There is a reason high performance vehicles do not run drums. Disc brakes dissipate heat WAY BETTER than drums. And as Party Truck said there are less parts, which means less to go wrong. Sure, drums have more surface area to stop a tire, which I'm sure is why big rigs still use them.

You will have to face it one day BJ...discs are superior to drums.

Gun it and run it!
