I've just bought a 90 turbo & I've been panicking the back end was twisted from a smash but then I read that the rear quarters are not always the same. It states that the near side wheel can be further out & further forward than the offside. Wtf?! Anyone experienced this crazyness before & can it be remedied?
An oddity for 944 rear end

There was a tech question in Excellence magazine about setting suspension ride height by measuring from the wheel openings. The tech expert suggested that bodywork could be off as much as an inch from side to side so ride height must be measured from suspension pick up points. While I agree with measuring from suspension pick up points - the suggestion that the body work can vary this much (without accident damage) seems pretty far out to me. After all, even Morgan uses jigs to assemble their hand-built bodies so I would expect Porsche to get closer than that in their manufacturing process.

I was told by a certain specialist that one of the reasons why Porsche stopped making the 944/968 was that they could not get the gaps etc. any closer for the customers who were demanding further excellence.
If the above is true it would not be the first car to have such an issue.

Certainly 10mm or so difference in the rear wings is standard. Some 944s with larger wheels need the wheel arch rolling on one side only, I've been told.
Would worry more if a wheel had moved!

i had new suspension fitted to my 964 by Chris at Center Gravity and i complained to him the wheel to arch distances were about 1cm different between the two back arches. he took me through the chassis checks to prove to me the `issue` was with the hand built car and the vagaries of that. how big these tolerances can be i dont know but i was entirely convinced with Chris` explanation and demonstration.

25mm sounds to much pain less gaps are 6/7mm 6.5
It's possible from the rear leg, traling arms to bend slightly if car drifted to a curb in the snow or drifted and hit the curb. There hollow alloy so you would think there crack but this could be your issue.
How's it handle bent rear arm can cause the camber to steer from the rear.
Put a weak magnet on the arch to check for filler mm or so it will still stick more it won't. Your feel the pull strength get less as the filler starts
You could have one wheel with a different size off set to the other? Say 3 front wheels

On my car, the gaps between the rear bumper and rear quarter panels are different between the two sides. I thought this must have been a result of filler bodgery or accident damage, and after completely rebuilding both rear corners I could not find any evidence of either...

When I had the 18"s on, the near side rear would often catch the arch, if you looked from the rear square on you could see the offset plain as day.
16's have no problem though [

I have always heard that they are different - side to side.

It's a very common question and we've had many threads about it so I took this picture over ten years ago to show that the rear wheel arch sticks out 1/2" more on the drivers side than it does on the passenger. You only really notice it when you start to put wider wheels and tyres on, like my 255/40/17s.

My nearside wheel rubs on 17's very slightly but has clearance on the offside

Not really. They were designed with something called a "pencil", applied to "paper". Then they made a mock-up from clay. The aero was designed by looking at it from the front, squatted down, and saying "that looks smooth"....[&:]
The leap from 1970s car technology the to the present day is incredible. Watch The Sweeney, your 944 was designed when TV was just coming out of the '50s!
