I've recently changed the top mount of my front left wheel and although I've marked it all up before dismantling I would like to have the geometry all checked out again, and have a few questions as a result:

-I have a receipt from Austec Racing for the car which shows ajusted (final) settings that are very different from the TVR recommended settings, would that be down to adjustable Ohlins meaning the settings are now customised to the car and standard no longer applies ?
-What can be adjusted other than Toe and Camber ?

I would entrust it to someone in the UK, but I'm now in France so need to find someone who has the right equipment and who I can tell what to do.

Having different shocks shouldn't make any difference to the geometry settings, having different length springs might. At the standard ride height I don't think it matters.

Toe, castor and camber are adjustable on the front wheels and toe and camber on the rear wheels.

At the front;
Toe is adjusted with the steering track rods.
Camber is adjusted by changing the position of the top ball joint in the slots in the top arm.
Castor is adjusted by moving the shims either side of the top ball joint.

At the rear;
Toe is adjusted with the screw adjuster at the front inboard joint of the lower suspension arm
Camber is adjusted by changing the position of the top of the rear upright in the slotted top arm.

That's the thing, springs are adjustable and I believe it has been corner weighed, so that could explain the different settings.

Think I need to find a proper chassis setup place and not just a kwik fit equivalent.

Very much so - its not something to leave to anyone who isn't very familiar with Cerberas
