As far as I know, and from what I have read, the b6 and b7 have the same suspension. My coilovers were labeled as b6/b7. So, as long as they are both made for Quattro, you should be fine.
I had those with h&r springs on a previous VW, and I thought it was a pretty good setup. Pretty firm ride and not bouncy- overall much better than stock.
