Erm, it may have been mentioned in this thread already, but there is another thread in here by a member called Bloodclod I think.
He made an awesome FWD buggy based on ones that were factory made back in.....the late 80's maybe?
So they have been done and they worked ok, design problems notwithstanding.
eta: as a matter of fact, here it is. Well worth a look see.
