The Martin Custom Products 10″ Brake Disc is designed for the 6-Bolt Sprocket Carriers used on racing go-karts and lawnmowers. 

We highly recommend using the 10-inch brake rotor for racing lawnmowers if they have the ground clearance to do so. The 10-inch brake disc adds mechanical leverage to the brake so that length increases leverage on a breaker bar, which gives the brakes more potential for stopping and locking up the rear wheels. Smaller brake rotors such as the standard 7.125″ diameter disc may not have enough leverage to slow heavier, faster machines, which is more crucial for machines that do not run a front brake setup that helps the rear brake slow down. 

Your race machine’s ability to slow down quickly and late into a corner can increase your lap times, putting distance between you and the driver behind you and making aggressive overtaking without running over your competition.
