oil choice for 01 Cobra on track

About to do an oil change and as folks on here were so helpful with the alignment question I'm hoping to now get advice on oil choice. Traditionally I've put M1 5w30 in, but I'm thinking that's not the best choice for a car which sees the track. My M5 uses Edge 0w40, but I'm hesitant to put a 40 weight --even one on the lighter end of 40, like this one-- without being told it is a good idea with this engine. Also considering the Edge 0w30, though it's annoying it costs ~50% more.

Thoughts on what oil and weight to use for a backroads basher that does open track days?
