FRONT CORNERS
CORNER WEIGHT
The weight underneath each tire under static conditions in the garage. Correct weight arrangement around the car is crucial for
optimizing a car for a given track and conditions. Individual wheel weight adjustments and crossweight adjustments are made via
the spring perch offset adjustments at each corner.
FRONT RIDE HEIGHT
Distance from ground to a reference point on the chassis. Since these values are measured to a specific reference point on the
car, these values may not necessarily reflect the vehicle’s ground clearance, but instead provide a reliable value for the height of
the car off of the race track at static values. Adjusting Ride Heights is key for optimum performance, as they can directly influence
the vehicle’s aerodynamic performance as well as mechanical grip. Increasing front ride height will decrease front downforce
as well as decrease overall downforce, but will allow for more weight transfer across the front axle when cornering. Conversely,
reducing ride height will increase front and overall downforce, but reduce the weight transfer across the front axle. Minimum legal
front ride height is 50.0 mm.
SPRING PERCH OFFSET
Used to adjust the ride height at this corner of the car by changing the installed position of the spring. Increasing the spring perch
offset will result in lowering this corner of the car while reducing the spring perch offset will raise this corner of the car. These
changes should be kept symmetrical across the axle (left to right) to ensure the same corner ride heights and no change in cross
weight. The spring perch offsets can also be used in diagonal pairs (LF to RR and RF to LR) to change the static cross weight in
the car.
SPRING SELECTED/SPRING RATE
This setting determines the installed corner spring stiffness. Stiffer springs will result in a smaller variance in ride height between
high and low load cases and will produce superior aerodynamic performance through improved platform control however, they
will also result in increased tire load variation which will manifest as a loss in mechanical grip. Typically the drawbacks of stiffer
springs will become more pronounced on rougher tracks and softer springs in these situations will result in increased overall
performance. Corner spring changes will influence both roll and pitch control of the platform and ARB changes should be
considered when altering corner spring stiffnesses in order to retain the same front to rear roll stiffness and overall balance.
When reducing corner spring stiffness the ARB stiffness (either via blade or diameter depending on the size of the corner spring
change) should be increased to retain the same roll stiffness as previously. 6 options for spring rate are available ranging from
