Does that big rear spoiler do anything on a dirt track?

I don't have data, but I do think it helps. The car that consistently posts the best times has ridiculous spoilers (and a great driver too):

He tried various configurations and that works best. With speeds generally 35 to 60 mph, it appears that more extreme spoilers improve tire grip.
When Woody had this car he said that the biggest problem was getting the power to the ground. I may experiment with increasing the angle of attack more after I get a better feel for the car.

I would have guessed that those were air-brakes, not spoilers. Especially in the front.

Don't know about 986 engines, but M97s have weak rod bolts. Under protracted runs near redline, they stretch which allows the rod bearings to slip, resulting in a spun bearing or two. Prior to my bore scoring rebuild, I always shifted at 6K rpm rather than running up to 7200 redline. Wonder if that's what's going on with your engine?
