i was quite suprised considering i had 2 new front tyres fitted about 3 weeks ago and had the tracking done at the same time.they said it was out so they adjusted it.i wasnt quite happy with it tho to be honest as the steering wheel wasnt centred, anyway you have to have some element of trust dont you, so i took it that it was right, anyway i was having 2 new tyres fitted on the rear today so when they put it on the ramps this is what the tyre looked like

you can imagine my shock when i saw what it looked like! as it wasnt as bad as that when i looked 3 weeks ago.
so.....i took it to get the rear checked over and hopefully adjusted, and whilst they were looking they checked the front.
they had some very up to date infra red equipment, and this showed that it was miles out.

(i dont fully understand what they all mean other than when its in the green its within the tolerances) some of them couldnt be adjusted.they did the toe in/out but said they couldnt do the caster/camber. see sheet below.

thing is who do you believe?? you take these things as being right when someone proffesional does something dont you dunno..
