So after having the steering rack changed and complaining to VW UK numerous times about the steering wheel being mal-aligned, I decided to take matters into my own hands and get the suspension/geometry setup perfectly by an expert.
I went to Chris at Centregravity in Atherstone today and he spent the best part of 4 hours sorting out the 4 wheel alignment, camber, castor, toes front and rear. The experience was superb, apart from being a top guy (who blatently knows what he is talking about), once the car was optomised we went for a test drive and the results astounding. The car is planted at the rear and the grip levels have increased exponentially. The best £160 I spent on this car without a doubt.

P.S. The steering wheel is now perfectly centred and the car will drive doughnuts around a factory setup. You can also ask him to make the back end as loose as u want and customise it as u choose!
