We have a 1 piece Glasstek nose that has a nice flange behind the front wheel and a closed lower grille. We also made removable plates to close off the upper grille that stay off during street driving and a chin spoiler. We eliminated the drip rails, side lights and door handles, while adding a pro stock style wing. The tin work closed off the rear underside behind the tires. Also flush mounted Lexan with no window trim and a narrow aero style scoop in lieu of the 6PAK scoop I originally had.

How much difference any of it makes, who knows......but the car is very solid at 8600 in high gear.
