i think the 7.5 x 16s come in an ET20 mate, so check out if it will poke out the arches to much. the 7s i think coming in the ET28 or 30 iirc they are also available in 15s too
steer clear of 7x15s as they will just look pants.
i was considering these for my escab mk3, good replica wheel
but go for bbs rs's if you can
