how much of an alignment specialist is this company?
not doubting they know their eggs, just wondering if its worth giving someone like chris franklin a call (centre gravity)

Rather than it hitting something with the rear, maybe the suspension damage could have been caused by the car falling off a jack while the wheel was off?
I wouldn't want to spend money on fitting a new trailing arm in the hope that it would fix the problem. I'd go to someone to have the chassis alignment checked out first (e.g. Ninemeister). If it then turns out to be a bent trailing arm, get a used one from a breakers. I am sure there will be plenty about.

I know that a decent knock/crash can bend the trailing arms, mate of mine had one fitted on his RS after a smash.
If the trailing arm is knackered, try one of the breakers.
Douglas Valley is advertising loads of 964's for breaking, you should be able to pick one up for a lot less than a new one.

Take the car to a shop that has a Porsche-approved frame bench. They can make some measurements and determine if there is frame damage. If not, a new trailing arm is a small price to pay to sort out the car.
I know this is too late, but a warning to others: always get a 4-wheel alignment check as part of a PPI.

"...(This company have worked on thousands of Porsches since the 70's and have never fitted a trailing arm.)! ..."
That is a little hard to believe. In almost 40 years of Porsche work, they've never removed / replaced a trailing arm? That may well be why they are scratching their head abt what's wrong. I'd consult a P-car suspension shop before you spend any more money...

TD,
Last June I experienced what should have been a minor ding at a track event here in the states. Due to my fantastic luck, I managed to be in exactly the wrong spot, and long story short, ended up snapping the right rear trailing arm completely in two. A very reputable shop did the repairs, but when alignment time came, they could not quite get the full range of specs.
After A LOT of investigation, it turns out I had ever so slightly tweaked the mounted point in the chassis where the trailing arm attaches. Trust me when I say that it takes MAJOR effort, AND EXPERIENCE, to "adjust" this hard point on the chassis; it simply is not supposed to move.
Ultimately, if you feel your chassis mounting point is not in spec., I highly recommend you find someone with a Cellette table (or similar), and the appropriate jigs for the 964 tub, and spend the time and money to get it right the first time. I would imagine Ninemeister, as mentioned above, is a great place to start (although I must acknowledge I have never worked with them, and don't know how convenient they are for you).
By the way, be very careful buying used trailing arms! Ask me how I know...
Good luck,
Dave
