Is there a real reason to use all wheel drive for this? Quick cornering is really not a concern in this application - your only turning left.

Also, you could put more of the batts to the left hand side of the car to improve the centripital forces during cornering, but you'd also have to comp your steering for getting down the straight. How much straight is there on that track? Enough to worry about?

Your going to want really slow steering response - a slight over steer at 90 will spell certain death!

You MAY want to be particulary careful with your aero control at that speed. I'd put adjustable screws at your body attach points to be able to screw your body up/down.

I think this is very interesting (I'm a huge NASCAR fan). I look forward to seeing your results.
