[Larry Hill]

The race car we carry on top. On the rear we use two non adjustable straps that surround and cross the center section. If the car is not straight on the lift one of the rear straps will be loose when the front is pulled forward and down. You have two choices re position the car or stop 20 miles down the road and re tighten the front straps. Due to the crown in the road the car always slides down hill, curbside. On the front I use four straps, two straps crossed tied to the Kmember and two lighter safety straps going to two 7/16 eye bolts to limit front suspension travel. After everything is tight we recheck at 50,75,100 miles until lit stops moving around. In the morning when tire pressure is lower retighten the straps.

If you want to limit upward movement turn buckles and pined blocks work. Also we strap down the lift at all four corners.
Try to carry a spare strap for every position.
