Have a look at the WIM trusted centres HERE if you had used the link posted earlier by Steve you would have found this :D
Had my geometry checked at this place recommended by Mr Morse Nottingham Car 4 Wheel Alignment Ltd I went to the one in Colwick.
They found my rear cambers were well out, the lexus dealer had moved the tyres which had gone Bald on the inner edges to the front pointing towards tracking. This is a car which was 13 months old, so it was set incorrectly in the factory. I had 4 new tyres fitted at the same time, not a mark on the rims :D . I would recommend these people for tyres, time will tell on the Geometry. I will post the printout when I get chance.
