Recently i've been hearing that dual clutchs have been wearing out the main bearings on the crankshaft shortly after installaition of the dual clutchs, is this ture or a real concern? I ask because i was planning on upgrading to a Ralliart dual clutch or the Exedy, but now i need to reseach this more before i pick a clutch. Do AP racing and Alcon make suitable units that can see some rare street use? I know the FQ400 has an Alcon unit. My car will be producing about 360hp at the crank when i get the clutch.
