I am so much looking forward to checking out the action next week at Road America.
Idea, as this competition grows, how about two classes?
One class would be an unlimited class.
The other class would be limited to minimal modifications for cars still retaining the stock-style sustension. This 'slower' class may draw in more guys with modified stock suspension (tubular control arms, big sway bars, while still retaining leaf springs, etc.). This is what most pro-touring guys do.
This way the stock-style cars could still compete with each other for the fastest-in-class without trying to go up against the stuff with full custom race suspension under it.
This would give the companies that sell tubular replacement parts and sway bars a venue to show off their 'bolt-on' parts and compete at that level.
