The problem with Jackpoint, as
pointed out earlier, is it won't fit under the car on a standard 3.5" tall floor jack on a Model S with spring suspension instead of air suspension. I can confirm this is a problem as my S 60 sits 5.625" high on level ground. Height of jack pad on my Powerzone 380044 3 Ton jack is 3.8”, leaving 1.825" for the Jackpad, which I assume isn't enough based on the experience posted earlier.
Jackpoint sells a 2" floor jack for almost $800 but... that's pretty expensive. So I was hoping U-jack might be a solution, but as I said, it would be hard to find a jack stand that fits it and the Model S and holds S safely.
I contacted Jackpoint and John gave a helpful response:
Hi Chris - we are currently working on a pad for the spring suspension. Until then rather than mill the pad you could pre lift the first corner of the car. That can be done by driving the tire at the first corner to be lifted up on a small board (2x6) or by lifting the car with the jack at the factory lift point without the Jackpoint pad in place. When the tire comes off the ground you slide a short piece of 2x6 under the tire and let the car down. With the tire on the wood there should be enough room under the car to get the jack in place under the lift point with the Jackpoint pad on the jack.
I managed to get my tires rotated with a floor jack and a scissor jack borrowed from a friend, but the scissor was tough to turn and didn't feel entirely safe (I can just imagine it exploding in my face as I'm struggling to turn it) so I hope Jackpoint will have the right pads ready before I need to lift the car again. Otherwise, I can use one of John's tricks or grind down the standard pad.
