We have and regularly calibrate a Hunter Pro-Align with DSP-700 measurement heads and use it frequently for wheel alignment research.
For example, the two cars below were measured over 800 times.
The data on the dark blue Mercedes includes over 300 measurements over five years.
The black Porsche Cabriolet seen here has been repeatedly measured over 500 times. The green frame was built to speed up the raising and lowering of the car onto the bearing plates.
