FI LTH's are coming in June which will drop another 17lbs up front. Seats will drop another another 23 or so lbs, that's the next major interior thing. Front 2-peice rotors will drop another 14lbs (rolling, unsprung) weight, not sure on the back, probably less, let's say 5. So that ballparks me around 165 lbs down once I get to that point in my progress. After that, it really is mostly stuff you'd only do on a more dedicated vehicle: killing the radio, the A/C, all the interior plastic, extraneous wiring, etc, etc. I'm not doing any of that so long as I'm regularly driving the car on the street. Edit: BTW, for ballpark referencing what weight reduction is worth, since our cars are in the ballpark of 10:1 weight:bhp ratio, I generally go by that. E.g. dropping 105lbs is worth about the same as adding 10 horsepower just in terms of raw acceleration potential. Of course that doesn't factor in any other benefits.

one thing that DOESNT make your 370z lighter is adding a Seibon TS hood. I immediately noted that this hood was at least a few pounds heavier than the stock one. It was noticable enough to detect just during lifting it for installation.

Wstar- sounds like a good start. I reduced about 10lbs from exhaust, 6lbs per corner (static) on my wheel/tire setup so I saved about 110lbs right there. everythig else about stock.

My first thought based on the thread title was "just chop off your left arm"
Seriously though, the easiest way to drop weight is thru the exhaust components. FI claims 16lbs reduction by replacing the oem manifold and cats with LTH and a 17lbs reduction by replacing the CBE so that's pretty significant. I'm sure other aftermarket exhaust setups are pretty similar in weight savings too. |

Just pointing out what should be obvious. The thread has a title and a pretty clear set of objectives. Only one person actually responded with some factual information on the topic at hand, the rest is just ******** "question the questioner's motives and reasoning" crap (which I wouldn't mind so much if I didn't have to go back and point out what should be obvious from my journal thread, or even from the rest of this thread).

...and if i really wanted to put snark in my comment, which i didnt, i wouldve stated that i gained more total weight savings without really trying from my wheel/tire setup than you did with all your unsprung and spurng combinations. |

Good luck with your trolling?
Were you going to answer the question about 6x4 = 100? I've never seen One True Definitive answer on how to convert rotational and/or unsprung weight into some kind of equivalent in sprung weight. |

First off, I'm going to admit I'm not the most helpful person when it comes to keeping track of the weights. Partly because I don't have an accurate scale but mostly I'm too excited to get the new parts on I forget to weigh them first. Luckily I still have all the shipping boxes and shipping weights so I can do the math. Anyhoo...
Nothing from any vendors? Bummer... Since I am also very curious about shaving off some weight, especially the front I'll put this out there: the stock strut brace seems pretty light but I'd be curious to know how much a $2400 titanium one would be. If you want an 11 lb exhaust (y-pipe ans single exit) you could do the titanium amuse r1000. Only $4k I'm curious if you did a trade between narrow lighter wheels and wider one with more grip. I personally just went with the widest then tried to minimize the weight. How about lightweight lug nuts? They'll help the unsprung mass but won't do much for rolling resistance. Rays short type are 17g each. 0.75 lbs for all 20 so ~2.25 loss compared to stock listed in RCZ's thread |

Belsavis: Yeah I'm using lighter lugs already, and the 2pc brake rotors are on the way, should be here late next week I think. I guess the timing is good, I can go crazy and kill whatever's left in my current rotors + pads this weekend at the bmw event and then swap in the new setup next week for a fresh start. In the case of the available body parts and things like the Ti strut braces and exhausts, it's just not worth the $$ to me for the small weight drops. What I was hoping I would find from vendors in this thread was that they had reasonably-priced FRP (or similar) body parts that were significantly lighter than stock, but with the thin aluminum on our cars that doesn't seem realistic. I will go ahead and close this thread, since it was so far off track already. I thought it would just die naturally, but here we are |
