Hi ive took the plunge and ordered some new suspension going to fit it my self but not 100% sure what im doing with setting up the ride height etc or whether or not ill need to re-index the rear beam.
I've had a look at the clarks garage guide and it looks like it may be too big a job for me to do.
I will either man up and do it or take it to a garage so my questions are:-
I have heard good things about ph sporstcars does anyone know there labour rate?
How long it takes roughly to do the job?
know any other specialists reasonably priced near derby?
 
If your capable off doing the work your self, u could just free and then nip up each bolt again. This would save u labour rate.
 
my offside has sagged slightly would i be able adjust this out using this method.

Iv'e not dealt with a torsion beam before so apologies for the newbie questions. all my knowledge has been gained on ordinary struts, leaf springs or inboard suspension with double wishbones much easier to deal with.
 
You'll need a special tool, which if memory serves me right, to set up the rear suspension correctly. It costs about £7 from an OPC.

My 924s is my daily driver and is maintained with Simon at PH sportscars, but they don't do the cornerweighting/fast road set up.
Labour rates are very favourable, and Simon is OPC trained when these cars were brand new.

After all this work, I'd be tempted to get your suspension set up by contact Chris Franklin at Centre Gravity, -Pricey but done absolutely fantastic, no discussion- or if you'd like a good 4 wheel alignment for porsches:

For a porsche, and its 3 way adjustment at the rear with that tool, you are looking at about £70. Centre Gravity might be a bit more expensive.

The torsion beam rear suspension on our cars is a very simple set up. It's not difficult to understand how it works or even how to set it up. However I would not recommend trying to set it up yourself. Take it to some one like center gravity and have them set it for you.I have done a lot of torsion bar rear ends on Air Cooled VW's ( they are all basically the same) and even I will take my car to a suspension expert to get the tow camber etc set on mine and I have the special tools.What I don't have is a laser alignment machine.
 
ph use Nottingham alignment in basford for geo work.

a lot of alignment places don't like doing the rears on a 944 as they are a bit different and can be seized. you might want to ask simon to check and free up the spring plates.

what suspension are you fitting? unless you want to go low, I'd hope you can just set ride height without re-indexing. (going there is going to increase costs significantly)

fitting new shocks all round is relatively straightforward. you're more likely to need to reindex the rear if your new shocks have helper springs.

Andy Watson has a thread on here recently where he's fitted some spax.

 
Its just a spax psx kit so springs and dampers so i probably wont need to go the whole hog but i am thinking of re bushing the whole thing at the same time just so i know its good. But the powerflex diagram arent exactly clear which bushes are which?
 
Powerflex do not do all of the bushes for the rear. I replaced as many as I could with powerflex ones and then had to order delrin bushes from paragon in USA. ITs a pretty big job, I did it on my car myself. Setting up the torsion bar is a nightmare. I indexed mine wrong twice before getting it right finally. MY car is easy to re index thanks to the holes I bored in the sills. I think it would be a fairly substantial bill to rebush and re-index the torsion bar, definately put it to a specialist as a regular garage may well get it wrong and end up taking longer.
 
Further to what Sandy has said, I might be tempted to take a re-indexing job to a firm who lots of experience doing this in particular.

If I wanted the rear beam removing and re-bushing then Id ask Simon to do it, although he wouldnt be full of enthusiasm (its a crappy job). If I wanted it re-indexing too then Id speak to EMC.
 
..maybe first of all ask ph to see what state the bushes are in (as far as they can see). Just fitting new shocks & front springs, adjusting the rear spring plates, geometry re-set isn't a huge job.

you can either make this a minor job or a really big one...(while the beam is dropped, might as well do fuel and brake lines...)

With all the bushes and lines, there's a lot of ££ in parts, notwithstanding the labour.

Joe,

Have you checked your front struts to see if they are de-mountable in order to fit the Spax dampers?.

With the PSX kit 30mm lowering all round, you should not have to re-index, I am not 100% sure but I don't think you will even need to adjust the ride height via the trailing arm adjuster's, there was no instructions with the PSX kit I had to send back, but with the RSX kit I ended up with there is an instruction to adjust the trailing arm to it's lowest setting.

 
If you were closer I would help you to do it and then you would just have caster camber etc to get done by a pro.
 
Thanks for the offer though and as far as i know i get the whole strut damper and spring in the kit is this not the case?

Hi Joe,

Sorry to say no, that is exactly what I thought please see my thread - Suspension Advice, cannot link for you as on iPad, PSX kit consists of 2 front damper inserts, 2 front springs and 2 rear shocks.
 
Ive had a quick look and couldnt tell if mine are the threaded ones or not but have ordered a couple of caps for it just in case hopefully all will be well
