Anyone here have experience with the "foam" Race Ramps? I tried getting my car on my current steel ramps in my garage and
- the ramp slide across the floor
- the ramp gouged the floor

Needless to say, I was not happy with myself.

The advertising for Race Ramps claims they will not slide on a garage floor. Added benefit is a much better approach angle that will remove the need to put a board in front of my current ramps to lift the car a bit on approach. They also sell 2 piece designs, so the ramp part can be removed after the car is on the top of the ramp. The ramps are rated for 3000lbs. They are a high tech foam, and I can always add a jackstand if not feeling comfortable trusting foam.

I'm considering both the 56" 8" high 2-piece and the 67" 10" high 2-piece. The 10" high are also wider but I don't know if that is an advantage (more room under car due to height) or disadvantage (less room under car between ramps due to width).

So, anyone use these? Thoughts? Which style do you have?

Thanks for any feedback!
