Are these as dodgy as their name suggests? People selling wheels with funny PCD's always seem to say they're fine - I know nothing about them, but their name just makes them sound like your wheels could fall off. The wheels in question have are 5x108, my mk4 is 5x100??!?1??!?1?1?1??
8mm might be a bit much for wobble bolts. They generally only take up 2 or 3mm of `slack`. ie; 4x98 to 4x100.
