The Wilwood Ultralite 32 curved vane rotor, part 160-2895, is the left-hand disc in Wilwood's UL-32 line: a 12.19-inch, 1.25-inch-thick vented iron rotor with 32 curved directional vanes and a plain friction face. The manufacturer casts it from premium long-grain carbon iron for long wear, high thermal stability, and resistance to distortion, then production-machines it. At 10.5 lb, it targets the lower rotating mass and efficient cooling that sportsman racers look for in a bell-mount rotor, as opposed to a generic plain vented disc.
Wilwood positions the UL-32 for hard-braking dirt track use and rear-axle service on pavement cars, and the manufacturer calls it suitable from moderate-temperature racing through street use. Buyers searching for a 12.19 x 1.25 8 on 7 left-hand curved vane rotor, a Wilwood UL32CV track rotor, or a lightweight 8x7 sportsman brake rotor will find this part matches that profile. Its 8 x 7.00-inch bolt circle, 0.326-inch mounting holes, 6.38-inch lug ID, and 8.56-inch far-side ID are the dimensions to check against your hub before ordering. The manufacturer lists the right-hand counterpart, 160-2894, as a separate part number. Vehicle-specific application was not confirmed, so verify fitment against your hub and hat setup before buying.
The manufacturer's listing marks this rotor as neither balanced nor bedded, so it is supplied as a plain, unbedded casting.
The manufacturer lists 160-2895 as the left-hand (L/H) rotor. Its right-hand counterpart, 160-2894, is listed separately, so you will need to order the correct side for each corner.
Wilwood files the UL-32 curved vane rotor under its hat (bell) mount rotor category, so this disc is designed to bolt to a separate hat rather than directly to a hub. Confirm that your hat matches the 8 x 7.00-inch bolt circle and the 6.38-inch lug ID before you start. Because the rotor is sold as a left-hand part, mount it only on the left side. Check that the hat and rotor are aligned and that the faces run true before you bed the pads. Verify torque specifications and any required hardware with the manufacturer, since no official install sheet was located during research.
