FRONT CORNERS

C ORNER W EI GH T
The weight under each tire while the car is stationary in the garage. Weight placement around the car is crucial to a car's
performance and is ultimately what determines how the car handles. These are not directly adjustable, but will change frequently
through the setup process due to changing loads on the suspension. The most effective way to change the values is through the
Torsion Bar Turns setting, however all four corner weights will be affected.
RIDE HEI GH T
Front Ride Height is the distance from the ground to the bottom of the chassis plank projected to the front axle. These are
reference heights, not necessarily ground clearance values, so values of zero (or even negative) in telemetry may not necessarily
indicate the chassis being in contact with the ground.
T ORSIO N BAR DEFLEC T ION
Torsion Bar Deflection is how far the suspension torsion bars have deflected from their unloaded state. Higher deflection
equates to more preload on a given torsion bar, while lower deflections indicate a bar with less preload.
T ORSIO N BAR T URNS
Each torsion bar can be preloaded to raise or lower a given corner of the car and increase or decrease the preload on the torsion
bar springs. Increasing the Turn value will preload the torsion bar and raise the corner's ride height, decreasing the Turn value will
reduce the preload on a given torsion bar and lower the corner's ride height.
T ORSIO N BAR O. D.
The corner Torsion Bars are the spring elements for each corner of the car and behave in the same way as a conventional
coil spring. The Outer Diameter of each torsion bar determines the bar's spring rate and how stiff the bar is through changing
suspension loads. Larger diameter bars will have a higher spring rate and will be stiffer, which is great for maintaining a consistent
aerodynamic attitude around the track but will reduce mechanical grip, especially in slow corners. Smaller torsion bars will have
a lower spring rate and produce more mechanical grip, however the extra movement from the suspension can hurt aerodynamic
performance at high speeds.
