The Wilwood Rotor-UL32 (part 160-0471) is an 11.75-inch vented iron brake rotor from the brand's Ultralite 32 Vane Rotor line, a 32-vane design built for lightweight racing brakes. The manufacturer lists it as a plain-face rotor with a 0.81 width and an 8 x 7.00 bolt circle, and it sits in the brand's Hat (Bell) Mount Rotors category. That makes it a fit for a dedicated race hub or dirt-track build where a hat-style rotor is the goal, not a street-grade swap. Buyers choosing it over a generic cast rotor are usually matching a specific bolt pattern and vane layout, so confirm the hub before you order. Search terms for this part include Wilwood 8x7 hat rotor, 11.75 x 0.81 vented iron rotor, and Ultralite 32 vane rotor 160-0471.
Check the Lug I.D. 6.38 and Far Side I.D. 8.34 dimensions against your hat and hub before fitting, since the lug I.D. determines how the rotor clears the hat. Because this is a two-piece hat-style design, you will need a compatible hat and mounting hardware in addition to the rotor. Confirm fitment with the manufacturer's application chart, as I could not verify a specific vehicle list for this part.
