Description
StopTech 126.34145SR High-Carbon Slotted Rear Right Disc Brake Rotor for BMW 228i, 230i, 320i, 328i, 428i, M235i, and M240i.
- A one-piece direct replacement brake rotor engineered to look and perform better behind the wheel
- Slotted design provides the best brake pad bite and stopping power than any other rotor designs
- Cooling vane design offers better cooling capabilities
- Prevents glazing of the pads as it helps wipe away the debris that forms between the pad and the rotor
- Manufactured using a special Power Alloy metallurgy for better crack resistance, quieter operation, and increased performance
- With durable black e-coating finish for superior corrosion resistance
E-Coating vs Other Brands Black Painted Finishes
StopTech Premium 126 Brake Rotors use a unique E-Coating that is a electrostatically applied finish that can withstand more punishment than normal black painted finish. The attached photos show the durability difference when sprayed with brake cleaner.

Split Core Castings vs Side Casting
Stoptech Premium Rotors use an OE Style Symmetric Split Core Casting and vane design which helps your rotor dissipate heat more efficiently than standard side cast rotors. This delivers stronger and safer stopping power.

Raising the Bar on Quality
StopTech uses some of the strictest standards when making their Premium Brake Rotors. All of the Rotors are machine-finished and mill balanced for a smooth finish and vibration resistance. StopTech uses OE Style symmetric split core castings and OE Style vanes on applications that are vented. This helps create uniform heat dissipation, reducing the chances of warping and fade. The StopTech Premium Rotors are then given an Electrocoating or "E-Coating" that delivers long lasting corrosion protection. Most other brands just use a paint coating for corrosion resistance which is not as effective as the E-Coating because the paint easily wears off.
