Those wheel ramp things for raising a car

I've have the Rhino Ramps. Held my Magnum R/T, WRX, Mazdaspeed6, Escape, the GTS, and my Escort GT. Once a car goes on I inspect things to be sure they are safe. If you worry throw a jack stand under too.

I'm smart enough not to use them on the F-150 with a 700 lbs 460 with a Dana 44 front with 33" tires.....but I can crawl under that without stands.

The quality plastic ones work well if used cautiously.
