weights on the rims of wheels is wheel balance ... to stop vibration at high rotational speeds ....

Geometry is the setting of all the angles of the wheels to the road so that the tyres run true.

you dont mention any work done on the car that may be related, or how many miles its done. But chances are, with the age of these cars now, most bushes will be close to failure.

rear is only adjustable for toe, camber caster and toe on the front. Your local garage or tyre place wont have facilitys to set the omega correctly, no matter what they tell you.

Full geometric set up needed. However for this to be fully successfull you need good bushes front(wishbone bushes) and back(donut bushes). Check springs for breakages and steering idler for wear/play, and if your happy the front shocks are ok and not leaking get it set up.

You can just set it up without checking of course, but if the shocks need changing at the next mot, or any other related components need replacing, it really needs setting up again once replaced. So best to check first, set up once....

Have a search re set up and bushes. Well covered on here. There are also guides in maintenance for replacment. Hth

Do what I do when the weather's too crap for arsing around under the car-take it to a few different garages where they give you a free quote,when they find the problem ask them to show you where on vehicle.Get a price for parts and labour and compare prices. Work out how long it'll take yourself to do the job compared to labour at garage.
Either way you can't put a value on your life so get an experts opinion and go easy until it's sorted.
Take care

Hi,  No the problem hasnt coincided with the puncture, that was just unfortunate- driving over a couple of nails.  Im thinking that the way the rear wheels are further out at the bottom than at the top,must be the contributory factor.  Ive been out with a spirit level !!!, and the rear tyres are different to the front.  So Im assuming its a camber issue

Why drive to Chesham? Imperial Tyres, Elgin Industrial Estate, Swindon,  have the full Optiline equipment, and have checked and adjusted my Omega geometry, front & rear, for the last few years. Very happy with them.

Cheers

Point taken about experience with these vehicles, can only speak as I find, and as I don't push it performance wise, I probably would not notice slight discrepancies in the settings, which, like yours, are in the 'green'

Can't understand why Imperial said they couldn't do camber on the rear, they certainly gave me different before & after camber readings on the rears in November when they set mine up. Of course they may not have actually altered anything except the readings!
