These are the basics in electrical classes. I may have forgotten one.
in past year for TC, a couple of major US races have added 21.5 TC labeling it as stock TC, 17.5 TC as Super Stock. some local tracks are following this trend. seems to be a trend to make 21,5 the new stock (TC wise only)
WGT-R see it also ran as 21.5 and 25.5, very rare for them to go 17.5 as even 21.5 pushes the envelope. only time i have seen 17.5 is when they run WGT foam
F-1 went thru a cycle....17.5....21.5....now predom 25.5
