Well guys its now down to weekly visits, the fronts run out by 15-20 grams at about 300 miles and they are 'round' tyres.
I've also changed front and rear discs to get rid of bad vibration under heavy braking and 'hunting' under very slow braking. £600+ later and the problem's exactly the same, although the rear off side hub is very slightly out according to a micrometer that was put on it.
Any ideas to solve these two problems before I bail on this car and go back to reliable Italian pedigree?

Chris, this is the strangest phenomenom I've ever heard. Once balanced I've never had a wheel go out of balance on any car. Would it be worth trying a different set of wheels for a week? I have a spare set you could try - PM me if interested to make arrangements.

Hi Steve, I know weird and bl**dy annoying! Like you I've never come across this problem on any car I've had. This time it gets balanced I'm marking both the weights and the tyre for slip as well as re inflating them. If it still plays up I'd like to take you up on the wheel offer. Where in Cheshire are you?
thanks
Chris

Chris,
Out of curiosity is it another 10-15 front and 30ish rear that is having to be put on each time or is the out of balence moving around - if you see what I mean

Check this stuff out. I used this on my son's Austin Mini that we were having a problem balancing his tires
(145-100) It worked great and I've added it to the wifes MB and I'll use it on my SC when I replace my
tires.

NOTE
Magnum Plus is not recommended for balancing high performance tires.
This thread is as enticing as the dropped clip in the engine.
Dying to see the answer.

While not related to tire imbalance, have a look at your front control arm bushings. When cracked or worn, which is quite common, they can present as a tire out of balance condition. Seriously.
