This is an optional XRAY Adjustable Rear Anti-Roll Bar Set, and is intended for use with the XRAY RX8. Perfect for serious racers looking for the ultimate in anti-roll bar tunability, this rear anti-roll bar set allows you to quickly and easily adjust rear stiffness without replacing any parts and creates a noticeable difference in handling. Features include a beautifully CNC-machined roll bar body made from premium Swiss 7075 T6 and anti-roll bar blades machined and precision hand ground from world's most exclusive Hudy Spring Steel that have been specially hardened to provide extra long life and high strength. The set has two adjustable anti-roll bar blades that are locked in place by easily-accessible set screws. The anti-roll bar is mounted to the rear bulkheads in precise ball bearings that ensure smooth action.
After long term testing the XRAY R&D team has developed an anti-roll bar system with optimal flex, allowing extra flex while still being stiff enough to transfer the anti-roll bar function through the blades.
