With the old iRacing forums going offline at the end of this season, I recalled a thread with some absolute jems of information on setting up the top 3 iRacing Oval cars. Was kind enough to allow me to post it.
SETUP TIPS Setup Tips by Dale Jr Heres some interesting real world info vs iracing. Car: Cot Track: Charlotte Real world right side air pressure baseline Race: RF 60 RR 58 Qual: RF 75 RR 70 What many used in the WDC Charlotte race last week Race: RF 56 RR 56 Qual: RF 61 RR 58 Blowing up your right side tires to go fast is common knowledge in the real world.
It appears that in this one case the real world pressures are even higher than what many used in one of the top series in Iracing. I would expect that higher air pressure would be quicker, but I would be surprised if someone is running these types of pressures online for the entire duration of an event. Left side air at Charlotte this week is about 2-4 pounds higher than in Iracing in race trim. ——————————————————————————————————————————— I would be surprised if anyone can make a setup in iRacing at Charlotte for example with over 65 pounds in the right sides that would be real competitive over a full fuel run. My method to getting the cambers and tire temps is this. It’s quite simple. Get a baseline on the front springs.
Get a baseline on the chassis heights. Go run some laps. Stop, look at temps, adjust cambers to even out the inside and outside temps. Also adjust air pressure to bring the center temp to within a few pounds of the outer temps. Reset heights throughout this process. Go run some laps and repeat this process. After a 10 lap run I want to see all the temps on the right front tire to be as close as possible.
The left front tire will most likely perform the best with a little more camber which will produce more temp on the outside edge of the tire. Any where from -5 to -7 degrees. Air pressures in the left are different for each track, I just run laps and find a setting that gives me the best grip for the exit. I don’t run the trucks enough to know. But in the NW and COTI run the nose as low as you can.
I run the springs as soft as you can. My front heights are consistent in these two cars from track to track. The front springs are always very soft, usually in the 350 to 600 pound range. On smoother tracks I can run softer, but on a track with bumps like Vegas I may need a bit more spring. ————————————————————————————————————————– From my experience I choose the LR spring by how the car gets forward bite on exit.
Do any of you guys have the VHR 2013 NASCAR mod for. I like VHR a lot more than iRacing. Unfortunately adding a stock car division here at CMS is not. Vhr Stock Car Setups: Software Free Download. Download karizma classic setup. The Cup Nextel Stock Car 2009 was the 31th. Iracing Oval Series. Iracing Setups Discussion. VHR Stockcar.
I choose the RR spring that helps the car rotate in the center without making it over rotate. Also adding RR spring will sometimes make the car aero tight on entrance at a track like Michigan so when I get that feeling I can either back off the RR spring or take out some nose weight.
We are able to run about the same springs in the NW car here and IRL. In the COT we are able to run a little softer than what is currently common IRL. That doesn’t mean its wrong or unrealistic. What we lack in the COT on Iracing is the ability to adjust the bump stop compliance and the bump stop gap. So I would assume that with those two settings currently in their fixed state on iRacing in the COT, we are limited in our ability to be more creative with our choices in optimal front spring settings.
I’m sure one day we will be able to adjust the bump stop gap and the compliance. That will open up the range of springs you would put in the front and the choices there would be closer to IRL.
——————————————————————————————————————————– Something that I have learned about the garage over the last several builds. I will credit Chris Shearburn for pointing this out to me.
Looking at the COT garage you’ll see two pieces of information: Shock deflection Spring deflection To my knowledge, this is what this information is telling you. If your looking at your right front and your shock deflection is 3.45″ of 5.75″ That means you have 2.30″ inches of travel before you will engage the bumpstop. You do the same math with your spring deflection.
