Wilwood's new UL-16 Spec37 rotors have been developed specifically for the dirt late model and open wheel modified racing markets. Their proprietary iron alloy construction withstands extreme temperatures with the highest degree of resistance against distortion, warping, cracking and wear. The new 11.75" diameter x 1.00" thick rotors are available in HD plain-face or GT asymmetrical slot pattern, and the 16 directional curved open-vane, minimal-obstruction design provides ultimate strength and enhanced air flow while reducing the incidence of dirt and debris collection. All this technology built into a racing rotor that only weighs 6.7 pounds.
