Yeah, as Simon said, don't pan kick drum at all, that would probably lead to problems.

I differ with Simon in that I am open to panning the snare, though usually slightly .. mainly to add some dimension to other drums. In many recording setups, the live snare is pretty prominent, and is usually picked up by other mics also. Like overheads, hihat, and even the ride on the other side of the kit. So the panning/EQ on all those tracks can affect the end result snare sound.
In my opinion, drums are the most complicated tracks to mix, so you have to keep an open mind and try lots of stuff.

I've had moments where I EQ'd the crash cymbal mic and the snare suddenly had more (or less) presence in the mix.
So I always start with bass drum center, but am OK with moving the snare a bit..

Mixing drums ain't easy

I do not work here, but the benefits are still awesome
