that or go to grab some wood and cut ramp adapters.....? I would buy race ramps if i decided to drop my car tho.
just to be clear, i would buy 2 piece of 4" wide, 1" tall, and maybe 1ft long plank and align it with my ramps and wheels to get on the ramp. if you feel it should be more "secure" you can also run some screws through the planks to the ramp.
I've used planks to get lowered cars onto alignment racks plenty of times and feel this can be a solution for you.
