That's hilarious! Downforce on public roads? Who are these people? And what kind of public roads are they using, safely, to experience variations in downforce? Gimme a break!I recommend keeping your 675LT until after driving a 765LT. Everyone has a different perspective of what constitutes ‘different enough’ so only you can make that decision. I’ve come to learn that many users on these forums sense things that I don’t (ie. downforce helping grip on public roads).
