Dear staff, can you please fix your tire physics and become first sim in the world that use real data for tire physics. As a real KZ-2 driver i can say that your all tire physics and grip is worked in opposite way than in real life. I don't know where you find this technical data, but your info is wrong. Last two moth i burn 10 sets of real slicks, i know what i'm telling. But of course there must be some corrections 1. Tire pressure can give tires more heat. If we have cold weather, we must inflate tires more for faster tire temps build up. I drove 10 laps in F4 in 30 degrees and my tires was only 45C. It's a joke. Even young real driver know, low pressure is not a solution for tire heat and grip. Of course it depends on track temperature but overall that's true 2. Softer car don't give you more grip if you softer suspension to infinite. 3. Stiffer can can give more heat and more grip with limit at some point and then there is too stiff car and sliding too 4. There is only one window of car stiffness, where the car have ideal grip and this stiffness depends on grip of the track. Just made your tire physics opposite way lol. Low track temp - more inflate. High track temp - less inflate. Too soft suspension - less grip because not enough tire load. Too stiff suspension - less grip because of overloading the tires. If you just fix this amateur errors in your tire core physics, you will become more friendly sim for real drivers. I can't to know all secrets, but this is a base of knowledge. USE IT PLEASE!
