Based on excessive knowledge gained from the previous XB8 cars, several different suspension arm designs were tested in both virtual reality and in-car to find the final best design. The exclusive composite mixture used for suspension arms is a perfect balance between reliability and performance. The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough to survive extra-long main events.
The arm features two different rear anti-roll bar positions. The smart design allows the same rear arm to be used on both left and right sides.
