Xray is proud to announce the release of their new graphite lower arm plates for the XB9. These optional upgrade parts allow for stiffer arms and make the car more stable and easier to drive under high-grip conditions. The plates can be easily mounted / dismounted on the arms with 4 screws, and easily change the hardness of the whole front suspension.
