Darkside I'm curious to learn here, so if you don't change your shock oil, springs, camber, caster, roll bars etc between the two classes then specifically why would I have to change my ride height to move from VTA to USGT with the same car?

What is your VTA ride height and what is your USGT ride height?

I can only guess that with the higher speeds of the GT class that you would get more chassis roll (with your same VTA suspension setup) thus need a taller ride height to keep from dragging the chassis in the corners. Does that sound right?

Thanks for your input as I would like to run my VTA car in USGT someday too.
