I have one car with drag radials, another with Yokahama AD08R's, and may get a set of Mich PSS for a 3rd. These cars can sit for upwards of 6 months if the winter is really crappy (cold temps, snow, and/or road salt).
Have been thinking about some way to lift car up relatively easily, without buying 2 or 3 mid lifts, that are $1400 minimum. Could just jack them up and put them on 4 jack stands, but then there is no way I will jack it back down to take it for a quick spin in winter, if conditions allow.
Was thinking about buying 4 of these

and tie them into some kind of frame (probably just 1/8 flat plate to keep placement of each jack, to each other and aligned to the frame spots I choose). Would tie them together electrically and run them off extra car batteries I always have on charge in the garage anyway. Have to measure and see if 5" is low enough to drive over. Figure whole thing could be less than $200.
