Wilwood Ultralite HP rotor, 32‑vane design, measures 12.19" diameter by .81" width with a 6 x 5.50 bolt circle. The Ultralite HP construction reduces unsprung weight while maintaining cooling through the 32‑vane internal design, making it suitable for applications where rotor diameter and bolt pattern match these specifications. Use it when replacing or upgrading to a lightweight, vented rotor.
