For your question of the rear corners of the chassis rubbing the racing surface, it is probably best to get the ride height so that does not happen but... I put a steel 4-40 button head on the bottom of the chassis where it screws into the post supporting the cross brace. It sets down in the counter sunk hole some but still allows the head of the screw to rub before the chassis. Keep and eye on it so that you don't let the button head screw grind down so far that you cannot get a wrench in it to remove it. It would be really cool if we could find some magnesium screws. They would spark when they rubbed. Just like the old formula one cars used to do.
Thanks Crashby that's a great idea. I'm still wondering what CE and OD are up to. Any ideas?
