Number one the rear deck fin was for side drafting the roof fin was supposed to reduce flips. #2 higher the car sits to the ground the less grip down-force. These cars are going to flip dont care what they do as Dale Sr once said. Its a dangerous sport as in any racing is. These are not F1 cars and are not designed to stick to the ground like the F1.
Ever notice you don't get to see the top secret bottles of the F1 unless they flip. lol. But the reason Nascar is losing fans is because people like me who started watching racing back when cale yarborough was my top pick then it was Rusty and Dale Sr. Thats when racing was racing.
Today its to politically correct. Cant say whats on your mind cant bump and run or like Dale Sr would say "rattle there cage" The stage racing is just stupid. Points racing was a lot better. If it was not for the race format Kyle Bush would have never been champion that was handed to him.
The racing is no longer in the drivers hands its in Nascar who does more policing then any sport to-date. The cars will change as the manfactures changes the stock cars. thats been going on since stock car racing. One thing there is nothing stock about last 15 years of stock cars in Nascar.
Bring back the Winston Cup thats when Nascar was great. Yea its a cigarette sponsor so what. lol
