iRacing – Oval Setup Tunning

Here we have a nice and always evolving resource to understand and manage oval setup adjustments:

The “ULTIMATE” Racing Car Chassis Setup Guide and Tutorial

This is a very complete guide about NASCAR and other oval disciplines. Rodney Arndt wrote this guide, and keeps doing it, helping newcomers and beginners. He is a former NASCAR race car driver and also has helped Papyrus (later iRacing.com) to develop and implement what real drivers think a car should do in racetrack.

Guide covers many different subjects as aerodynamics, shocks, gears, pressures, front and rear adjustments and bars. In this guide you will also find some cheatsheet downloads to help when you’re in testing.

A very small extract from the whole document:

“As a general rule, the smaller the track & tighter the turns, the more toe out you may need. Larger radius tracks with long corners would require less toe out. More toe out will help the front end stick entering a corner. Running too much toe out will scrub off speed down the straightaway & create an Under steer condition. A car will run faster with the toe straight. By monitoring tire temperatures you can tell if you have a toe problem with the chassis. Excessive toe out would show higher temperatures on the insides of both front tires. Excessive toe in would show higher temperatures in the outsides of both front tires. Front toe in or out will cause the same feelings to a chassis as excessive amounts of camber & caster, albeit to a much lesser degree. Front toe out isn’t an adjustment that has to be changed or monitored as often as camber. Start with an adjustment of 0.050 & you will be close. Adjust the toe slightly only when the rest of the chassis is real close to being correct.”

  1. I would like to read this guide but the web site it is published on is horrible. The web site is very distracting to the text. Is there any way a PDF of the text could be published?
