When replacing your clutch, we highly recommend a lightweight flywheel such as the SPEC Aluminum Flywheel, which is lightweight, and reduces rotational mass of your engine, allowing your engine to rev easier and faster. Each SPEC Flywheel is manufactured to be within .001 of machine tolerance and allows your clutch to have a smooth surface to mate to. Does not need to be machined, and is ready to install. We highly recommend using a SPEC Aluminum Flywheel along with a SPEC Clutch Kit for the best combination of clutch pedal feel, quick revving lightweight assemblies, and high performance.
