I just got my control arms. From my research the top will shoot in the fender and lower part will extend your track width like someone else previously stated. I'm installing them on Wed this coming week.. I'll let you know..
The rear ones only make the suspension stiffer from the bearing instead of bushing. I have customer toe arms to increase camber in the rear..
However, my car is lowered 1.5 on springs and the fenders are rolled and pulled..
I'll post photos once it is completed if that helps..
