The Performance Clutches F-6149-L1 lightweight flywheel, weighing 6.8 kg, is designed for drivers who want sharper throttle response, faster-revving performance and reliable operation even under higher loads. It is suitable for standard or modified SR20DET engine configurations.
Flywheel benefits
- Precision manufacturing for improved performance – With less rotating mass and inertia, the engine revs more quickly, shifting is more direct and the entire drivetrain responds faster.
- Robust construction for road and track – Made from high-quality forged 4140 steel and designed to withstand higher loads and forces without failure during everyday use.
- Direct installation – Designed to integrate with the original clutch system and gearbox interface, so no major modifications are required during installation.
- Improved driving feel – Replacing the standard flywheel with the F-6149-L1 provides a more pronounced feel when pulling away, better response through corners and a more direct drivetrain response.
It is suitable for you if:
- you drive a high-performance or modified vehicle and want to match the drivetrain to its performance;
- you want to improve the feel during everyday driving and hard acceleration;
- you are looking for a direct-fit upgrade compatible with the existing clutch system;
- you want better control, faster response and a more direct feel than with the standard flywheel.
The F-6149-L1 lightweight flywheel reduces rotating mass, providing faster engine response and more direct drivetrain operation.
Suitable for: Nissan 200SX I (S13) / II (S14), Nissan Silvia I (S14).
