Ferris, the thing that makes me wonder about 40 laps split in half. You say everybody will stop on the front stretch midway...so if a guy has worked to gain a 1/2 straightaway on a guy he loses it at the half way point. I don't know about you, but I would think the first half won't be the best racing we could see...rather drivers 'saving themselves' for the last 20.
Solution, instead of fuel tanks, strap whole fuel can on the back of the chassis and turn em loose for 40. THEN we will see who's tough LOL
