Review on Low Profile Plastic Car Service Ramps - Discount Ramps (2 Pack) by Jack Malloy

These are very light weight one piece plastic ramps with a low profile and tire contour on the top level. I bought these to better place my Toyota 86 on a 2 post 4 arm hydraulic lift without having to use a jack to raise the chassis and place the armrests under the jacking points. My initial experience with them immediately raised safety concerns as my rear wheels threw two rear ramps about 15 feet away from the car. The light weight and lack of rubber pads or feet on the underside of the ramps give little to no "stamina" to keep them in place even at the lowest throttle with an automatic transmission. If you had a standard gearbox it would be even worse. I'm going to make some Z-profile steel brackets that can be bolted to the concrete floor and rise up about 1 inch at the bottom of the ramp to prevent it from rolling under the rear wheels and out. The problem is that it's very hard to feel when the tires are centered in the slightly concave "well" tire at the top of the ramp. Very easy to drive/walk over the end of the ramp. I will also be making a "P" profile steel wedge where the "P" base will be glued and bolted to the front of the top of the ramp with the top loop facing the rail as a stop. Otherwise they are designed and built to be strong and durable enough for my 2700 lb car.
