Sim Racing Car Setup Explained
Explains what will happen if you change setup values.
Tyres
Front Tyres
More pressure brings more precision and less roll friction, but more deformation and heat generation.
More negative front toe increases precision, natural may be less precise, but less longitudinal friction is generated at high speed. Positive will increase agility in slow corners.
More negative camber can help lateral grip, but generates a smaller friction surface and more local temperature gain and local tyre wear. Less helps traction and braking.
More caster helps self re-alignment of the steering wheel, while less will require you to drive.
Rear Tyres
More pressure brings more precision and less roll friction, but more deformation and heat generation.
More natural (0 or positive) toe will increase turn-in stability, while negative values will make the car rotate more during turn-in to make the car more ogille in that phase.
More negative camber can help lateral grip, but generates a smaller friction surface and more local temperature gain and local tyre wear. Less helps traction and breaking.
Electronics
Electronics
Set Traction Control, limiting or preventing excessive slip of powered wheels. Higher values for more intervention and slip limitation.
Set Traction Control 2, complements TC1 by finetuning the aggressiveness of the power cut when slip threshold is reached.
Anti-lock braking system is a braking related electronic control allowing the vehicle to avoid wheel-lock under braking. Higher value for more intervention, lower for less intervention.
Set the number of laps which telemetry data is to be recorded in the current session.
Suspension
Front Suspension
Higher means stiffer, which equals less roll.
Softer can provide oversteer, stiffer can provide understeer.
Brake Bias adjustment allows you to move braking power in the front (higher value) or towards the rear brakes (lower value).
More front BB can cause understeer, more rear can cause oversteer under braking.
Steer ratio is the ratio of how much the steering wheel turns to how much the front wheel turn, determining steering responsiveness.
Lower values (softer) improve grip and compliance over curbs whereas higher values (stiffer) improve responsiveness and reduce body roll. Making the front stiffer shifts the overall balance towards understeer and more aerodynamic stability under braking,
Set the rate of the bumpstop to manipulate values and behaviors when the damper reaches the bumpstop limit. Stiffer bumpstop may make it more responsive and precise, but also more aggressive in handling.
Set the limit of the travel of the damper to its bumpstop. Less travel can cause premature bumpstop and aggressive reaction on the handling of that axis, but too much travel make the car less precise.
Rear Suspension
Lower values (softer) improve grip and compliance over curbs whereas higher values (stiffer) improve responsiveness and reduce body roll. Making the rear stiffer shifts the overall balance towards oversteer in all scenarios.
Set the rate of the bumpstop to manipulate values and behaviors when the damper reaches the bumpstop limit. Stiffer bumpstop may make it more responsive and precise, but also more aggressive in handling.
Set the limit of the travel of the damper to its bumpstop. Less travel can cause premature bumpstop and aggressive reaction on the handling of that axis, but too much travel make the car less precise.
Higher means stiffer, which equals less roll. Softer can provide understeer, stiffer can provide oversteer.
Higher Preload of the Differential requires more toque difference between the rear tires before they spin more independently. During deceleration more preload helps stability, during acceleration, but more snappy.
Dampers
Front Dampers
Adjust the damping value on compressing weight transfer. Dampers control the speed of weight transfer.
Lower (softer) front values generate more ease for the front to lower under braking.
Adjust the damping value on extending weight transfers. Higher (stiffer) front values generate less ease for the front to extend under acceleration.
Rear Dampers
Adjust the damping value on extending weight transfer. Dampers control the speed of weight transfer. Lower (softer) rear values generate more ease for the rear to compress under acceleration.
Adjust the damping value on extending weight transfers. Higher (stiffer) rear values generate less ease for the rear to extend under braking.
AERO
Front Aero
A higher front will generally shift the balance towards understeer and will reduce total downforce on race cars with advanced floor design.
Rear Aero
A higher rear will generally shift the balance towards oversteer and will increase total downforce on race cars with advanced floor design,
Higher values for more rear downforce, witch typically generates more grip, stability but slightly more drag. Lower values will allow drag reduction and typically reduce downforce and stability.
