StopTech sto127.44090R - Drilled and Slotted Sport Rotor

StopTech Drilled and Slotted Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique cross-drilling and slotting aids with heat and brake dust dispersal; prevents glazing of the pads; adds bite and improves wet and dry braking performance. Built to last; the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation; better crack resistance and increased performance. Premium e-coated rotor with advanced metallurgy that greatly reduces pad squeal. Especially effective with higher friction; European style brake pad compounds. Drilled & Slotted for increased bite; improved looks and better performance Premium e-coated rotor with advanced metallurgy that greatly reduces pad squeal; Especially effective with higher friction; European style brake pad compounds; Added Molybdenum and Chromium to resist rotor cracking 1998 - 2005 Lexus GS300, 1998 - 2000 Lexus GS400, 2001 - 2005 Lexus GS430, 2001 - 2005 Lexus IS300, 2002 - 2010 Lexus SC430

The StopTech sto127.44090R Drilled and Slotted Sport Rotor is a one-piece direct replacement brake disc designed for factory brake systems and stock calipers. Its cross-drilled and slotted design helps disperse heat, brake dust, and gases while supporting increased initial bite and improved wet-weather response.

The rotor features a black e-coating on non-friction surfaces for corrosion protection and advanced metallurgy intended to reduce pad squeal. High-carbon metallurgy in most applications supports quieter operation, improved crack resistance, and consistent performance. Added molybdenum and chromium help resist cracking caused by thermal stress, while double-disc grinding provides a consistent friction surface.
