Ashy - definitely an issue if your measurements centre to centre are correct, and looking at the pics they look weird. Most likely is a bent wishbone mate, they used to recon a second a lap after curbing at brands.
There is a couple of mm play in the bottom ball joints, and you will be able to get a few more on the strut top bolts (where your brace sits).
if i were you i would take the time to do this:
Get a large level bit of tarmac (check with spirit level) - a workshop is usually good.
Get a long tape measure and some chalk and a decent straight edge
Mark out all 4 wheels on the floor with a straight line (use a long line so you can measure toe in and out for each wheel)
Remove the car and then use a set square to work out which wheel is out and investigate.
Hope that helps mate, pm me if not clear ...
