OK, so I went back down there this morning, initially they started off by saying that my car did not have adjustable camber at the front, the bloke then started to talk a fair amount of BS saying stuff like the rubbers on the strut tops have deteriorated causing the strut to bow out which was what was causing the pull, and that the camber measurement was not anything to do with the pull. I was insistent that you can in fact adjust the camber on the front struts and so they put it up on the hoist and sure enough found the camber bolts.

They said they adjusted the right camber as much as they could. So the final measurements are FL +0.05° FR -0.30°. So everything is within spec now but I am still pretty disappointed that they didn't correct the left to compensate for the right negative camber... at the end of the day though they did the job and that is all I can really ask of them.

The pull I believe is gone now, maybe still a tad is there but it is much less noticeable and I am probably just being neurotic now.

I am also dumbfounded that a tyre shop which offers wheel alignments does not think that uneven camber could be a problem especially seeing as their business is to make sure your tyres last as long as possible...

Ah well lesson learnt, I won't be getting a wheel alignment done at a tyre shop anymore, will take it to a proper suspension shop.
