It is insanely light in total weight. 7 lbs lighter in total weight as compared to the 10 lb Toda flywheel and Cusco clutch. Pretty amazing when you consider it uses a 1600 kg pressure plate as opposed to the 1050 kg on the Cusco and the 800 kg stock unit. It converts the clutch to push type and is good to 500 PS. The carbon disc is smoother engagement and lasts 3 times longer than cerometallic. It is also easier on the trans since it allows some slippage without needing springs (which can pop out at the most inconvinient time). We just finished test fitting one and made some changes to the old directions (which were wrong). So far the customer is estatic. The twin disc which should handle 800 ps is coming soon.
