Hardtop or soft top? If soft top, it doesn't take much to change air flow and create turbulence. I put a bug shield on and I thought someone was on top with a bat, beating on it. I had to take it off. Air flow is a strange thing. I know everyone says it doesn't matter with a Jeep, it's a just a big ole square brick going down the road. They are wrong, it matters.
