To me, stock is something approximating what would come from the factory. No street car comes with R-comps, so they shouldn't be allowed. SCCA has too many classes as it is. You'd think that they'd start with a genuinely "stock" class, and allow Rs on the plethora of modified classes rather than muddying things by allowing a modification as profound as Rs in "stock".
Again, we are forgetting what the conditions were when the rules were written. FSB's and shocks are allowed "stock" upgrades because "back in the day" most new cars were practically undrivable in auto-x. Having driven our '73 Volvo 1800ES with the OE FSB and then with an IPD FSB upgrade (which were available when the car was new), the difference in handling is dramatic. What was once literally scary is transformed.
Modern cars are much more capable off the showroom floor. This is obvious... but what would you do? Change the rules so that a guy who has been running the same car for 30 years in his local events and doesn't give a hoot about nationals (more common that you would think) is now bumped into a class where his car is hopelessly outclassed?
And while we refer to A6's and V710's as "r-comps" they are DOT approved, street legal tires. Treadwear ratings are a moving target at best... For example, the Dunlop Star Spec (TW 200) has beaten a number of other "softer" tires (TW 140) in comparison tests. So I have little doubt that Hoosier would mildly rework the A6 or R6 into a 140 rated tire.
It really isn't as simple as it sounds and the SEB has been down this road before. Are the current rules perfect? No. But for the most part they work and provide a stable platform for competition.
