Can't you spend MORE on non-remotes now that perform BETTER?
Yes. And you can also spend more on RR shocks that perform even better. Containing costs by defining configuration rarely works in a race series. Its like banning assault rifles based on configuration (flash suppressor, pistol grip, etc.)

IMHO, SCCA is behind the curve regarding shocks. Shocks have become such an important part of suspension design and development that they need to be treated similar to tires as far as the rules are concerned. It might need to go as far as SCCA approving specific models from a number of manufacturers for each race series/category.
