The ramps that I have seen are made from stamped sheet metal and spot welded together. IMHO I wouldn't put a go-kart on them. They provide no lateral stability, and for some cars there is not enough clearance to the fenders so you might hit or move them before you even get up on them. You cannot see what is going on while driving up and as for putting the car down on them after you jack it up prevents you from working on the wheels. If you work under your car and you want to be safe go buy some GOOD jackstands and use them correctly. Properly positioned with the car up nice and high you can even remove the trans. Make sure the floor is smooth and LEVEL. Besides the usual dangers of working on the fuel system, lifting and working underneath the car is dangerous if not done carefully. When setting the car on jackstands be aware that if placed under suspension components the jackstands may tend to move so watch carefully as you let the weight of the car onto them. After putting on the jackstands a good test is to shake the car side to side and see how steady it really is. (Try THAT with your ramps if you dare!) There is no chance it could roll off of the jackstands unlike the ramps. I store my car in "hover" mode for the winter on jackstands and I can inspect and clean it easily when it's time to revive it.
