Description

StopTech 128.45086L Drilled High-Carbon Brake Rotor Front Left for Mazda 3, Mazda 3 Sport and Mazda CX-3.

StopTech Drilled and Slotted Sport Rotors are 1-piece direct replacement brake rotors for factory brake systems and stock calipers.  These rotors offer significantly improved braking performance over the OEM rotor. 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. 

Drilled/Slotted rotors by StopTech are by far the best-looking quality High Carbon Brake Rotors on the market. Their dipped e-coating process still looks new after years of use and is the most impervious coating against environments that use salt and brine on the roads. Ideal for top-end Euro cars to sport-driven enthusiast vehicles from around the world. Looks are stunning inside open-style wheels. Sold each.

StopTech® 128 High-Carbon Cross-Drilled Rotors

E-Coated Finish
Most StopTech® Rotors are finished with black e-coating on both sides of the hat, inside the cooling vanes, and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt-water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these areas can lead to installed lateral run out issues.

Power Alloy Metallurgy
Power Alloy metallurgy is an exclusive feature of many StopTech® rotors. In specific vehicle applications, StopTech works with foundry partners to increase the molybdenum or carbon content of the castings, and to carefully control the cooling rate during production to reach targets for hardness and tensile strength.

Cooling Vane Design
Nearly all StopTech® 1-piece rotors have unique slot or hole patterns for the left and right sides of the vehicle. For these directional patterns, straight vane or pillar vane rotors are used to ensure that a drilled hole never touches a cooling vane.
