Sadly it seems all Leons suffer with this when lowered a lot. A minimal amount of lowering is fine, but when you enter coilover territory and drop it more than, say, 40+mm the wheel appears to be too far forward. If you look at pictures of Leons that have been lowered by more than this sort of amount, most if not all of them suffer with it.
Cheers Rob, I had never noticed that before!
