If you have a large square and a very level floor you should be able to do a DIY camber adjustment.
You will need a square that is the height of the wheel rim, by positioning the T2 on a level smooth surface, place your square at right angles to the wheel and measure from the bottom of the rim to the square and also measure from the top of the rim to the square, subtract the two measurements and you will have how far out your camber is in mm.
If you now jack up and remove the wheel you will see 2 bolts securing the upper wishbone link, behind the link there should be a set of shims that each bolt passes through, by unbolting and removing a shim from each bolt behind the link will reduce the + camber. Make sure when removing shims that the shims removed are of equal thickness because if they are not then removing unequal thickness shims from both bolt will not only alter the camber but will also alter the castor angle.
When removed, replace the wheel and lower to the ground again and re-measure with the square to determine the change in the camber, it will only require a small thickness of shims to be removed to make a large difference at the wheel. If adjustment is still required then you will have to go through the same process again until you have the wheel as near to vertical as possible, a bit of a hit and miss way of doing it but it does work.
You may need some more shim washers to get it precise, say if you only have thick washers fitted and the removal of them is to much then replace with a thinner washer always in pairs.
