I used one of these I had sitting around and it worked fine* on my CT5 using a floor jack.
* I had previously shaved part of one side of this thing to clear the sills another car, which probably improved the fit, but I suspect it would work right out of the box - plus the two/four packs are comparatively cheap as dirt.
