Just a quick note. The big change for the Super Speedway package is the replacement of the restrictive plate with a tapered spacer. While the function is still pretty much the same, the cars now have a bit more power and better throttle response. To compensate for the power increase, and the increased speed that comes with it, the rear spoiler is now 9". All the cars will also run a 1″ bolt on track bar mount to raise the rear of the cars.
Also, the aero ducts will be used.
Edit: Note the height of the rear spoiler.
