Rear Center Jack Point.

[Mijostyn]

The 997 cars have a bracket at the rear of the engine block, dead center of the car to be used to jack up the rear of the car. This makes it much easier to place jack stands. I have been under the standard 991s and now the Turbo S 991 and there is no such bracket or obvious lift point. Does anyone know if there is a way to jack these cars up at the rear? The rear edge of the oil pan maybe?? Or maybe Porsche does not want us working on our cars any more?

Jacking by the engine (or oil pan) is NOT recommended) as you put a lot of stress ont he engine mounts that way.

I have not seen anything official from Porsche on this yet.

There is an engine cross member/engine carrier that I would use - that way you are lifting by the chassis not the engine (mounts).

The 991 uses similar jacking points to the 996 under the side rocker panels. The jack pad mounts accept the same pads we use on the earlier cars. I also have not seen anything "offical" concerning other ways to pick the car up.

I saw that cross member. Unfortunately, in the Turbo it is blocked by plumbing. There is another cross member that looks pretty sturdy in front of the engine. I do not think a floor jack can reach it. The oil pan is a beefy cast part and looks pretty tough. Some one is going to punch a hole in one trying. The thing is once the front is up the rear of the car is partially counterbalanced by the mass hanging out in front of the jack stands. I am always surprised at how easy the rear end goes up. I can't believe Porsche did not give us a way to get the car up on stands. I will try to dig into it further and will report back if I find out anything.

Just an update. I jacked the car at one of the rear lift points high enough to put stands under the front lift point and the rear suspension cross memeber under the inboard knuckle of the lower control arm. It seemed to handle it just fine but my mechanic says not to do this as it is not strong enough. He recommended Jackpoint jackstands which were designed by a lawyer/911 buff. You have a large diameter jack pad which fits on your floor jack. You lift the car with it then lower it on a stand which fits over the end of the floor jack. The jack pad locks into the top. Great idea not such a hot execution. It will only fit over very narrow floor jacks which mine is not. It is only 12 inches high and the height is fixed, nowhere near high enough to get my belly under the car not to mention my swollen head (steroid induced). One pair costs $300 but you only need one pair as you can use standard stands at the front. Mine do not even go down to 12 inches.

Back to the drawing board.

Got a photo of what this looks like for future reference?

Take a look at this

Rather expensive, and I can see what you mean about the height limitations.  Might be good for some simple DIY projects, but not for a shop or any serious driveway work.

[Mijostyn]

Actually, I can make that! Any height I want. I will report back in a few weeks with the result.

I put the car up this weekend using the outboard ends of the rear suspension cross member for the rear jack stands. Using padded ESCO jack stands there was absolutely no damage to the cross member, not even a nick in the finish. I even had my wife in the car. You have to have the engine running and someone standing on the brakes to get the wheels off (center lock). The car will corner past 1 G which means that cross member has to be able to handle the weight of the car SIDEWAYS!

It is plenty sturdy. I should have taken a picture. Will do next time I have it up. I have seen the question of getting the 991 series up on jack stands in several forums without solid answers as nobody wants to risk breaking a car.
