No No man, I didn't see any disrespect at all, it's an honest question. I just decided long ago that my comfort was more important and to compensate for that extra weight I started hunting for more power. Of course now I'm completely addicted to 'just a little more'
I don't know if the carpet kits for 280's are different but all the 240 carpet kits I have dealt with were feather light, kind of flimsy and cheap

The other thing is that the Z car has an open hatch area. You get a lot of road and differential noise amplified by that big Tin Drum in the back. Commonly called a spare Tire well.  And the glass hatch reflects any noise forward. I have carpeting and underlay already ( Custom carpets for 280Z ) but I still get an annoying diff whine at certain speeds. Hoping that some DynaMat will reduce the whine somewhat.

It seems to be an inherent trait of the R200... but I suspect I may have a pinion bearing getting a bit noisy. Was supposed to tackle the diff this winter.... but it was too danged cold!! 

I had the same situation on my Third Gen Camaro. Rear hatch glass reflected a lot of diff and road noise. Dynamat in the spare tire well area really cut the noise down.
