4 to 5 lug wheel adaptors, good or bad?

[calimus at techography.net (calimus)]

I'm in a bit of a delema.  For me, I lust for a set of BBS RX's for my
rocco, well an opportunity has presented itself with a small snag, they are
5 lug rims.  Now I know the Potters carry the H&R 4 to 5 lug adaptors, but
are the a wise choise?  Naturally I'm concerned about them cracking or
breaking in any way and I'm wondering if anyone on the list has played with
these.

My only other option would be to bump up to the corrado front and rear discs
and I don't think I can squeeze those and the rims into my current budget.
That is unless someone just happens to have a set for dirt cheap they would
like to get rid of.  Anyone?  Anyone? Bueller?

So, what say the great list on this subject?
