The Wilwood Rotor-UL32CV Vented Iron-RH, part 160-2894, is a right-hand 12.19-inch vented iron brake rotor from the brand's Ultra-Light UL-32 line. It uses a 32-vane curved directional design, which the manufacturer says gives an efficient balance of cooling and lower rotating mass. The rotor is 1.25 inches thick, runs on an 8 x 7.00-inch bolt circle, and has a plain face. Wilwood says the UL-32 rotors are production machined for sportsman racing. Compared with a stock rotor or a generic replacement, this rotor is aimed at hard-braking dirt track use and rear-axle service on pavement cars, where cooling and weight matter. Shoppers searching for a Wilwood 160-2894 right-hand rotor, a UL32CV 12.19 x 1.25 8 on 7 vented iron rotor, or a 32-vane curved vane directional rotor for sprint or sportsman builds should check the bolt pattern and hub I.D. before ordering. The manufacturer's install guidance also matters for hat-mounted setups, so plan for proper hub prep and bedding.
This part is designated right-hand (RH). The manufacturer lists part 160-2895 in the same Ultralite family with a matching plain face and the same 6.38-inch lug I.D. and 8.56-inch far-side I.D. Confirm the side you need before ordering.
The manufacturer describes UL-32 rotors for hard-braking dirt tracks, rear-axle service on pavement cars, and sportsman racing. It does not specifically call out street use for this part, so check with the manufacturer before using it on a daily driver.
Yes. The manufacturer's pad and rotor bedding procedure calls for several light stops to build heat, followed by 8-10 hard decelerations from 55-65 MPH down to 25 MPH. Afterward, the rotor face should show an even burnished finish.
This is a moderate-difficulty job for a home mechanic with a torque wrench, a wire brush, and a rotor-to-hub fastening kit. Wilwood's assembly sheets for its hat-and-rotor kits say the hat must sit flush against the axle hub, or excessive runout can result, so clean the hub of rust and casting burrs first. Use three lug nuts, finger tight, to hold the assembly while you install the caliper. Owners on user forums report that rotor-to-hat bolts can back out, so use fresh threadlock, torque to the value in the instructions for your kit, and consider safety wire through the bolts. Check the lug and far-side I.D. against your hub before mounting. Finish with the bedding cycle described above.
