The default iRacing oval setups tend to be reasonable with a little too much push (understeer) for my taste, especially the fixed setups. This is so that most drivers can get in and get around the track without wrecking at every turn and causing a wreckfest.
Over the last few seasons there have been some great setups posted in the forums, some can be a little on the sketchy side. I like to have a comfortable truck that will stay under me for the long run.
This guide is an attempt to outline how to adjust the car and what makes a fast setup. This is a community effort and I’ll post updates as folks chime in.
I still use the Busta Wrench Setup Tweak Guide a bunch, especially for the oval cars.
