output builds.
Choose the least aggressive configuration that comfortably covers the engine's torque and heat load. That approach normally gives the best balance of drivability, service life, transmission friendliness, and track durability.
Configuration
- EXEDY Part Number: TH01SD
- Configuration: Hyper Single Clutch Kit
- Construction / Character: Application-specific EXEDY configuration; sprung-center disc
- Torque Rating: Application-specific / verify EXEDY rating
- Best Suited For: Use where this exact EXEDY configuration and fitment are required
How to Choose
For 1985–1989 Corolla / 1986–1989 MR2 (Toyota), this configuration makes the most sense when its intended duty matches the vehicle's actual power and use. Avoid overspecifying clutch aggressiveness: the best setup is the one that maintains the needed torque reserve while preserving usable modulation and protecting the rest of the driveline.
Key Technical Specifications
- Clamp Load: Stage 1/2 covers are designed around roughly 40% higher clamping load than the genuine part
- Pedal Effort: Typical Stage 1/2 increase is approximately 20–35%, application dependent
- Flywheel Compatibility: Stage 1/2 generally use the OEM flywheel unless noted; Hyper systems include/require their dedicated flywheel
- Certification: EXEDY Stage 1, Stage 2 and Lightweight Flywheel products are SFI 1.1 certified
- Vehicle Application: 1985–1989 Corolla / 1986–1989 MR2 (Toyota)
