When it's time to replace your car's clutch, you face a crucial decision: upgrade or stick with stock? In many cases, upgrading is the preferred choice, especially when you pair the right clutch with a single mass flywheel. The secret to achieving the perfect blend of performance and driving experience lies in selecting a sprung hub clutch. This option allows you to enjoy the advantages of a single mass flywheel while eliminating issues like noise, vibration, and harshness (NVH), ensuring an outstanding driving performance.

| #SB533H-2 Variant | Use | Comments |
| "Sport" SPEC steel flywheel | daily driving; occassional drag strip | Use this with the SPEC steel single-mass flywheel. The clutch will be stiffer than the factory design but it will grab harder and stay connected with far less chance of slippage. The engagement point is changed but most drivers adjust within the first 100 miles. The failure-prone dual-mass flywheel is eliminated and a steel single-mass is used instead. Expect more noise and vibration from the steel but better reliability and slightly better performance. |
| "Super Sport" SPEC aluminum flywheel | more drag strip than street | Use this with the SPEC aluminum single-mass flywheel. The clutch will be stiffer than the factory design but it will grab harder and stay connected with far less chance of slippage. The engagement point is changed but most drivers adjust within the first 100 miles. The failure-prone dual-mass flywheel is eliminated and a lightweight aluminum single-mass is used instead. Expect a lot more noise and vibration with aluminum ("gearbox rattle") but better reliability and better performance. The engine will rev a lot faster too. |
