My experience has been they stick up a lot further then they should. This means every branch that slides over your hood hits them. I have one that is fairly bent up ( I have taken both off a few times to try and bend back to original shape) as they don't take much to bench and on both vents the frog skin that covers them is ripping off from branches sliding over them. They work awesome, i can't complain about that. However if they could build a set that had a lower profile and didn't get banged up from sticking out so far it would be much better in my opinion. I have about three hundred miles on and I need a new set. They work but your better not bump them on anything or they will crumple like nothing.
