Better design better consistency
The Neuline Lift Arm is the most efficient way to translate axle wrap torque into downforce. By reverse mounting to pull from the bottom of the chassis, we increase tire loading and rear bite consistency. As the rear end drives forward under throttle, our slider design allows the lift arm to travel forward without affecting the bushing stack angle. This helps keep rear bite constant lap after lap.
With traditional lift arm designs, the 5th coil acts as an individual link between the lift arm and the chassis. Just like a pull bar the angle of the link determines how much downward force is being applied to the rear tires. Any rear end movement will also change the 5th coil angle which will change the rear bite, producing a very inconsistent chassis.
Pull bars connect to one point on the rear end above the axles and resist axle wrap torque by pulling horizontally on the chassis. Pull bars rely on its angle to adjust rear bite in the car. Any chassis movement will also change pull bar angle and change rear bite producing an inconsistent chassis.
