Hey guys, first post long story.
Started a build of a 73 Duster in 2000. The objective changed during the build and the car that resulted was intended for club racing in SPO, built to the 2003 GCR. Long story short the car is just now complete, but club racing is no longer a goal. It is street legal and I'll likely use it for solo and rare track days.
My question is: The solo rules have changed a bunch in the last 10 years. The car is likely CP legal (except maybe for E85 fuel), but is there not now basically an unlimited true street class running on true street tires? And what the heck is SM? I don't understand this class.
