20s
Your gona get a lot of kids saying that it looks dumb. I know people that have run deep 11's on 19's. 20's are possible but your gona start to lift the car up. Do what you like.
I really haven't seen any nice racing 20's. That size is mostly the bling rims. I'm looking at 19's and the tires are very reasonable. 275-30-19 there are about 5 tires from $150-$200. Not bad at all.

I drove a 2000 something Crown Vic the other day with 20's on it. It had 245/35/20 tires which I believe is 26.5 inches in diameter. It was like floating on a cloud. I couldn't believe the ride was so smooth. I went over a few potholes at slow speed just to judge the harshness there and it soaked them up no problem. I swear it was just like the factory ride quality. I know that car has a very soft suspension, but I still couldn't believe that a sidewall that short could ride so smooth. Maybe with the right spring rates and shocks it could ride fairly nicely on an f-body as well. I think I would still go for 19's though.
To help out this thread I'll post all the pics I have of cars with 20's on them or at least look like 20's. Some just have 20's on the rear. Man, I've collected a lot over the years.
