Winner!I thought they were removing them for a aero advantage, less drag?
they do make a difference, easy way to see this is get a mate to drive your ute, stand up in the tray and then hold the fenders up, and i reckon wou will quickly notice how much drag they actually haveCan't imagine the loss of wind resistance or weight is terribly noticeable. Least I didn't notice a difference, but it could make an impact to those who really need every ounce of performance.
I did it mainly for looks, and I really like being able to easily see my front tires. As for mud/rock protection, it makes almost no difference at all. If theres mud I still come back muddy
