Paul,
go and talk to Tim & Darren at New Elms. I lve near Bath and find them endlessly helpful.
I fall into the high mileage class of Morganistas - 15,000 in two & half years. When I mentioned this to Darren his comment was:
"I wouldn't if that was my car!"
"can you fix it?"
"Yes. Leave it with me for a day"

Note: if you're serious and haven't replaced the factory front suspension, do so. Both New Elms & Wolf Perfomance regard this as a given (I suspect SimonH will say the same). Neither of them will touch SSL front end (and two nearby main delaers were unable to set the SSL front end up properly). Darren's solution was to replace it with the Rutherford front end; Cain's solution is very similar.

Miraculous. I toured northern Scotland this Summer and my 4/4 (2013 model) was brilliant.

I've had long chats with Tim & Cain and conclude that Cain is more race orientated - not my cup of tea. Phone them!

If you're a 'Sunday Luncher' then live with it but if you enjoy driving (let's say 4,000+ a year) it's worth paying for the improvement.

If you'd like to meet up to chew the fat then PM me
