I think you'd be better off sitting with $400 in your checking acct waiting for a closeout special on a clutch that way you've got one for when yours goes out. Double clutching is a waste of time now that we all for the most part run gearboxes with synchros.

You may even want to install a lightweight flywheel or crank pulley, since they'll reduce clutch wear even more by reducing the amount of mass the clutch has to slow down or speed up.

It's all about how you drive, get the timing down on when to let off the gas, unload the tranny, and then load it back up when you let the clutch out. Then again I'd rather burn the clutch up and save my gears/synchros than practice clutchless shifting and have to replace my transmission earlier.

To the OP, do you downshift when you're coasting to a stop?
