They are generally softer and quieter, but wear faster and produce more dust. They are suitable for light driving but not recommended for the performance-oriented G37S due to lower heat tolerance and fading under hard use.
-
Semi-Metallic Brake Pads: Composed of 30% to 65% metals like steel, copper, or iron mixed with organic materials. They offer excellent braking performance, good heat dissipation, and durability. However, they can be noisy, produce more dust, and may wear rotors faster. For the G37S, especially if driven aggressively or in varied conditions, semi-metallic pads are a solid choice for their strong initial bite and value.
-
Ceramic Brake Pads: Made from ceramic fibers and filler materials bonded with copper or other metals. They are known for quiet operation, low dust, consistent performance across temperatures, and long life. While typically more expensive, they provide a good balance for daily driving and occasional spirited use in the G37S. They are less abrasive on rotors, reducing long-term maintenance costs.
-
Performance or Track Pads: These are specialized pads, often semi-metallic or ceramic composites, designed for high-temperature use on racetracks. They may require warming up for street use and can be noisy or dusty. Only consider these for the G37S if you frequently engage in competitive driving, as they can compromise comfort for daily commutes.
