I might be wrong on this, so anybody feel free to correct me. I believe that the reason why they say to use 17 or bigger is due to scrub line issues. In other words if you happen to get a flat in the front, running a sixteen inch wheel, your crossmember might dig into the road. Again I could be wrong on this. Maybe someone can give you a more definitive answer.
I'm currently running a 5/7 drop on my '93 with 16" wheels. I know that if I get a flat, I'm in trouble.
