For those of you who maybe do on-site service, or have one of these lying around for personal use, what have you been using/used? We are looking at picking up a set for on-the-fly alignments (in conjunction with a camber guage) at events and what not.
I'm sure they can do what they say they can do, at this point I'm just checking out names. I'm looking at the Laser Toe 2 (I think its called that) setup from Advanced Racing Technologies, and the T-12 from Tru-line, both for toe. Any other suggestions in the sub $2k price range?

 

PCV and a spool of string

 

lol I can imagine rolling up to an event with some string and wooden boards goin "Who wants an alignment!?"
It wouldn't just be for us, but a way of getting accurate toe and camber settings on other peoples' cars as well. From some feedback we got at this year's WTDR Exblow, it seems like there are people at these events that would be willing to take off their current suspension and run ours for a bit to get a feel for them, but can't because of manpower, tools, and lack of a proper alignment. We could provide that to them.

 

Also, 2 vs 4 turn plates: Are 4 plates truly necessary, or will 2 be fine?
