When I hired in to GMPG, they had a machine in addition to the Chevy VHF in Warren) loaded by pumping water in and out of tanks to alter loads. I also remember a Lotus rig that Jack Turner (r.i.p.) ordered for the Chevy P.G. garage. We really needed Mz compliance steer. AND, the machine came unequipped to do it. What a farce.
Turns out we gave the machine away because no one wanted it. Used for vehicle storage and wheel alignment. As in: Lotus never considered ENF as a player in handling. WTF... From the statistics of their car measurements, they still don't !
