iRacing Dirt Late Model Setup Matrix

• Decrease RR Tire Pressure (Tightens car throughout turn.)
• Decrease LF Spring Rate*
• Increase RF Spring Rate*
• Increase Left Trailing Arm (Will loosen car on exit.)
• Decrease Right Trailing Arm (Will loosen car on exit.)
• Increase Chassis J-Bar Height
• Decrease Axle J-Bar Height
  (More J-Bar rake (split) produces more traction and more body roll. Remember, traction creates roll, but roll does not create traction.)
  
  
• Increase Cross Weight / Left Rear Bite (May loosen car in middle and on exit.)
  (The proper method is to increase LF and RR spring perch offset and decrease RF and LR spring perch offset.)

• Increase Axle Lead (Tightens car throughout turn and may destabilize/slow car on straights.)

• Decrease RR Tire Pressure (Tightens car significantly throughout turn.)
• Decrease Rear Stagger
• Decrease RR Spring Rate*
• Increase LR Spring Rate*
• Increase Chassis J-Bar Height
• Decrease Axle J-Bar Height
  (More J-Bar rake (split) produces more traction and more body roll. Remember, traction creates roll, but roll does not create traction.)

• Decrease Ballast Forward (Increase Rear Weight)
• Increase Cross Weight / Left Rear Bite
  (The proper method is to increase LF and RR spring perch offset and decrease RF and LR spring perch offset.)

• Increase Axle Lead (Tightens car throughout turn and higher/lower extremes may destabilize/slow car on longer straights.)

Logitech G920 Driving Force Racing Wheel & Pedals

This serves as a no-nonsense entry into realistic driving. Dual-motor force feedback delivers honest steering weight and road detail, while the sturdy floor pedals offer progressive braking and smooth throttle. Stainless steel paddle shifters, a leather-wrapped rim, and a full 900-degree rotation create a setup that earns its spot on your rig without needless extras. It works cleanly with Xbox Series X|S, Xbox One, and PC.
