Front Left Slotted Brake Rotor, StopTech - E82 135i, E82/E9X Performance Brakes
Performance slotted rotor is a direct alternative to BMW part #34116786392 and 34116778647.
338x26mm rotor fits stock E82 135i front brakes.
Also fits the factory BMW Performance sports brakes installed as a retrofit on E82 128i and E9X 325i/328i models.
This is a Left Front rotor.
This rotor is the same specs as what was originally used in the sports brake retrofit kit used on 128i/325i/328i models.Excessive heat can cause resins in your brake pads to vaporize or "outgas." As the brake pads wear, the used friction material turns into a fine dust. This boundary layer of heat, gas, and dust builds up between the pad and rotor surfaces and inhibits performance. The slots in StopTech Sport Slotted Brake Rotors are machined into the rotor and help evacuate gasses and dust, shed heat, and keep the brake pad surface clean. And in wet, raining conditions, the slotting helps push water off the braking surface for better stopping power. StopTech also uses a special metallurgy and directional cooling vanes to improve high temperature performance.
StopTech is an enthusiast-driven manufacturer of replacement brake components, brake upgrades, and Big Brake Kits. Since their beginnings in 1999, StopTech has operated under a "better than OE" approach to design and manufacturing. Most obvious is their electrostatic anti-corrosion coating that signaled the end to cheap, aftermarket rusty rotors. Under the surface, every StopTech slotted rotor is CNC machined from a High Carbon blank disc. The High Carbon approach results in a brake disc with greater capacity for heat absorption. This results in less deformation of the braking surface, aka "warping", better resistance to surface cracks, and greater performance overall.
