StopTech Sport Slotted Brake Rotors are 1-piece direct replacement brake discs for your factory brake system and stock calipers. The 'SL' (Slotted Left) designation indicates this is a directional rotor intended for the front driver side. These rotors feature specialized vacuum-cast slag-free metallurgy and precision-machined slots that improve braking performance by wiping away debris and preventing pad glazing. The premium E-Coating finish provides long-lasting corrosion protection. This item includes: 1x StopTech Slotted Sport Front Left Brake Rotor (P/N 126.44129SL). For a complete front axle set, this must be paired with the right-side rotor (P/N 126.44129SR).
