I'm looking for Spirit R brake rotors, I checked out this site and it doesn't seem like they have it based on searching that part number you gave above. Any idea what I did wrong?

The Spirit R cars had larger brake rotors. So if you have those brakes you have to find the appropriate rotors. Stock FD rotors won't fit.

There should be two part numbers as there are front and rear rotors. The one you posted is that for the front or rear? I have RS brakes which are the same calipers, but I want the Spirit R cross-drilled rotors.

Rotors from JDM FDs that came with factory standard 17" wheels = 314 x 32mm. Apparently also contoured slightly to suit the unique piston setup in those cars (as the leading and trailing pistons are different diameters)
The extra thickness is IMO where you see a big benefit from the upgraded rotors / calipers
Spirit R rotors = as above for 17" wheel cars but are cross-drilled from the factory
Now, cross drilled ones are more prone to cracking (I've seen them crack around the holes on a friend's Spirit R after 1 track day!). But they certainly look nice.
The plain 314mm Mazda ones from the Type RS are much better quality than your average aftermarket large rotora and will last a long time.

What I meant was, if Wilwood/Brembo/etc made a 314x32mm rotor then could you not just use those? As opposed to searvhing far and wide for the mazda rotor.
I definitely agree on the drilled rotors!! I want to say I heard that a lot depends on if the edges are beveled or not, with the non-beveled being much more prone to micro cracking.
That, in and of itself, almost makes me want to lean towards slotted only in the future.
