They will go on with spacer / adaptors. That should also sort out the offest difference as well.
You will be looking at around £100 for a set of hubcentric spacers, so not cheap. I have never liked the idea of them though. They move the wheel futher away from the hub and can cause additional strain on stub axles and bearings.
If you do go for thoughs wheels, I reckon they will go for a fair bit of money, then when you add on the spacers and a refurb, they will probably cost the same as a decent set of ED30's that will bolt straight on.
