Off the top of me head - no, the shafts look like aftermarket jobs. But can't remember if they are different diameters.

Main way I tell is the very top of the shaft that sticks out in the engine bay. 2 sided spanner holding thing = orginal, hex=aftermarket.

Why worry, OEM are rubbish, don't last and likely need replacing anyway. Decide by the state of the suspension not what make they are.

My rear adjustables can be moved by hand, they are dampers, not shocks.

They are however still likely useless for racing, they've come from a drift car ;) Dai does some custom dampers for the front and rear of our cars, as well as the recent Koni run in Europe that may work out cheaper for you.

What do you think the difference between a damper and shock is? Do you not mean 'it is not a spring'?

My new pressurised KYB monotubes can also be moved by 'hand', but I have to use a fair bit of force to overcome the gas pressure and damping, of course this is nothing compared to the weight of the car. So while gas pressurised shocks are 'springs' it is insignificant.

On the other hand my 940 originally had 'nivomats' which are a self-height-adjusting gas spring+shock but work with the coil spring.

I count a shock absorber as a device/system consisting of a spring and damper, i.e. everything that isn't mass when calculating the Q of the system, (My mechanics is more rusty than my electronics atm, but Q={sqrt(Mk)}/d I believe?), not one part of that. I'm not sure what the proper definition is, I'm not a trained Mech.

Spax from memory say in their fitting instructions to "prime" the dampers by hand for 10 or so cycles to bleed any air that has got into the system anyway, which is also the reason they are always supposed to be stored upright. When I primed mine prior to fitting you could feel any lumpyness disappear too, but it'd be rather useless if you couldn't move it by hand ;) When you crank the clicky screw up on the spax they do become difficult to move by hand, but still possible if you've had your shredded wheat.

Mine too, but I think you are incorrect. AFAIK there is no group name for a spring+damper other than 'suspension'. A damper is a shock in my books (And wkipedia etc).
