Twinspin327..... Back in the 1940's there was a guy who mounted his roadster body on backwards and ran El Mirage... Recall is a little fuzzy, I was too busy laughing as I kicked the slats out of my cradle.. No, Just kidding about the cradle. But you know what I think he either had top speed or set a record.. Better submit that question to the racing organization you plan to race with..to check on the legality.. But as Kilgore said , WHEN you spin, hell , you will look OK to the course workers and can keep going,but don't forget the rear view mirror.. Mike R.
