If you go for 8x19s you should be fine i'd have though. I fitted 19s and coilovers and wound them a fair way down, how far I couldn't tell you! But you can see in my sig below how far i went. Only issue was a slight bit of rubbing on the front under hard cornering, but a nice bit of round bar soon sorted that out! After that, no rubbng with 4 people in the car.
