The Portable Pit Stop car Lift Ramps were designed for car enthusiasts and racers alike, enabling them to get their car up 14" in the air with ease. The adjustable wheel base (from 98" to 111") makes it easy to accommodate a wide variety of cars. The racer's model comes with a cut out section made to fit a 15" scale pad that is 2.5" thick. It also comes with a spacer to fill the cut out when the scales are not needed. The standard model is completely flat and has no cut out for scales. Great as a Car Lift Solution!
