Plenty of DIYers do use a block of wood when using a floor jack with Mercedes-Benz or BMW cars equipped with jack points with an integrated vehicle jack pocket. Our customers seem to appreciate the much more elegant solution that our jack pad tools offer. One of the unique features of most of our jack pad tools is that they can be suspended from the jack point rather than just placed on top of the floor jack. Once in place, it is very easy to center up a floor jack beneath the jack point, since the jack pad tool is readily visible whereas the jack point itself is pretty much out of sight. Owners of Mercedes cars equipped with AMG side skirts that hang below the jack points especially appreciate this feature. Several of our customers have reported retiring their wooden blocks. In any case, it’s not good idea to use a floor jack directly on the jack point.
Instead of raising the yardstick until is contacts the car as described above, you can prop one end of the yardstick up to 7.25" high to simulate the slope of any of the ramps with a 10.8 degree incline. Do the same with the yardstick propped to a height of 5" to visualize the car-to-ramp clearance with the more shallow 6.8 degree ramps.

Use our exclusive Google Sheet calculators to take the guess work out of selecting the correct Race Ramps product.
Standard Race Ramps models (RR prefix) work for 80% to 90% of the vehicles on the road. Reverse Logic recognized a need for additional ramp models (RLL prefix) for a small segment of the market. Since 2011, Reverse Logic has built an array of custom ramps specifically for very low ground clearance street cars and ground hugging track cars. The Reverse Logic Progressive Incline service and trailer ramps accommodate very low approach angles while minimizing the length of the ramps as compared to a constant incline design. Race Ramps has adopted some of the Reverse Logic models like the RR-72-2 two-stage incline ramps. Race Ramps has also incorporated some of the features first rolled out in Reverse Logic designs in its standard product offering. Examples are the lower 2" high platform stop and the invertible incline sections of the RR-80-10-2 ramps that double as trailer ramps
