Yep! I find it to be very accurate and extremely helpful - especially for setting toe. I also use it for my TC (it is also meant also do 1/8th scale cars).

The only "bummer" thing is that the system is very wide since it is meant to also work with 1/8th scale cars. So, whenever I want to use it, I have to rotate my pit board 90 degrees for the system to fit on it. That's not that big a thing except my pit space usually gets a bit messy so I have to shove things to the side to get the board to fit sideways.
