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.

DIY: Weight reduction/Fix hatch not opening issue

MJB · 11-18-2012, 01:03 PM

I took out the interior plastics and yesterday minus the center console, the dash, and the roof liner. I was able to shed 66lbs, thats including the carpet and radio as well. Add the spare tire (35lbs), passenger seat (39lbs) and that puts you at 140lbs. Which is awesome because all that stuff can be put back in within a couple hours

. I'm sure the roof liner(with airbags), center console and parts of the dash can get you another 30lbs or so.

At one point I took out the interior roof stuff as an experiment temporarily. The headliner, the super-duper-garage-door-opener-mirror and its wiring, the upper airbags, etc. Drove it around like that for a week or so. It's not a ton of raw weight, and it could've all been in my head, but I swear I could feel the difference in the handling (and that was after most of the rear interior was stripped out like MJB's talking about). My theory is that being so high up on the car, the weight up there counts for more than you'd think. Ended up putting it all back for now because the car's still on the street

That's good info. THanks. Was it hard to remove the liner?

wstar · 11-19-2012, 07:10 AM

It's pretty easy to remove all the inner roof stuff. Having the seats out helps a lot though

Shamu · 12-02-2012, 05:56 AM

In addition to weight for us tall guys having headliner out gives us much needed helmet clearance.

The problem I find with lightweight wheels is that they just don't look as good as full size ones. Low profile tyres weigh less but are quite uncomfortable on the road

SteveBad · 02-20-2013, 07:17 PM

Do we really need TWO horns ?

From the shop manual:

Horn (HIGH)
1. Remove the fender protector LH (front). Refer to EXT-23, "FENDER PROTECTOR : Exploded View".
2. Disconnect the horn (HIGH) connector.
3. Remove the horn mounting bolt, and remove the horn (HIGH) from the vehicle

What till you guys see what I'm doing this weekend. No one has cut weight here.
