Hi,
I would also highly recommend the Rutherford upgrade and the whole team at New Elms, they transformed the ride in my car (2009 4/4).
I travelled up the night before and stayed in a local pub. Tim lent us a car the next morning whilst they worked their magic on our car and we visited Haynes Motor Museum amongst other local attractions.
The car is so much more comfortable to drive now.
Cheers
