last year holden had new car and killed it Adelaide, everyone alse winged about the carbon fiber roof so all fords swapped to the carbon roof and from then it was pretty close all year, this year mustang is killing it... just waiting for parity to get a bit closer ive noticed some extra downforce at the back of the boot on the mustangs the actual boot lid under the wing has a curve to it like a smaller wing but all other cars have a straight flat off the back, thats also why the mustang hasnt needed as much rear wing as the rest of the field, if it stays as is then its a mustang year 100%
