Thanks to all for this discussion. My road race car is a 91 camaro, and I've been thinking that an aero advantage might be the ticket. The class I run in is limited to a HP to weight ratio. So top end would be better with less drag (of course) and could be a real advantage in such a race class MPG for this is obviously no issue. 5 gallon of fuel burned in a 25 min. run is the norm.
I'm at a disadvantage to a certain degree due to old technology and no ABS compared with the new S197 Mustangs with race tuned ABS.
That pic of the Budweiser Camaro was awesome. I liked the side skirts. Been thinking about doing that.
Anyhow, sorry to threadjack. Cool ideas here. I will likely start a thread just for the racecar to see what we can come up with. For now, I'm gonna keep on the trailer so I can afford to take the car to the track in the first place!
