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.

Tip: Don’t stack adjustments. Make one adjustment at a time and test it.

  • Bold face remedies are the go-to fixes for each symptom. You might try those remedies first.
  • This matrix is based on the components in the iRacing Advanced Legends Ford ’34 Coupe. These settings apply to any asphalt oval cars although there are fewer settings on the Legends car.
  • If you are going to make any spring or cross weight adjustments, please see this page first.
