McLaren P1 RaceActive Chassis Control (RCC) McLaren P1 features adjustable ride height as part of the new hydro-pneumatic suspension. Image: McLaren Automotive Static ride height at the front and rear of the vehicle may be independently adjusted by pumping hydraulic fluid from heave bump hydraulic circuit 33 to heave rebound hydraulic circuit 31 and vice-versa. For both the heave and roll circuits, stiffness may be adjusted by pumping hydraulic fluid equally into the respective hydraulic circuits to compress gas or air in the accumulators to adjust their spring rate.

In the final step, the motor transmits the optimum servo torque – via worm gear or recirculating ball gear – to the steering rack (EPSapa) in the mechanical rack and pinion steering system. The method of making a wheel as set forth in claim 5 wherein said weld joint is made by arc welding a flare bevel full-penetration weld with the outer surface of said weld being generally flush with the adjacent surface of said rim outboard bead seat surface.
