Acceptable body flex when jacking?

Hello,
I jacked up my front end this weekend to access the fuel lines for replacement.
I used the factory front jack points with a set of JACKPOINT stands.
The JACKPOINT stands are super solid.
I opened the passenger door very briefly while on the stands and noticed it was slightly "off" when I closed it back gently.
After removing my soft fuel lines I put the 928 back down and the passenger door closes perfectly again.
The door andpanel gap looked exactly the same both on and off the stands.
Is this normal/OK/acceptable/horrible?
Thanks, experts!
Dan

I get the exact same thing when I get the car up on Liftbars and stands. I normally put the car up in the same place on the cement slab in my garage. I get the repeatable slight skew in the driver's door excursion every time. I guess it is a slight off level of the slab and/or the stand. It goes back to normal when it's on all fours.

[QUOTE=Dean_Fuller;11754079] Some flex is expected.
Sounds like a Porsche book title.
Yes normal, my '86 911 flexed much worse than my superior '83S btw.
I like to drive up on ramps when i can.
I place a mirror so i can see where the front wheels are from the driver's seat.

That is directly contrary to the WSM. When I lift the car and need to have the cross member off, I always remove it before lifting, per WSM instructions. I have never had a problem, over three separate sharks following this procedure. It is fine ( obviously) to lift the car with the cross member on, just don't remove it once it's in the air.

I have noticed the same thing, using a two post lift which is supported at the proper lift locations. Just a little flex and the door does not shut pure. I try to not open and close the door if possible while it is on the lift.

I thought I remembered reading it in 928 Tech manual or something else 'official' that said risk of windshield injury. It did kind of make sense too.

Yes this is a normal effect of raising the car, whether it be one corner or all four points on a two post lift. The first time I also was concerned, but the doors always shut tight and solid once back on all four wheels.

Here's the WSM reference: WSM 10-2 ..... " car must stand on its wheels when cross brace is removed or installed".
