I have been doing some testing and I finally came up with a race setup which I can run a full tank without hitting the walls. I will post it here, you can share it if you like. Edit Monday, May 18th. I have modified my setup, the latest one is now here and the last post. I changed the setup slightly and it really helped the handling at the end of the run. It also helps with the tightness at the start of the run. If you hit the corners just right, you can keep it floored for the entire run and run consistent 40.5s and 40.6s with a few 40.4s on near perfect laps. All I did was move the ballast more forward. Check notes for the changed WJ and ARB suggestions. 2015 Indy 500 R V5.sto (3.35 KB) In the IndyCar, you need to make adjustments while driving as you go through a fuel run. There are 3 things you can adjust which will affect the handling of the car: Weight Jacker (WJ), Front ARB, and rear ARB. You can also adjust Brake Bias and Fuel Map, but these 2 don't affect the handling on an oval. You can see the ARBs, Fuel map and Weight Jacker settings while driving. The ARBs are the 2 numbers just to the left of center on the steering wheel display. The left number is Front ARB and the right number is Rear ARB. The range of the ARBs is 1 to 6. The number just to the right of center is the Fuel Map number. The range of the fuel map number is 1 to 8. The 2 numbers to the far right is the Weight Jacker setting. The range of the WJ is -20 to +20. When creating a setup, you can only save it with the Weight Jacker at 0. If you need to have a WJ setting other than 0 to start, you must set it after you get in the car. If you get out of the car with a WJ set at anything other than 0 and go into the garage, the setup will fail until you set it back to 0. You can change setting while driving one of 2 ways. Either go to the F8 screen (in car adjustment black box) and change them there. Or do what I do and have buttons assigned to them on your wheel/button box. I personally use the right joystick on my Fanatec Clubsport BMW wheel for the Weight Jacker, and I have rotary knobs on my button box for the ARBs, Fuel Map, and Brake Bias. Check the notes in the setup for adjustments needed during the run. I base my adjustments on how I feel the car is reacting, but I have put some fuel milestones in there for those less experienced in the IndyCar. Where you see the note at 10 gallons, it means when you have about 10 gallons left in the tank. There is a digital fuel gauge on the steering wheel. It is to the right of the Fuel Map number. For the WJ numbers in the notes they mean T1, T2, T3, T4. You always need a little more WJ in T1 and need to back it off for T2 and then leave it until you get back on the front straight for T1 again. For the ARB numbers in the notes, they mean Front ARB/Rear ARB. If you want to adjust the setting by feel, here is how they work: Weight Jacker (WJ): Increasing the WJ (making it more positive will make the car looser). Decreasing the WJ (making it more negative will make the car tighter). So if you are too tight in the corners, increase WJ, and if you are too loose in the corners, decrease WJ. Front ARB: A higher number will make the car tighter, a lower number will make the car looser. Rear ARB: A higher number will make the car looser, a lower number will make the car tighter. If any of this is too confusing, don't be afraid to ask questions. I know it is a lot to think about during the race, but it is the only way to have a decently fast setup. Edit: Another thing to remember. These cars have a lot of draft and a big aero push when following another car. So you need to adjust your WJ depending on whether you are behind someone or in clean air. You will also need to lift into the corners when following close behind someone or you will head straight to the wall on exit. You must lift before the corner, if you try to lift during the corner, it is already too late.

2015 Indy 500 R V4 george.sto (3.47 KB) Here Troy, I took and made some changes to your set. It was a bit tight in turn 1. The best I could do with it was a 40.87, and this one is a 40.460. Lowered the rear wing angle 0.3 degrees. Changed front ARB to small. Changed rear ARB to large. Sealed off radiator inlet to 1/3. Wear seems okay, but the RR is getting a bit warm. Run a stint with it and tell me how it is?

George, it's a great setup if the race would only last 15 laps. After that it just gets too squirelly no matter how I adjusted the WJ or ARBs. If it works for you, that's great, then you should use it. I know my setup is tight at first, but that can be tuned out with the WJ in car. The trick is to find a balance of speed and handling that will last an entire fuel run. I'm sure there are plenty of faster setups out there than mine, but nobody is sharing their race setups. Mine is completely made by me from the fixed setup. I can run it flat out for at least 20 laps, then I only need to lift in T1 or when behind other cars. If you make any changes which make the car more stable on the last 10 laps of a fuel run, let me know. I will continue practicing with mine for now. Edit: New version of my race setup. I also edited my earlier post. I changed the setup slightly and it really helped the handling at the end of the run. It also helps with the tightness at the start of the run. If you hit the corners just right, you can keep it floored for the entire run and run consistent 40.5s and 40.6s with a few 40.4s on near perfect laps. All I did was move the ballast more forward.

Going to test these out later tonight too. Should be dialed in enough to keep it off the wall!

Just a reminder for anyone planning to run the Indy 500. If you plan to qualify, you must do it by Thursday at 23:59 GMT. There will be no qualifying sessions available on Friday, Saturday, or Sunday.
The last qualifying session will be on Thursday at 23:30 GMT / 7:30 PM EDT / 4:30 PM PDT. Get your qualifying run in before then.

2015 Indy 500 R V4 george.sto (3.47 KB) Okay, this is the best I can do. Doesn't feel loose or tight, and takes the fuel burn well. I didn't need to adjust anything in-car while I ran a fuel run either.

I made it 43 laps (a new personal best!). There was an incident in pit lane where a car coming out of his box jumped a car coming down pit lane. I rear ended the car coming down pit lane, which caused some front aero damage. On the next green flag lap I lost control in T4 due to the damage and nearly regained control before a car from behind me came low and tagged me.
How is everybody else doing???

^ Watched that whole race. One bonehead who led 120 laps decided to pull a lap 200 pass with 50 to go on third place to get back what was his. Did it clean, washed up in front of the guy, and the guy couldn't check up in time. Rear-ended the hero, took out several top-10 cars.
After that, it was pretty much Nigel and Josh's race.

Here is my race for those who are interested. I opted to stream my race tonight instead of recording it, so sorry for the bad quality. I haven't streamed in a while so it's clear that my settings aren't up to snuff.
WARNING SOME PROFANITY!

Tony, your race lasted a couple of laps longer than mine. I took myself and another driver out on lap 39. I take about 80% blame for the incident. I was clearly faster than the other guy and coming up on him really fast going into T1. I got the inside line just before entry, but his spotter didn't announce it until too late. He said he heard "car inside" just as we came together. I held my line low, but he wasn't expecting me to be there. I take responsibility because it was a bit too aggressive for so early in the race.
I will try again tonight and if necessary, tomorrow morning.
