08. Strickler races this car in races at many different tracks and under many different sanctions, so it races both with and without a spoiler. But if you regularly race without a spoiler, extend the sail panel all the way to the rear of the car if the rules will let you. But if you always run a rear spoiler, shortening the sail panel at the rear will help more air get to the spoiler so it can generate more downforce. Since Strickler races both, he went with the long sail panel.
