I'm with Cabrio993, the entire side of my C2S comes up no matter which point I jack from, as does my neighbor's 993. We do both have the same suspension as Cabrio993.

Must be a difference in cars. Mine will only both come up from jacking the rear. Maybe i never tried lifting high enough from the front. Now i just use my lift

I have heard that the white cars are more rigid than any of the other colors.

airjacks, we NEED airjacks....

cabrio993

yes, it is a fact. They had to make them 72% more rigid to accomodate the stronger engines that Porsche puts into white cars.

Okay - I ordered RS mounts and an RS short shift kit. Maybe now I'll be able to jack up my car in peace.

Thanks for the advice and ideas.

Remember this line? It was from a couple of years ago. You just had me LOL. 72%, huh. Stronger engines. Haha, that's awesome. It's in the manual, right???

oohh. you will love the RS Shift kit.. did you get a golden rod? With the RS mounts the engine will be more connected with the car - you will realize how gone the old ones were!

I always jack on the engine case once I have the front jack points on stands.. I think the metal Is strong enough to take the weight for the 30s I have it in the air. Just take your time and pay attention to everything.

I have dropped a car before and almost lost my head (a friend yanked me out of the way before it fell). 10 years later and I am still overly cautious. I use a two jack method, lifting the front of the car first by the jacking points and then placing jack stands under the control arm subrframe.
Move the jacks to the back and lift the rear and place jack stands (with the nifty Harbor Freight Rubber Pads) under the engine/rear suspension sub-frame. If I go very high I may do a few iterations of this to keep the car from being too crooked. It's slow but it's safe for both me and the car.

I understand that a lot of people use the engine to lift the rear. It is convenient but I'm concerned about deforming or cracking the case. It is just aluminum after all. The magnesium cases on earlier models are much worse.

Where do you put your jack on a 993 engine? One side of the case has a lip that protrudes about an inch. It just doesn't seem strong enough to lift the car. And you would only lift one side of the case. Talk about twisting your case. Where else would you put your jack?

There is just no way that the case would not deform at least temporarily under the concentrated stress of lifting the car. Maybe that is a contribution to the frequent engine leaks on our cars. Maybe it is the cause of some of the fretting of main bearing supports that some people have observed at tear down.

I wonder if the jack stand had a rubber insert and if it didn't, a rubber pad should have been used. I'd never place a metal tipped jack stand against another metal part on the car. Those junctions tend to slip.

I don't. My engine mounts are supposed to hold up a percentage of an engine's weight...not a car.

The engine "hangs" on the mounts. If anything, jacking up by the case relieves the stress on the mounts.
