These work perfectly on my small cars (Toyota Corolla XSE and KIA Forte GT-Line) that only have just over 5" of ground clearance. The rubber pads on the bottom keep them from slipping but they are light enough to easily move around.

I needed some ramps to get underneath my car to do general inspections. My car has wide tires and is quite low. These ramps worked great. The ramps are long and the approach angle is 9°. The splitter on my car is low and the car went up the ramps no trouble at all. My Tires are wide and the ramps had more than adequate width for my car to sit on the ramps. A bonus is when the car is sitting secure on the ramps the rear half can be removed to allow access under the car from the side. My car is light, but the ramps are very sturdy and could quite easily take a car weighing much more.
