Interesting thing about oscillations when doing burnouts that are seen in those telemetry outputs. I wonder what it is. Could be the way they generate grip doing wheelspin. Tires might have this pattern of slip-grip-slip-grip, and it could transfer oscillation into chassis I guess... Well maybe, it would probably be stronger with drivetrain wobble if it was there in rF2 (although car like that probably wouldn't have that happening). I think it is same as this wrinkle effect as seen in this dragster clip, just of course on dragster it is way bigger: I also suggest that it is not that hopping somehow gives car better traction. It is other way around better traction gives car hopping. Each of that wrinkle is a sign that tire is gripped and locked to the surface, then it slips through while transferring torque to the car to make it move forward, meanwhile it grips again in same way. It is actually happening all the time in driven wheels when car is being propelled forward by them, it just happens very fast and with a lot more tiny slips, and as slip ratio grows slipping area of contact patch grows, till it is 100% slip ratio and whole contact patch slips. I am not exactly sure it is exactly how it happens, but it is somewhere there in that direction. It is confusing to me when it would be situation when tire slip is constant, and when tire slip oscillates with gripping back and forth. I would never believe it could possibly get anything else but constant sliding when car is almost stationary and rear wheels spin at roughly 110km/h, but you never know. It is weird. @Nieubermesch That competition BMW M2 has way too little sharpness in how those kind of tires perform in my opinion. IMO it would be great car to experiment with new tire stuff that S397 brought recently, It is also mostly mechanical grip car, it seems, so tire would be felt more.
