ProStop Performance Drilled/Slotted Performance Rotors are precision engineered to meet or exceed OEM performance specifications. Cast to OEM design & SAE J431/G3000 metallurgical specifications. Model # 227. 44108R Features: Feature a signature ""short slot"" design. The slot improves brake system performance by wiping away the debris of used friction material that otherwise accumulates between the rotor and pad. This helps prevent pad glazing. The edges sweeping the pad increase the effective coefficient of friction or ""bite,"" amplifying brake system response to pedal input. Slotted and drilled rotors also improve initial brake response under wet conditions by providing an escape path for water. Exceptional heat dissipation Item Dimensions: 10. 5" L x 10. 5" W x 2" H.
