ARLEN NESS Spider Rotor Adaptor — 320 mm rotor, 3.25" bolt circle, Red

The Spider Rotor Adaptor is a CNC-machined rotor carrier for floating (spoke-mount) brake rotors on cartridge-type wheel hubs. Forged and precision machined, its coped cutout design follows the sculpted lines of cartridge hubs to reduce weight while maintaining strength.

• Accepts a 320 mm spoke-mount floating rotor to form a lightweight, high-performance rotor assembly.
• Mounts to standard 5-bolt HD-type wheels with a 3.25" bolt circle.
• Allows use of factory touring 320 mm front spoke-mounted floating rotors on custom wheels.
• Designed for use only on wheels with cartridge-type wheel hubs.

Precision machining ensures consistent rotor alignment and dependable brake performance. Installation requires standard 5-bolt mounting hardware and proper torque specifications; professional installation is recommended.
