Product Details

StopTech Sport Slotted Disc Brake Rotors are engineered as one-piece replacement brake discs that retain OE-style fitment while adding performance-focused slotting. For Mitsubishi Montero Sport front left and Mitsubishi Montero front left applications, this rotor uses a 6-bolt mounting pattern, a 108 mm bolt circle, and a 87 mm center hole diameter. The vented, straight-vane design supports heat management during repeated stops, while the slotted face helps reduce glazing and keep the pad surface working consistently. The 126.46040SL rotor is a practical upgrade for drivers who want a replacement rotor with added braking response and corrosion resistance.

Common Brake Issues This Rotor Can Address

• Brake pad glazing that reduces initial bite
