Very nice! Those are some serious wheels. And no, I doubt you're done.
If I might be a bit of a "hater" for a minute, I think the exhaust tips stick out way too far. I think it looks odd and it could pose a potential issue if you back into anything or if someone bumps into the rear. It could damage your exhaust all the way up to the block. It has happened before although it took a much harder hit in the case I am aware of. Just my $0.02.
