Removing the FSB and installing a rad support was one of the first things I did on the 2010 and I did it as well on the 13 to get weight off the nose of the car....I am not a corner carver and don't take on/off ramps at high rates of speed so I will be ok.
Greg and I installed mine today. Fits alot better than the stock swaybar did with my techco watts link, cleared the watts just fine. I did notice the slight oversteer feeling when doing some spirited cornering as I have no front swaybar as well. I liked the feedback though, nothing some throttle modulation can't overcome. The strut tower brace in the front def helps pick up some of the slack of the missing front sway as well. Im going to play around with the settings some, I dont see myself ever needing much more than the second hole for street driving.
