Above is the 'Car Roll Center Analysis' screen showing Left Roll Center temperature difference. Left Roll Center is the difference of Left Front and Left Rear tire temperatures. Compairing the front to the rear tire temperatures indicates if the front and the rear roll centers are in sync. The difference tire temperature on each side should be about the same. When the difference is closer to zero the roll center balance is best. Having all 4 tires more equally loaded they produce more grip which results in a faster more consistent car throughout the race.
