USPKS and Route 66 kart series announce mandatory drop down nose cone system.
This is a very simple system that can be added to any kart, for a minimal cost. It has been used successfully in Europe for several years and it has reduced contact between karts significantly. The drop down bumper doesn’t actually drop down, but it “pops” loose if there is excessive contact with another kart. Once loose, the driver can continue on, but a penalty will likely be assessed at the conclusion of the race.
