If you get a mod clutch, that's all you need, but if you want to upgrade and get a lighter flywheel, you need to go non-mod conversion route. Simplest thing to do is order the CM replacement clutch for our car which will be modular (then, no need to order flywheel). The phantom grip (or whatever you choose to get) is independent and doesn't depend on what type of clutch you have. Hope that clears up any confusion I may have caused.
