About Weights
Choose from a wide range of lead-free weights available in various styles and shapes to meet your specific racer needs, such as aerodynamic, tungsten and/or incremental. Tungsten weights are 1.7 times denser than lead, and their incremental design allows you to weight your racer in exact 1/16 ounce increments. Other incremental weights are scored to allow you to break off sections, even on race day.
