edit up front: I did a google search on 'I' racing and dirt. I found those at 'I' racing don't do dirt because it's too tuff for them to do. Not knowing about 'I' racing I wrote what is below not knowing LTO dirt was not included 'I' racing. I think what I wrote is good and it might apply to 'I' paved oval racing, so I'm not deleting it and leaving it here hoping the last two questions I asked might generate discussion. I think the over all jist of what I wrote about 'I' racing and racing not relating exactly to each other might be a valid point for why 'I' racing setup does not transfer to racing.
edit just behind up front ...
I found this I racing setup guide, seems like a good read:

What makes a car fast 'I' racing?
What makes a car fast racing?
Are discussions to put a good baseline setup on the track and fix on track problems to go fast with a real car, based on the same reality as 'I' racing?
The reality of racing is how what your racing needs to be used to go fast, weather it's 'I' racing or racing. Setup for racing is done by matching how what your racing is used with available grip and the hp you have available. It's done to make what your racing able to operate in the most efficient way.
When you input your setup 'I' racing what is it you have to match up with, in order to be fast?
When racing you have to match up using your available hp with available grip, at every place around the track efficiently. There are three basic types of race cars. Those with a differential rear end and all the combinations of a limited slip differential, those with a solid axle or no differential, and those with a solid axle and stagger. Each of the three types will be used differently braking, turning and accelerating. Racing and knowing how to race remain the same between the three. Setting up each of the three will be different, because each of the three use tires differently around the track.
Unless those who program 'I' racing understand how each of the three different types of cars need to be used and have programmed to match each type of car to reality, there becomes a fourth type of reality and car. When you setup to 'I' race your setting up to match with the made up racing reality of a programmer. The physics written into the program if correct will be the same as reality for each of the three types of cars. But I doubt how a car in a made up programmed reality needs to be used to be fast, will transfer to how real cars need to be used.
I have an 'I' racing question.
When you have an on track problem 'I' racing, do you fix the problem by changing how your tires interact with the track based on how they need to be used, or do you make adjustments you think or know from playing experience will fix the problem?
And then the same question racing.
When you have an on track problem racing, do you fix the problem by changing how your tires interact with the track based on how they need to be used, or do you make adjustments you think or know from racing experience will fix the problem?
