Scottrick - Nice call on the set up station. I've had my Unity for 15+ years and it does 1/12, 1/10 and 1/8 cale, packs nice does track width, toe and camber with your race tires inplace. So a set up board to check ride height and you are done.

My older one does have a center line groove, and I've seen new units which have a better angle gage, but did not have the center line.
