Well, Mike, GY3 didn't mention CHEAP in his original post, so I just tossed an option on the table that nobody else had mentioned. Many, if not most cars that are set up to run 1/4 mile slow down both 60' and ET when a 'Glide is installed. In their defense, they are usually more consistent, less dependent on track prep, a little easier on drive line, and need less of a burnout, which saves on tires.

So while not a cheap option, it's a valid one
