This flywheel is designed to go hand in hand with our adapter plate kit that will allow you to bolt up Honda's K series motors to a Subaru EJ 6-Speed transmission (we also have a flywheel for the 5-speed transmission which is part # FW-K915-SF). This kit/flywheel utilizes the factory Honda starter.
The adapter plate is 1" thick which allows us to make this single disc flywheel to utilize any of our FX series clutch kits or any other OE style Subaru STi 6-Speed clutch kit.
We also offer a twin disc flywheel that will let you run one of our 850 Series twin discs for those wanting to make high horsepower.
