Some Rules Changes for Daytona: NASCAR on Friday issued a four-page technical bulletin to all Winston Cup teams outlining several changes that must be made to cars for next month's Pepsi 400 at Daytona International Speedway. The most visible change is the requirement of an additional rear roof air deflector, which will likely slow the cars slightly as well as help keep them stay grounded should they get involved in an accident. NASCAR recently conducted a wind-tunnel test with a third roof flap and discovered a change in the air deflector improved the efficiency and performance of the two flaps currently in use. Several other, minor changes were outlined in the bulletin, including rules mandating the height and thickness of air filters, quarter panels, and the fuel cells.(ThatsRacin.com)(6-13-2003)
I am just guessing that the deflector will be exactly the same as the ones that are on the sides of the roof, but on the back of the roof. This will make it just a little box ontop of the car with the front part missing. If it works that will be great!
