Ok now still while trying to decide which clutch to go with (was thinking of going with the ACT HDSS with Unorthadox flywheel) I heard that the ACT clutch with sometimes lock out in high RPM's, so now I don't know what the heck to do. I heard Clutch Masters makes a good product, then I saw something on XTD but don't know anything about them or heard anything about them. I know their setup is cheap in price but does anybody know if they are any good?
