tyres are reasonably new so camber, if too aggressive, may not have had time to leave it's mark
The old tyres would give the best clue....
Very true indeed Chris, and something Dan will have to keep a close eye on.
Having camber checked by a competent technician would certainly do no harm, but it's the incompetent ones that worry me, they could ruin what appears to be a perfectly good setup (not withstanding what Dan is seeing, or thinks he is seeing)

Yeah, by nature they will want to adjust something to get money in the till. Get a free check and report back I suppose? Recommended camber is minus 1 degree 10 minutes plus or minus 0.10
So anything from 1.20 to 2.45 or more needs setting more vertical. If adjusted, by nature the toe will then need setting as well to compensate. So two adjustments in that case.
Depends how they charge. Wheels in motion have a flat fee, some others charge by adjustment, so if caster is out the whole subframe is moved, so camber has to be set to that, then the toe, and if the rear is out that's 4 adjustments which could add up to £100 odd depending on pricing.
Wim in chesham charge a flat rate of 70 with oof discount at their head office only. Pays your money, makes your choice.
Personally I would get it looked at the very least, usually saves money on tyre wear.
