Hi Kenwilinski,
I was todl my xxDesperado that you are the man i need to speak to about tunign my nascar.
Basically i have a race coming up on 1ndy R0ad Course and its a 40 laps race. I know there are a few tunes for nascars for oval tracks but obviously these wont work for the Road course.
Do you have a setup for this course please? (or anyone else have a setup?)
Please bare in mind that im not an avid tuner so please be gentle lol
P.S Its on Racing Hard tyres by the way
Cheers
Here's a post I have in this thread for a NASCAR Road Tune that I use. It follows a link to my friend's tuning garage, I borrowed his after coming up about a second short on my own tune.

Things I would change to fit your exact race are:
1.) Adjust Transmission to 217mph (this will leave room to slingshot on the straightaway)
2.) Turn the LSD Initial Torque down 15 pts or more & the Accelerator Sensitivity up 15 pts or more. (this will help not over spinning a hard tire)
3.) Increase spring rates 1.5pts each (this will help on tire wear & traction for hard tires)
4.) If you feel understeer, minimize the aerodynamics
5.) If you feel oversteer, add more aerodynamics or add one roll bar to the rear end.
6.) If you still feel understeer upon corner entry, add more negative toe angle to front wheels
7.) If you still feel understeer from apex on out of turn then add more negative to rear wheels
8.) Any more unexplainable understeer then add a little more camber like .25 to the front first, then the rear. And if you still have to, drop the car height down more.
9.) Any unexplainable oversteer such as snap oversteer, which will most likely happen if you took the tune this far. I would try lowering the LSD a little bit.
But if really know this course and the driving lines, just remember slow-in and fast out. And maintaining throttle control in the corners so you don't have to turn down your LSD. You need the LSD hi up in a NASCAR. And lowering the LSD in a NASCAR will result in needing to drop the transmission to peek the hi rpm since you will not be deliberately sending hi torque through the differential via LSD.
I would definitely recommend taking steps 1, 2 & 3. And if needed 4 or 5. Indy is a very smooth and flat track, so driving line is what will really make your car turn here.
