I am not 100 % on this, but pretty sure that the super sideboard is a symmetrical rectangle, built to provide the maximum surface area allowed by the rules, while a standard has a bit of taper, smaller at the front to allow for better visibility. As for the 1degree, I believe that is is built slightly out of square witht the front to the left when facing forward. According to my wing supplier the degree wing helps if the driver likes the car to drive off the LR. People always tell me that there is somehting wrong with my wing when they look straight back at the car. I don't see it, but I also can't hang a picture level.
