A clutch kit includes all of the components of the clutch assembly - disc, pressure plate, and throw-bearing (release bearing).

This clutch uses components that are partially made from recycled materials. This is known as a remanufactured or rebuilt kit, and is a common practice with organic clutch materials. Even a clutch purchased from BMW directly may also be remanufactured. Note that this does not mean it's a greasy, worn-out used part! It only means that the organic material in the clutch disc, and possibly other components, have come from a recycled source. Using recycled materials lowers the overall product cost and is better for the environment. LuK stands behind the part with a two year warranty.

Additional items should also be replaced as part of the "while you're in there" work. This includes, but is not limited to, exhaust gaskets, transmission seals and bushings, driveshaft mounts, pilot bearing, and the rear main seal. In addition, the condition of the flywheel will be unknown until exposed with the clutch removed. Some flywheels may be resurfaced, however, it's not guaranteed. In the case of dual-mass flywheels, the typical replacement interval is every other clutch change (but sometimes sooner). Ordering the basic clutch kit is usually first on a long list of parts to replace at the same time.
