From an SAE article: http://articles.sae.org/10472/
------
The FNC process lays down a 10-µm-thick transfer layer across the entire rotor surface, including the center “hat” section and inside the central cooling vanes of ventilated rotors. (Ten microns is roughly 1/10 the width of a human hair.) The resulting friction surface is significantly more durable than that of a rotor without the FNC treatment, while remaining virtually impervious to corrosion and rust.
“We expect FNC will double rotor life from the current 40,000 miles, to 80,000 miles, before it needs to be ‘turned’ [machined to regain factory-spec lateral runout and surface finish],”.
-------
Hard to imagine a 10 µm coating is going to significantly increase rotor life on the track. Well before you can see or feel any changes to the braking surface that coating is long gone. From what I've seen with my non-nitrided rotors, that will be by the end of track day 1.

10 µm is the thickness that it adds, but nitriding is more of a surface treatment than a coating, the hardening effect runs deeper into the metal than that. My point was just that for even money, there's no reason to not get the OE grade nitrided rotor. But hey, it's the internet, argue away...

I've had these on my last 3 HPDE days and have worked great!

Right now on sale for $99 for the front set.
I don't recommend buying the rear set.....mine did not fit at all over the emergency brake pads.....so just stick with the fronts.
