NAPA Premium rotors are manufactured to meet the strictest physical, safety, and performance requirements and surpass standard models. NAPA uses G3000 material and follows OE specifications for plate thickness and fin design. By contrast, the many low-cost, inferior products on the market deviate from OE design, which often results in brake pulsation.
Unfortunately, there are plenty of inferior products still on the market, and many of them fail to meet metal and machining specifications. Some manufacturers remove material, resulting in thinner rotor plates and, consequently, fewer and thinner vanes. The bottom line is, it’s never a good idea to deviate from OE design.
