flat support surface for friction lining and clutch pressure plate (replica plates are often warped 1mm)
300% larger support surface for the friction lining (with the replica plate, the friction lining is only on a 3 to 4mm wide ring on)
increase from the transmittable torque by about 30%
no pulling out of the threaded bushings (higher strength, manufacturing from one piece)
better separation behaviour and better dosability of the clutch
better axial guidance of the clutch plate
made of tool steel and hardened, burnished for long life
fits plug-and-play
