...for FE, you want the spoiler to be "neutral", that is, neither creating UPWARD nor creating DOWNWARD forces, just "continuing..." the uninterrupted air flow.

...for road racing, it's all about DOWN force.

It's a spoiler, not an umbrella.

Judging from the pictures the wing is fine as is. There may be more to gain by adding a small air dam and cleaning up the the under body. Consider adding some clear plastic to the side mirrors to smooth the air flow. Tuft testing on a four lane early on a Saturday morning with a video cam will help.

i will have to wait until i can get my brother to help with the tuft tests. i do think there is area for improvement on the front and bottom of the car. im still looking at what kind of tray i want on the bottom( just engine or full car) . and what kind of grill block to use the lower opening is curved around the sides so it wont be to easy to cover the foglight grill area.

new ideal though how about using the spoiler mounting bolts for attachment points for kammback to completely match the template. after the grill block chin spoiler or undertray install. thanks to all for the advice.

Okay, I can agree with this.
