Here is a valid question to everyone, Who and when was it decided that R-compound tires should be legal for stock classes?
It goes back aways. When I first started back in 2009, we had a long, drawn out discussion about this subject. Some quotes from that discussion by a guy who was there:
Had the economy not crashed you'd have been 'lucky' enough to watch a first-hand re-enactment that rule's origin over in the ST* classes (it's still brewing, actually). In the 1980s there was a Manufacturer's tire war in the Stock classes (yeah - in Autocross!?!) where a handful of competitors had access to custom tires that were completely DOT legal... for about 25 feet of travel. Then they were basically full race rubber.
After numerous attempts to reign them in, the Solo people simply gave up trying to police an un-policable situation. Keep in mind that a set of race tires aren't radically more expensive than Street Tires (sometimes cheaper) and they are available to everyone. So why create another layer of bueracracy for something you may not be able to stop anyway? The solution was to encourage the creation of Novice classes to accomodate the more casual participants.
Some Regions do run a "Treadwear 300+" Stock Class, but they're generally undersubscribed and haven't caught on. Usually the auto-enthusiasts who are casual autocrossers tend to have a handful of inconsequential modifications to their cars that bump them out of the Stock classes anyway. Perhaps the SCCA needs to create a Treadwear-restricted casual class for cars with mild modifications on them? Nothing major to the engine itself, just common things like Cat-back exhaust changes, CAIs & appearance items like spoilers and body kits.
Hmmm, wait a minute....

When did the "200 treadwear for ST rule" get changed to 140? /Quote
When a couple of tire companies pushed a bunch of well known competitors to petition the Solo board for the change (the argument was that the 200 number was just outside the popular 'performance' range and therefore less attractive for manufacturers to support.... which was kind-of the point of the original 200 rule).

Not so much to attract them to the event, but to get them to come back after trying it once (and losing to the serious people).
The original STrules were meant to philosophically parallel the Touring/ShowRoom Stock -> Improved Touring concept from ClubRacing. At least one draft of the original ST/SM rules excluded the classes from running at the Solo Nationals to try and keep the class more beginner friendly (just as Improved Touring is excluded from the Runoffs). Once the classes attracted a bunch of people, that rule ended to 'better server the membership'.
Right now a former Subaru STU front-runner has acquired a BugEye WRX (the lightest body) and is updating the drivetrain/suspension to 2009 specs (better power & geometry). Not exactly what you might call a 'casual tuner' that needs to be accomodated...

Worse... they're written via a democratic membership-driven process.
For the record, the writer races a F500 in Club Racing.
