StopTech Sport Slotted Cyro brake rotors are one-piece direct replacement brake discs for factory brake systems and stock calipers. These rotors undergo a deep cryogenic treatment that realigns the molecular structure of the metal to increase durability and resistance to thermal cracking. The slotted design helps wipe away debris, prevents pad glazing, and improves wet weather response. Includes: 1 x Front Left Slotted Cryo Rotor (P/N 126.40094CSL). Features a black e-coat finish for corrosion protection on non-friction surfaces.
