Sim Racing Setup

Tyres

  • Go as soft as you can for quali without overheating. If you're getting uneven tyre pressures, add tyre pressure to the tyre that is cooking.

Alignment

Toe

  • Toe out on front gives more responsive turn-in, can cause oversteer
  • Toe in on front does opposite, can be used on rear to increase stability

Camber

  • If you have uneven tyre temperatures, it's worth adjusting camber
  • If inside is too hot, add positive camber
  • If outside is too hot, add negative camber

Anti-roll bars

  • Increase front stiffness to induce understeer during turn in, soften to increase oversteer
  • If you are oversteering on turn out, soften the rear, if you are understeering, stiffen the rear

Springs

  • As a start, lower the spring rate on all four springs to see if it negatively impacts handling
  • If the car starts to bottom out, you've gone too far
  • Balance wise, softer springs at the front will give more oversteer, whereas stiffer springs more understeer
  • Rear springs are opposite, softer gives more understeer, stiffer gives more oversteer
  • Use this if ARB isn't doing what you want

Dampers

  • If the car is bouncing too much, increase damper values
  • If the car is too stiff under movement, decrease damper values
  • Slow refers to natural movement of car (cornering, braking, acceleration)
  • Fast refers to impacts - think kerbs, bumps etc
  • If your car feels twitchy or unpredictable during weight transfer, consider reducing damper values

Ride height & rake

  • You want to be as low as possible
  • Changes to ride height will often be reactionary to other changes

Brake bias

  • Moving towards the front makes it more stable under braking, but can induce understeer during turn in
  • Towards the front is the exact opposite

Diff

  • Diff allows each pair of wheels to rotate independently of each other
  • Power setting affects how locked/open the diff is under power
  • Coast affects when you're not on the power
  • The higher the number, the more locked
  • Preload is the minimum amount of lock
  • Car with locked coast diff will understeer on turn in
  • Car with locked power diff will oversteer when applying power

Aero

  • Wing: increase angle, more downforce, but more drag
