Crashed Porsche Suspension Issue

Evening,

Somebody here will know...

I have bought a a crashed Porsche 997, it went off on track and appears to be near side front as the first impact and then down the whole side.
It needs lights bumper wing radiators and rear quarter panel, seat and door airbags. That is the easy fix, however;

The car appears to sit low near side front wheel (rear tyre is flat) by a couple of inches, it is obvious when you look at it

I have jacked up the car and placed it on blocks of wood it is on a gravel drive so not perfectly flat but nigh on.
If i measure hub to ground the two sides are the same
Wheel arch to ground the two sides are the same.
Various positions on the hub / suspension arms to the top of the shock mount are all there or thereabouts.
Gravel drive is small stones set into a plastic grid so there is no sinking.

The shock moves freely using a jack under the hub.
Shock is dry.
There is no obvious damage to the suspension arms, or chassis.

With no weight on the suspension the height is the same left to right once you put weight on it the left appears to sink further.

Any suggestions as to what might be out/broken here ?

thanks

If im reading that correct the rear left / near side tyre is still flat ?

In which case the weight distrubution would shift more to the left side once the car is on the ground which would raise the shocks slightly on the right / drivers side and compress them slightly more on the left / near side.

You would need all the tyre pressures correct or all flat to see if its really dipping on the nearside.

The Good news is that most of what you need is 987 Boxster.
Do you have a specialist nearby ?
The front end of the car is not difficult to work on from my experience with my 987.

Afternoon,

I have fixed it.
Would you believe that if you put air in the rear tyre the ride height corrects itself !!
I thought it had been knocked off the rim but the dust cap had been pushed into the valve and was pushing on the pin, meaning all the air had escaped.

DOH !!!!

It is the third Porsche i have fixed, i did a 993 and a 991 convertible, both had gone off on track days.

Didnt like the 993, due to age some of the bolts were rusty / seized and when it was finished the pedals were so offset to the left
it was uncomfortable to drive for long distances - made a great noise though.

The 991 had 15,000 miles on it and there were no rusty fixings, it came apart really easily and every part has a part number on it

So far the 997 is the as easy to take apart.
Girlfriend said this morning "when are you going to get the quarter panel ? It has been in the spare bedroom for two weeks... Its fairly hard to miss

The Ghibli in comparison was much harder to take apart, a classic case of remove part A before part B, but part B is in the way .....

Thanks
