Anything from the *Stealership* or Nissan site is going to be marked up to begin with. Take a look around and you can find the Nismo pads (and generally everything else) for a lot less.
Examples:
Nismo: Z1Motorsports.com, Front and Rear set for $166 before Tax/S&H
EBC Yellow: Autoanything.com, Front and Rear set for $276 before Tax (S&H includud, but upgrade to overnight for +$14)
Projectµ: ConceptZPerformance.com, NS F&R $176, B-Force F&R $222, Club Racer F&R $275 before Tax/S&H
*Note* I really appreciate the Projectµ site for listing it's temp and friction coefficient ranges as well as the standard spider chart on the relative stats. (

As for me, I'm probably going to pull the trigger on the Nismo pads because of that OEM+ status. If they don't meet my expectations I'll try Projectµ because they seem to be documented the best and are Japanese. If all else fails, EBC Yellow to see if the Hype is true
