Jacking up a 911 S Targa

[Breeang]

How come that when I tried to jack up my Targa to change a flat tire,using the jacking point, the rear wheel on the side being raised did not quite leave the ground.(Yes it was the rear wheel I was trying to change). I was on a concrete slab with a slight incline downwards towards the front of the car.Was I having a really bad day , or has anyone else noticed this?. I changed the wheel eventually by having my wife sit on the front and 'see-sawed' the back up. Probably not a good idea but it got us back on our way.

What year car? Not that this should make a tremendous difference, but just curious. What type of jack are you using?

You can get the jacking plates and use a normal jack with more throw/leverage.

I had an earlier targa (1972) with an indented floorboard and I experienced the same problem, along with some other ones from the dents. It turned out the problem was rust and the jacking points were not in good shape allowing them to flex when using the factory jack. My drivers side never raised the wheels far enough to allow me to change them. I replaced the floor and all was well.

Hi Mark, it's a 1977 and I do plan on getting the floor replaced soonish,( some rust and pinholes), the 'head scratcher' is that the front wheel came way up off the ground. Thanks.

Could just be the weight of the engine causing the car to "sag" toward the rear. with no roof, that would be my guess. Try measuring the distance from the windshield to the targa bar with the car on the ground, and then with it jacked.

SAGGING ?, I don't like the way that sounds, but thanks for the idea, I'll check into it.
