What is a "touring car?"

[Chip42]

And that seemed to be what attracted a lot of people in the first place. Basically, that there was a published formula for establishing the weight/etc of a given chassis/motor package. And that, as a competitor, you knew exactly what that formula was prior to building your car. Everybody gets the same playbook and you get to choose which knife you want to come to the fight with.

I always looked at the attraction as being an OEM-agnostic weight, a place to run (more) open engines than IT and SM (the major feeder classes) without going prod or GT crazy on the car itself, and the optionto finally swap out that [insert POS engine designation here] your favorite or chosen chassis came with for the awesome one that came in some unobtanium foreign market ride or was misused in some big roll-happy sedan. from the start, OEM head and intake design meant displacement to weight with universally limitted prep specs were going to creat winners and loosers. the same argument can be (and just has been) made for chassis. There are attmepts wiothin the current rules to try and generically bin RWD/FWD, strut/multilink, valve count, etc... with different weight percentages, so it's not being "ignored". The trouble is that when a particularly good 3V or bad 4V head, a very good strut FWD, etc.. show up and poop in the punch bowl. because of the very general weight assignments they unbalance the class. Currently there's no way to deal with these issues on the chassis side. particularly over/under achieving engines can at least get a specline within precedent (restrictors, weight changes, stock cam specs, etc...)
