Now updated with information from New Tire Model (NTM)
I still use the Setup Tweak Guide a bunch.
The default iRacing Indycar oval setups carry a lot of wing and are quite stable to drive. The problem is they’re also a lot slower than folks are generally running in the series.
Over the last few seasons there have been some great setups posted in the forums, while some were very very fast, I found a lot of them to feel funky, twitchy or downright dangerous.
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.
