Description
Designed around the drivetrain package used in Flywheel Sport, the EXEDY Lightweight Flywheel – Flywheel Sport is intended for drivers prioritizing daily-driven and enthusiast street applications that need dependable engagement and OE-correct fitment and correct EXEDY component matching.
EXEDY Heritage
From its 1923 beginnings in Japan to its modern global OEM and racing programs, EXEDY has specialized in transferring torque reliably through the driveline. The company's Daikin Clutch heritage remains visible in a product philosophy built around precise engagement, thermal capacity, controlled clamp load, and application-specific engineering.
Driveline Role
EXEDY flywheels are engineered as matched driveline components rather than cosmetic weight reductions. Its lightweight performance flywheels use one-piece billet or forged chromoly steel construction to reduce rotational inertia while retaining high thermal capacity and integrated ring-gear strength.
A lighter flywheel can improve engine response and rev matching, but it can also reduce stored rotational energy and make low-speed takeoff more sensitive. It is best suited to drivers who value throttle response, faster transient behavior, and performance use over maximum factory-like smoothness.
Configuration
- EXEDY Part Number: ZF505A
- Configuration: Lightweight Flywheel
- Construction / Character: EXEDY application-specific flywheel
- Torque Rating: Not rated independently as a clutch torque-capacity figure
- Best Suited For: Clutch service or performance builds requiring the listed EXEDY flywheel fitment
Setup Guidance
For Flywheel Sport, 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.
Technical Notes
