It drives really well high speed our speed limit is 110kmph on most of our highways and there very high head wind due to the massive trees both sides so your always driving in a wind tunnel (basically) and it's always up and down hills it's never flat . I previously had a fzj80 93 GXL with a 5 speed 1fz Petrol and it didn't have a visor but when I installed a roof basket (cargo rack) it definitely could feel it when in 5th gear and at 110 like it would start to back off and sit on 100 with 35s but with the HZJ80 I currently have now being diesel and turbo the torque is just insane it doesn't even feel head wind even towing a car trailer you definitely can feel the visors catching wind a little bit when the wind hits very hard on and off but doesn't seem to affect the speed or how it pulls , I would say you could probably mount the visor higher up to make a bigger gap at the top but I like how it sits it does get wind noise unfortunately but nothing too bad .
