Wheel platforms for 2-post lift?

I'm looking for something that I'm not sure exists—or should.

Is there any sort of rail or deck or platform system to allow a two-post chassis lift to lift a car by the wheels, life a four-poster would? It would be awesome to be able to do suspension adjustments while the car was in the air and under load. My lift is a pretty heavy duty rotary. 12k capacity I believe. So the additional weight wouldn't be an issue. Gotta be a reason such a setup doesn't exist (or is at least very hard to find).

Like the wheel adaptors on Mohawk's site?

OH EM GEE

Yeah, that's what I'm looking for. Something with a flat platform and chocks would be more pleasing, since it would put the car at proper ride height, but I could totally live with that. Gotta see if they can fit my lift I guess.

Something along the lines of the Mohawk Speedlane might be what you are looking for:

That is simply beautiful.

Cool, never knew that was an option. I have a 2 post lift too.

How about a 12" high plywood box?

If that could be fitted to a Max Jax, you'd get a lot more clearance under the car. Hmmmmm....

Anyone noticed all the bottomed out marks?
