• Finished in Yellow powder coat for a distinctive, high-visibility appearance
• Also available in Black and Red powder coat; Type III hard anodize and special powder coat colors available at additional charge

• OEM-matched thickness: 0.79" (20mm)
• Available rotor surface options: plain face or SRP directional drilled and slotted
