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.
