Did you tell them how much you're lowered? The tire also affects rubbing - are you running their recommended tire model & size?
You might find that the wheel doesn't rub if you're at stock height with their recommended tire. If you didn't give them all the info about your setup and follow all of their advice, I hardly see how you can blame them.
