Xray XB4 graphite arm stiffeners
Made for both the XB4 4WD and 2WD buggies are these graphite arms stiffeners from Xray. Made from 1.6mm carbon fibre and coming as front and rear set, the plates directly screw to Xray’s SFA arms in order to adjust the overall flexibility of the composite material lower A-arms. Using the stiffeners can help with vehicle handling especially in medium to high bite conditions and also at high ambient temperatures as a stiffer arm makes for a smoother steering response and better car control especially in chicanes and in tight corners.
