My pic was with 4.5" springs and a 1" spacer. With 3", you don't need drop brackets and don't really need that much flex haha.
Also, bent arms do nothing but prevent the 'binding' issue that you have with the control arm bracket. They won't smooth out the ride or put less stress on the mounts. The point A to point B is exactly the same with a bent arm as it is for a straight arm. The forces and stresses on the control arm mounts are in exactly the same direction and magnitude. While that arm is more flat towards the axle mount, it's also more angled downwards off the body side mount. The only way to help ride quality is to lengthen the arms or flatten out the plane that passes through the two mounts (i.e. lower the body mount)
Apparently my arms had the crappy batch of bushings from RE that they've supposedly fixed, so they shouldn't crack like that anymore. I have the RE adjustable uppers too. And honestly, I wouldn't buy anything from Rusty's.
