Here we go again!
Here's an idea for y'all to consider instead of trying to add a bunch of new classes to fit these new super performance cars and restricting what we can race. Why not have a sub-class for each class we already have. The sub-classes would be OPEN classes, meaning open to any modifications excluding traction magnets. The open classes would be scheduled and raced separately from the non-open class, but racers could run their non-open class cars in the open class if they chose to. Here's how it would look, Classic Sports Car DivII Open, or Can Am Open, raced independently on any given race night. These classes would catch ANYTHING that came out, including exotic scratchbuilds. I would also separate out all current jointly raced divisions and race them as stand alone classes. In the case of our current mess we refer to as F1, I would change it to one or two specific categories of F1 cars with specific rules and throw all rest rest into the F1 Open Class. In this wat any one class could be raced and scored accurately, even for a point series race.
