Let me start by saying I've installed dozens of brake rotors over the years, and the Raybestos 680181R definitely stands out in terms of build quality. The first thing I noticed was the rotor's substantial weight and smooth machining - no rough edges or casting imperfections here.

During installation, the rotor slid onto my hub with perfect alignment (after I double-checked the part number, unlike one reviewer!). The vanes between rotor surfaces allow excellent heat dissipation - I tested these on mountain roads with heavy braking and experienced zero warping or vibration.

One minor gripe: The protective coating takes some aggressive braking to fully wear off. For about 50 miles, my brakes felt slightly grabby until the coating completely burned away. After that break-in period though? Buttery smooth stops every time.

Pro tip: Triple-check your vehicle compatibility before ordering. While the quality is OEM-grade, fitment issues (like one reviewer experienced) can happen if you don't verify the part number against your specific make/model.

After 3 months of daily driving including some track days, these rotors show minimal wear and absolutely no pulsation. For the price point, they outperform many premium brands I've tried. Just remember - measure twice, order once!
