Stoptech Racing offers lightweight .810" direct-mount rotors, available in slotted or plain versions with either a curved vane or pillar vane design. These high-quality rotors bolt directly to the hub, and the slotted pillar variant can also be floated using the Stoptech system as required.
The Stoptech 16-plus curved vane rotors are one of the lightest rotors available, weighing in at under 6lbs, while the pillar vane versions weigh approximately 8lbs. The pillar vane rotors are ideal for use on the rear of modifieds and late models and can be used on all four corners to provide a durable yet lightweight option.
It should be noted that plain rotor face is mandatory for IMCA classes other than late models.
