Aerodynamic aids on Cobras

[coyled]

Bevan, going down in rear spring rate might help your traction problem. I went down in my(660hp) rear spring rates and it helped the hook up off the corner. I have spoken with a few of the shelby spec racer builders when I was thinking about the splitter in front. I had a high speed push above 80 mph corners. I was told to tape off most of the front radiator air hole instead. They saw more improvement from that then the splitter. It did seem to help a few months ago at road america. If you think about it, the tape was a cheap way to go with no down side as long as your motor does not overheat. Next time out, I am going to tape off more of the opening. I did about 10 inches of taping on each side last time. I have seen Bob Bacon's cobra at Harrison's auto dynamic s in Phoenix. It started as a hi-tech but as you can see is more of a can am car today. Chris Harrison did most of the work and is a great guy as well as a suspension and aero expert. I think he runs it in the gt1 or gt2 classes and does quite well. For you ford BB lovers, it has an aluminum 427. Scott
