Weight with Touring package...
 

What's the difference in weight between the base and the touring package?

Not enough to worry about ;)

I noticed the Bose system includes 2 subwoofers. I figured this would be where most the weight would come from...

But does anyone actually know the weight difference?

The 2 subs weight maybe 10-15lbs in the case.

No more than 50 pounds according to Nissan USA, your weight is probably a bit from the subs (10 pounds) and the rest would be the added electronics for bluetooth, heated seats, etc.

Seeing you are not adept enough to find the the Nissan site, here's your weights!

Curb Weights (lbs) 370Z™ 370Z™ TOURING NISMO 370Z™
Manual transmission 3,232 3,278 3,300
Automatic transmission 3,269 3,314 N/A
Weight distribution 54/46 54/46 54/46

ouch!

Ok, thanks.

Actually, my only internet right now is my iPhone. So websites such as Nissan are not very iPhone friendly. That is why I asked the question here.

So this is off topic but I guess better than starting a new thread...
How does the Bose system sound? I currently have a 350z touring and the Bose is ok but not great.

Bose is bose, it will be the same probably as in your 350z. Might be slightly different as the car internally is different and the speakers would be an "upgrade."

I believe the Bose in the 370Z is better then the one in the 350Z....

370z bose is far better than 350z but it is still bose....

Cool, I think I could do without the leather, but the real selling point of the Touring package for me is the Bose system.
I have a feeling the 4 speaker system in the Base model sounds like complete garbage, and that would bother me if I was spending $35k for a new car...

Interesting by how much tastes vary. :)

I've never been much of an audiophile, so even crappy sound-systems don't bother me. As weird as this will sound to some, the biggest selling-points of the Touring model to me are (in no order) aluminum pedals, suede[ish] door-panels, and the use of two out of three of the otherwise blank switches (I hate when car manufacturers do that).

I wish Nissan made navigation an option for the Base as well as the Touring, or perhaps included the screen on all models and made the navigation function optional (ala G37).

Yes, I agree. It is nice to have a screen regardless of NAV being optioned or not.

Also the SOW system in the G is really not bad. It may not have the bass required by the bass junkies, but all in all it's a pretty good system for OEM and a major leap from the G35s.

The 370z Bose is a very minor improvement over the 350 from what I was able to ascertain

I'm not a huge audiophile myself... But it just seems if you're gonna spend $30k on a new car, why not spend the extra $4-5k for the Touring model and overall have a nicer vehicle. The leather itself adds a richer, more luxurious feel.

For me, it's about the overall package from the factory. Sure you could get a much better aftermarket sound system than the Bose but I've never been too big on aftermarket parts with the exception of a few performance mods.

I like a car that has a little bit of everything from the factory.

the exact weight diff between the base and touring is 82lbs.

I have never been one for leather; like the pure sports car feel... r a w. Give me the base; I will switching the seats out anyway....

And give me an LSD thats worth a shyt! Quaife, hurry your arses up!

Haven't really heard much about the stock LSD other than a few comments similar to yours. Care to eloborate why you consider it "shyt?"

Viscous LSD's are bottom of the line when it comes to LSD's. They lose efficiency the hotter they get and often fail when put under a heavy load. A few people here have had track failures, in particular DD Motorsports track car, check out their lap times at Buttonwillow posts.

Have a read: The viscous lsd is generally simple because it relies on hydrodynamic friction from fluids with high viscosity. Silicone-based oils are often used. Here, a cylindrical chamber of fluid filled with a stack of perforated discs rotates with the normal motion of the output shafts. The inside surface of the chamber is coupled to one of the driveshafts, and the outside coupled to the differential carrier.

Half of the discs are connected to the inner, the other half to the outer, alternating inner/outer in the stack. Differential motion forces the interleaved discs to move through the fluid against each other. In some viscous couplings when speed is maintained the fluid will accumulate heat due to friction. This heat will cause the fluid to expand, and expand the coupler causing the discs to be pulled together resulting in a non-viscous plate to plate friction and a dramatic drop in speed difference. This is known as the hump phenomenon and it allows the side of the coupler to gently lock. In contrast to the mechanical type, the limiting action is much softer and more proportional to the slip, and so is easier to cope with for the average driver.

New Process Gear used a viscous coupling of the Ferguson style in several of their transfer cases including those used in the AMC Eagle.Viscous LSDs are less efficient than mechanical types, that is, they "lose" some power. They do not stand up well to abuse. In particular, any sustained load which overheats the silicone results in sudden permanent loss of the differential effect.[4]They do have the virtue of failing gracefully, reverting to semi-open differential behaviour. Typically a visco-differential that has covered 60,000 miles or more will be functioning largely as an open differential; this is a known weakness of the original Mazda MX-5 (a.k.a. Miata) sports car. The silicone oil is factory sealed in a separate chamber from the gear oil surrounding the rest of the differential. This is not serviceable and when the differential's behaviour deteriorates, the VLSD center is replaced.

Basically a gear driven LSD like a quaife is the best and most reliable. Nissan really screwed the pooch on this one.
