In kart racing driving skills are the most important factor to being able to have fast lap-times.
Once you have mastered kart racing driver skills then you will benefit from having a great kart set up. This set up includes using the best brake set up to ensure you are taking advantage of late breaking in those corners.
Getting thru the corners on a racetrack fast is one of the most if not the most important aspects of kart racing.
Having the right brake set up from Wild Kart or Righetti Ridolfi will ensure the highest level of quality and performance you can get on your 2 cycle or 4 cycle kart.
