ceramic vs. semi-metallic
Did some quick research on the net about this. Interesting, lots of conflicting information. Some resources say ceramic last longer, some say semi-metallic. Some say ceramic runs cooler, some say semi-metallic keeps the rotors cooler. Some say ceramic is harder on rotors, some say the opposite. Seems like there is conflicting information on just about every benefit/drawback, except that the ceramic dust is less noticeable.
From the post below, my question would be, has anyone contacted Nissan or a dealer and found out if ceramic pads are or aren't recommended?

"Ceramic pads still cause dust, it's just not black so you can't see it. Besides the lack of black dust, ceramic pads have several benefits that make them worth the extra cost. Here is a snippet from this ARTICLE that discusses the advantages of installing ceramic pads and other brake issues with your vehicle:

'Although first introduced as far back as 1985 on some new vehicles, mass after-market applications for ceramic-based disc brake pads are just now becoming widely available. Approximately 33 percent of all new vehicles, domestic and foreign combined, now have ceramic-based disc brake pads. The newest generation of ceramic brake lining compounds contain no chopped steel fibers or steel wool as found in earlier semi-metallic linings, but instead substitute ceramic compounds and copper fibers. These changes provide modern ceramic-based lining materials the capability of handling today's high brake temperatures with less heat fade, faster recovery time, and less wear on both the pads and rotors.'
Of even more value to brake repair facilities is the ability of ceramic lining compounds to significantly reduce annoying brake noise or squeal, which is the No. 1 consumer complaint relating to brake service. Ceramic compounds dampen noise and move brake pad vibrations to a frequency outside of our human hearing range, 20 Hz through 20,000 Hz. As with earlier disc brake pad designs, some ceramic pad applications may also incorporate other noise-reducing features such as chamfers, slots and insulator shims. One leading after-market manufacturer has gone as far as naming its line of ceramic brake pads "Quiet Stop."
Another positive characteristic associated with ceramic brake lining materials is the absence of visible brake dust, a feature that any vehicle owner with stylish wheels will appreciate. All brake materials, ceramic included, will produce some brake dust. Earlier semi-metallic and organic brake compounds left a brownish black dust on wheels. In comparison, ceramic compounds produce a light-colored dust that is much less noticeable and does not attach itself to wheels.
Although an increase in product cost will more than likely be associated with ceramic-based brake linings, their benefits may be worthwhile for consumers. Based on their own durability tests, lining manufacturers say these compounds will outlast most other premium pad materials by a considerable margin. However, after-market brake pads with ceramic materials should only be used on those applications where the OEM specified a similar formula.
Additionally, you may hear (or see, if online) complaints about poor stopping power with cold brakes. This is typically true about older ceramic pads and ceramic pads designed for racing, but today's consumer grade ceramic pads have great stopping power. In fact about 33% of new vehicle today come stock with ceramic pads. What is important though is that car's rotors are designed for ceramic pads, otherwise the rotors will typically wear faster. Check with the vehicle manufacturer about this."
