Probably won't get to that Buttonwillow event. I'm hoping to run the big track at Willow Springs April 22. We leave for a trip to England a few days after so I might be wishfull thinking. The big track at Willow would be the best test for me since the car gets light while turning in to T8 from the back straight. I'm really only expecting this mod to aid cooling in the cockpit more than changing the aero of the car. So any added benefit will be a welcome addition.

whatever you do, don't spin...that roof will last up there for about .05seconds before getting launched into the air (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Hinge the front. And tie a "safety wire" to the back. Or a few safety wires.

Don't want to lose it and scratch the paint.
