Calculate values such as rolling circumference differences, speed deviations, changes in ground clearance, tire diameter, rim width, track width changes or the use of spacers for adjusting the offset (ET calculator) and find out which tires or wheels are best suited for your vehicle. You will also receive a helpful graphical representation.
It handles standard video and audio files well. The screen recording feature is present and functional for basic lesson capture, though it lacks the higher definition options found in newer screen recorders.

Note the difference in rolling circumference:
Rolling circumferences are generally approved in the range +1.5% und -2.5% g. Please check with the responsible inspector beforehand.
