UMI's '72 LeMans test car is a road race and auto-x platform designed to showcase UMI's line of performance suspension. With the increasing tendency toward high speed road courses it became apparent that the stock c-clip 12-bolt wasn't going to cut it. UMI's '72 features the new Currie Turn 9 full floater which is bulletproof and gives UMI's owner Ryan Kirkwood a sense of security when hauling into a turn at 140 mph under heavy loading.
