Don't worry.... the resident "I've used stock drums forever and everyone's doing it wrong...." will check In and make you feel all better again.

We learned all about this ordeal back in the pre internet days. 10 sec car, launched, broke rear gear, shocked sprag, and away she went. All 727's we've run since have had billet drums and blanket since witnessing this. For the price of the drum vs the possible damage it's a no brainer.
