I'm always interested in offline tips for racing AI please, although I usually give myself 10-20kgs and 10% restrictor just using CM
Well, for the layout i use in the vid, it's basically tweak and try.
using Cartuner available here :

You pick a bunch of cars you wanna race against on a specific track. Let's call them A, B, C. Watch your pace, and watch theirs.
You do a lap in 1 minute. That's the pace you're aiming the AI to run at.
AI Car A runs a lap in 1.06 seconds. Open car A in Cartuner. Create a new tune named, ie, "BOP 10", then apply a 10% boost in the "torque" and click apply.
AI Car B runs a lap in 1.03 seconds, same operation, but you want it to actually beat you because IRL it should be 1 or 2 seconds faster than you are. Enter a 7% torque and click apply.
Now when making a quick drive grid, there's now a CAR A and a CAR A BOP 10, a CAR B and a CAR B BOP 7 available. It creates a copycat folder for each of them, so getting rid of the failed ones is easy.
Run the race with your new overpowered AIs, see their pace, adjust the torque depending on their results until they are 1 second faster than you.
Now with Cartuner there's a lot more to play with in the advanced settings, but so far the only thing i dared tweaking were the tyre models. You can, for example, switch a 60s tyre model for a vintage one, getting whole new grip in the process. For AI cars that struggles with drifting, that could fix a lot of issues. To my knowledge so far each time i tried to modify the car files (apart from the tyre model copy/paste from other mods) i ended up with either a struggling AI or a setup glitch. The Torque adjust seems to run fine everytime.
I wouldn't touch the drivetrain nor the engine settings to maintain mods the way their creator intended them. But for AIs? Who cares, you just want to sweat blood overtaking them.
Now as i was testing everything, i aimed for my pace. But now i would go for a 5% faster AI whatever the conditions : You now have the ability to lower the AI opponents strenght directly in the quick drive menu, instead of keeping it at 100% and pray for more than a lap battle. You can also balance some same era cars from different modders that have completely different pace and get something coherent, with a complete 20 cars grid running without gaps.
It's pretty easy, a little boring, but very satisfying. Save the grid preset in CM, and you don't have to think about it for your little championships accross different tracks.
I just tried my settings on Oulton Park 60s with the layout i created for the vid and i can't for the hell of it go past 14th place. It's amazing, i never struggled that hard against the AI...
