At the very least, I think we have some glaring discrepancies regarding the relative burden of penalties for things such as tires vs. those for other improvements, such as weight reduction. As Kary has pointed out, no single influence on lap times is greater than tire choice, and the technology is changing rapidly. I have argued previously that 4 points for a sticky DOT-R tire is not nearly the equivalent of a 4-point penalty for a 150-lb. weight reduction, no matter what weight your Porsche is. I think we need to look at all penalties in this way, for an eye towards what the practical advantage in reducing lap times is for each one, and make them as consistent as possible. This is not a simple task, as Greg has pointed out.
I would vote for a change in our current points system where modification are level set against each other in relation to the actual speed potential improvement the modificiation could provide. As you stated these current points systems are really outdated and unfair. The issue is it would be difficult to come up with relative speed potential for improvements across the entire Porsche era's. The mere fact that the technologies change so much will render such an idea broken somewhere. I guess that is why I was proposing the elimination of those and llow people to improve the car to compete in a W/H ration class.
Regardless of the eventual, practical outcome of his or any other proposals, Kary should be commended for urging us to "think outside the bun," even if the end result is not a revolutionary overhaul of the rules. The discussion could lead us to some valuable evolutionary tweaks that no one has thought of before, simply because of inertia or ennui or a lack of imagination.
Thank you Tom, but you and others should also be commended as well as I feel like this is one of the best threads I have seen with great suggestions, multiple people contributing, and is staying on topic very well!
