eXcelerate Double Stuff inserts were designed for when track conditions become ultra sticky. The larger outside diameter of the insert fills the body of the tire to keep the tire from "wadding" up at the intital launch. This larger outside diameter also contributes to more MPH on the top end.
Double Stuff inserts are available in several width and firmness options to taylor your set up to different track conditions.
Double Stuff inserts fit eXcelerate and other other brands of 2.2/3.0 short course style wheels/tires.
