Policar track is rapidly becoming the system to judge all others. Designed with racers in mind the track features a high grip surface, which will even allow you to run slot cars without magnets, so you can power slide round the corners. It is already slightly wider than the more known brands but can benefit even further with clip in borders. There are currently 4 different radius curves on offer along with various length straights so you can build the track of your dreams. Other useful accessories are also available.
