I came across Boomer Studios Racing and he noticed that the oval tools such as the weight jacker and the bars do not seem to have an effect on the car on ovals. Are the oval physics not working properly? This would be a huge gaping hole in this content, as the oval tools working properly would be a huge indicator that the physics are simulating oval racing properly.
Weight jacker is working appropriately, you can even see it visually: It also affects car balance. A tight baseline setup doesn't mean that tools aren't working...
I replied to boomer's video if anyone is interested. I figure automatically dropping all front aero off the cars at fontana is an iracing thing, but its problematic.
