Hello!
Are you using Content Manager? Obviously through there you can use restrictors and ballast to slow certain cars down. That's the easiest non-obtrusive way to do it. The only issue with that is you're constantly slowing down faster cars to the weakest link.
The next way to get you into the ballpark is to use content manager to calculate the power to weight ratio. Right click on the 3 dots next to the power band display on the cars page, select the third option, calculate power using the data. (Sorry, not on rig computer, doing this from memory) Next right click over the weight of the car and recalculate. Do this for all the cars in question and see what the data tells you. You're aiming to get the power to weight ratio fairly close. There can be a lot more to it but this is a great start and you'll be able to use this on different groups of cars.
Next would be to go into the data folder and change values. This is obtrusive to the cars so you would want to create a back up of the data folder or data.acd file depending on which is in your folder. Most likely with the cars you listed the data will be packed and you'll have to unpack the data via content manager.
If you feel comfortable with that, we can go from there.
Excellent. I will try this and see how it goes. The weird thing is, i have just donw 3 test runs (to see if 1 car is an outlier) but in all 3 races, different cars won each race with different cars in the following places (1st 2nd 3rd).
But in each race, the winners were around 30s faster than the 5/6/7/8/9/10th place cars. But in race 1 corvette and BMW were 30s faster, in race 2 911 was 30 seconds faster, in race 3 AMG was 30s faster??
So it seems its not related to a specific car?
I was testing at the new Bsathurs reboot track? Could it be realted to the AI on that track? Could it be the NEW AI setting in CM?
It just seems that no matter what, with that combination of cars, 3 will be 30s faster than the rest of the field, and its any random 3 cars that seem to be picked to be faster?
