If you're doing any kind of real spirited driving....you should use a baffled large capacity pan. Don't use the stock pan for any kind of track event...just my $.02. If you do, oil starvation could be a real issue.
There's a number of good pan makers out there who do a nice job of baffled large capacity pans....Moroso, Aviaid, etc. They're reasonably priced and worth it.
Personally, I have a Moroso 7.5-quart rear sump pan with baffles. Pretty happy with the quality and fit/finish.
