I need to find someone to setup my camber and toe in, check the ride height & shocker settings and adjust the steering rack height to make sure bump steer is minimised.

though i do most things myself I dont have an undercover working area, a flat bit of ground or alignment guages plus everytime ive tried so far it starts snowing or raining. It's mainly for normal road use so won't warrant an expensive racing setup.

Are places like tyre centres worth trying for this sort of work ?

I use andy bates at AB performance. He knows his stuff 01449 736633 he will do a full geo and corner weight

That's reasonably local to me - roughly what sort of price for a full setup?

Procomp charge £225 for a whole day setting up.

Thats check and set shocks and springs
geo setup
corner weighting

Not had it done myself yet (booked in for a few months time) but just searching on will tell you its the best money you can spend and Procomp know their stuff.
