as said, ET15 is spaced further away from the hub, so you'll have no issues whatsoever clearing the brakes/suspension, but you may have problems with the arches, especially if you've lowered it a fair amount and since they're very wide!
Thinner stretched tires can help, but the offset is still rather low you may still have to chop/roll the arches.
Best to get them on and have a look really
