RayGun Technology allows you to choose the number and location of rotors you buy (front or rear) based on your individual needs. We provide single and dual-disc applications for the client who only wants to replace front rotors. We also offer the choice of buying only a rear rotor. Of course our most popular option is to buy a complete set of RayGun Rotors to replace all their rotors, pads and mounting hardware. We offer complete sets for either single front or dual-front plus rear disc applications.
