Hello Steemers ;-)
Yesterday I was talking to bring you with me in the car during race or training. Here you are some old video from 2010 and in my next post will share current one from 2016. In these two videos you can compare the difference in power, speed and skills developed in 6 years .
In year 2010 205/50 R15 tire managed to last around 10 minutes, nowadays 265/40 R17 tire last less than 80 seconds in full throttle run for a race or qualification lap.
