With more weight supported by the rear suspension, we would imagine the spring stiffness would be greater at the rear. We're one of racing's best kept secrets. As the car dives and rolls in the turns, the steering connecting rod pushes or pulls on the steering arm at the spindle causing the wheels to steer when there is no steering input by the driver. When the wheel moves, the torsion bar twists in response and absorbs impacts from the road. For example, spring or torsion bar rates, crossweight, chassis tilt, wheel tracking/spacing, wing position and angle, can all be used. Strange Oval torsion bars have been winning races since 2008. 10. 327 cubic inch Maxim Tech Setup and Misc.
