Hello Rusty and FRJDoc,
a question about the need to remove the center pin as mentioned in post #13,, is that slip ability needed due to the car being lowered down on to the DIY slip plates? It seems that if the car was rolled on to the plates the center pin would be a keeper. Asking as I have seen a lot of manufactured alignment turn plates that look to be a wheel mounted on a plate. And what did you use for the center pin?
FJRDoc,, a year down the road anything else you would change?

I am looking at making a set of these like shown in the video and I plan to roll the car up on the plates.

thanks
John

If you lift the car's tire(s) off the center plate for repair or adjustment and then let the car back down, the center pin in the plates keep the plates from sliding perpendicular to the car's center line to let the car return all the way to its static ride height. If the pins are not removable, the plates will not slide and the car will sit to high in the front when you let it down.
