★This product includes two each of red and blue 13-12mm double rollers with rubber rings. ★The 13mm roller side supports your car as it whizzes around the circuit, and when it turns the car leans and the 12mm roller takes over. ★In this way, your car gains great stability through corners, aided by the rubber rings slowing the car slightly when it comes into with the circuit wall. ★Screws, nuts, stabilizer balls, a hex wrench and more are included.
