15x8 +25 rubbed on my EK4 that is lowered but no camber adjustment on 195 tyres. 185s and camber and they would have been fine. Not sure if a +15 would though and I have no idea whether them being 16s makes any difference.
Awesome, such a great conversion. Shame they usually cost the earth to achieve. Sounds like you got them for a decent price though. And fitted very well indeed!
