The 370Z Weight Reduction Thread

wstar · 08-20-2012, 03:45 PM

Sounds kind of hard-core to me. I guess if you were having your engine completely rebuilt and fine-tuned for balance anyways, you may as well try something gutsy like that

I wouldn't tear the engine apart just for the lightening though.

anybody look at Litespeed Racing? its basically a Titanium resonated straight pipe they claim exhaust weighs 14lbs excluding the Y-pipe as far as i can see sent them an email. its pricey 3600 or so but -40lbs and adding 14whp and 16trq (Dyno sheet on website) could be a recipe for success. Loud i would bet though good for a track car haha 370z Full Titanium Race Exhaust sounds pretty good as well

Yes, I've been to the litespeed site. They also advertize here. The 14 whp I believe was on a Nismo, so it might be more on a base coupe.

I picked up a Siebon dry carbon hatch. Will be interesting to see weight savings with this piece

Please post both weights, Siebon and stock, after you weight them. How much for the dry carbon hatch?

Were those long tube headers that replaced both the stock headers and the stock cats?

They were short piped headers. Just replaced the manifold.

No, short tubes

kcquinn49 · 11-04-2012, 12:37 PM

thanks for the quick reply. I checked this thread for weight of the stock header and couldn't find it. I only found that the Fast Intentions long tube headers, as a pair, are 17 pounds lighter than the stock headers and cats that they replace.

What was the weight of the stock headers?

Extra pound or so you can shed without really altering the look of your car (for those of us who aren't track monsters like Spohn, Mike, or wstar, lol)

For all the Nismo guys... Removing the front and rear body dampers saves 8.4lbs. I can't hear/feel any noises/vibrations or anything after I removed them.

Our standered cars don't have them so I see no reason why there absolutly need. I feel if you have most suspension upgrades (coilover/springs, sways) they more than make up for the body dampners.

I really think now I'm going to remove the crash beam up front.

i will have to look into it, but some of the past models of the Z have had fiberglass crash beams in non-US versions. The 300zx has a 100% fiberglass Crash beam on the JDM models, but has a heavier, aluminum version in the US that meets the 5 mph DOT crash test requirements.

I will check tomorrow to see if there are any differences.

Update:Nevermind. The JDM bars are indeed different. But they actually appear to be heavier duty than the US models. They have some extra crash beam protruding off of it.
