These VOLK toe arms are a double adjustable design, so you gain 2x the amount of adjustment and you don’t need to rely on your cam bolts to make toe adjustments. As well, our design utilizes teflon-lined spherical joints, so there will be zero deflection with these arms. The balljoints are greasable for quick servicing. The extruded main body is incredibly strong due to it’s shape, but also very lightweight due to the 6061 material. We recommend installing these to the subframe with OE hardware to keep attachment aligned and secure, but you will no longer need to use those cam bolts for adjustment.
