Long story short - went to pay 50 quid to have the alloys swapped over and a wheel alignment. Ended up paying nearly 700 quid!!
Seems I had a duff set of tyres too so ended up buying 4 x 225/40 Eagle F1's as well, eek!
Here's a cople of pics with new wheels on. They have a hint of lue to them which I was not expecting by tons better than the mcujk that was on them before!
