The fluidamper weight is about the same as the stock damper and is of first class design. I ran the same design in my small and big block chevy drag engine. I remember the rod and main bearing I pulled out of engines that ran a bad harmonic balancer.
I never broke a crankshaft in the chevy engines twisting over 9400rpms with the dampers in place. The dampers did show a major incress in HP at higher RPMS on engine dynos. I did always run a heavy flywheel in my strip cars,because I needed drivabilty. For my G35, I would pefer more flywheel mass and putting UD pullies on went the wronge way.

The spacer is one of the best gains/$ mods you can do.
As for cams, they do help but the gains/$ are quite low. Most good cams will cost you $1k and the install is not easy.

I would go with the motordyne 5/16" spacer. Intense motorsports has a sale on them right now over in the vendor classifieds.
You can change your rear differential gearing. It is a great mod! Is your car a MT or AT? The AT's have ~3.3 final drive, the MT ~3.5 and on either one you can go up to a 3.9. You may loose your cruise control, some do some don't, it's luck of the draw. You will also rev a little higher on the freeway in your final gear so your mpg will go down ~1-2, most people report 1mpg.

The under pulleys are lighter than stock. Also the altenator pulley is the same size as the stock. The other two pulleys are smaller (crank and AC). I have been told you can feel the difference when you install them. If your engine is NA you can gain 10HP and if your FI you can gain 15HP extra.
