Racing Optics tearoffs are a laminated tearoff solution for dirt and pavement forms of racing eliminating the need to apply individual tearoffs. The laminated technology creates a distortion-free optical lens. The XStack™ is a stack of 10 laminated tearoffs that are each 2mm thick. Each package contains 3 stacks of 10 tearoffs for a total of 30 tearoffs. The large tab design makes pulling the tearoffs easier and is especially beneficial for dirt racers. Compatible with the HP7, RS7C LTWT, RS7SC LTWT, RS7 Carbon, RS7K Carbon, RS7, RS7K, KC7-CMR Carbon, and KC7-CMR.
