'Better' in what way(s)?
Have you considered trading in the FJ on a GT? Probably easier at the same dealership you got the FJ.
Stock windshield sucks. It is amazingly noisy behind it. I don't get head bobbing buffeting, but I definitely got a lot of noise. Just removing it reduces wind noise.
If I'm allowed to say so, FJ-09.org is a terrific resource for owners. They can get you set up with cruise and suspension and 200,000,000 opinions on windshields. There is more talk about windshields than oil!
