Another YouTube video popped up recently of the 1980 SSC race. Mostly boxy cars (Rabbits, Gremlins, etc.). Talk about BODY ROLL ! ! ! Practically scraping chrome door handles on the track. :-)
It's fun to think back on those days and all the creative ways people were making the cars faster. Lots of competitors with manufacturers helping out with special parts and other assistance. Those really were the days of competitors getting big boxes of stock parts and finding the best ones to use.
Another interesting rule they had back then (maybe still do today in Touring?) - No non-stock paint jobs. Could only use vinyl to make stripes, etc. I guess that was to help the "Race on Sunday, Sell on Monday" aspect.
