I jack up the rear on one side, put both Jackpoint stands in place on that side of the car, then do the other side by jacking up the rear and installing both stands. It's pretty easy and quick.

So you only use one floor jack on the rear of the car? It sounds easy. Any concern about the car sliding laterally when one side is jacked up and you're jacking up the other side? I think that's my biggest concern having not seen this procedure before.

That's it. I have not had any slippage at all. It just pivots up.

I have 4 jackpoint stands and use those when switching out the summer/winter wheel sets I have.

I read the idea about jacking up the rear on both sides first and then moving to the front too but the first time I tried it I see exactly why the one side then the other is probably the right answer...

The newer cars are so stiff that, if you get a rear jacking point high enough on a jack to slide the jackpoint stand under it, the front on that side of the car is off the ground by a good amount already! I had no wish to switch to the other side of the car and try jacking up the other rear before doing the fronts once I saw that.

The only tricky part going side to side is that the third point you jack up (opposite rear compared to where you started) is a little hard to see the lift point under the car -- I have to get right on the ground and get a good strong light under there to see and line up the puck and the lift point hole. But that's only a little harder than lining up that first lift point really.

Good luck!

The lift bar looks interesting....

One tip - if you engage parking brake before jacking it up, the risk of slippage is reduced dramatically, basically to nill if you lift one side and then another, so that at least one rear wheel is touching the ground. It also makes torquing rear CLs easier (parking brake holds the wheels well enough).

Personally, I like the look of CLs, but I do find them a hassle to change. I'm a little wary about using the breaker bar and torque wrench around the car. They are very heavy tools and I'm concerned about what would happen if the tool slipped off the CL nut.

Another concern is getting a tire repaired when you aren't near a Porsche dealer (not unusual here in Nevada). Would a tire shop have a 3/4" breaker bar? Not sure how common these are.

You definitely need to be careful with the tools - I'll most likely put some kind of protection over the door next time I do it. Even something as simple as a towel hanging out the window over the door would help. I try to keep the wrench away from the door as much as possible.

A flat tire is certainly an issue to consider. Centerlocks are definitely more difficult to change than 5-lugs if you don't have the right tools, and most independent tire shops don't have them. Many people carry a tire repair/plug kit to address this situation.
