I don't think its a matter of chassis sponsorship. It's a matter of how fast you are and just plain and simple doing whats fair and right. Plenty of Pro class drivers had NO sponsorship at all. The top 3 or so sportsman Amain qualifiers would have been in the Pro B and ran laps similair to the Pro drivers. Thats the problem. I would say thats why they should have run Pro. Having sponsorship makes it worse.
My pitman has no sponsorship, has been racing for one year and enter Pro Truggy. He finished in top 5 in the B main. He feels really good about his finish and that I have major respect for him. He wanted to push him self. Not sandbag and walk away with pretty easy win.
