Weight Reduction
i tried to remain as stock as possible, but lost a few pounds in jack and tools, rims, brakes, battery, and exhaust. car weighed in at about 3100lbs with a half tank. not too shabby, jeje.

light seats is an excellent idea. i would do it too. stripping the interior is a little on the caotic side, if you ask me. and the gain is negligible for the sacrifice you make. i would only change the hood if i were to go turbo to extract some of the heat generated.

I have to politely disagree. It is made of quality materials, however when it comes to improving overall response and handling.... you should spend an equal amount of effort towards both power and weight improvements. Depending on what it is that you want to do with the car. We can take a 60lb door, and bring it down to 20lb's, and the roof (assuming you might do track) another 45 to 50lb's. The trunk, about 70lb's off is possible. Here is a prototype dry carbon hood just out of the mold for our sponsored race car. It weighs 9lb's, which is 15lb's lighter than the stock aluminum hood. Throwing HP at a car does improve acceleration. But weight reduction will improve braking time, reduce tire wear, improve acceleration and allow for later braking in turns. These are all benefits of weight reduction, HP increase improves just acceleration.

I had an Altima before my Z and it was light because it was made out of cheap materials. Sheding a few lbs from the wheels for the amt that you are going to spend on it too much for little gain in quickness.

um, nice
and subtle advertising there 
. plus there is no way i woudl ever sacrifice safety on the street to save a few pounds that will not matter anyway, especially the doors. for a car that is strictly used for track purposes only, yes i see weight reduction being important. but not on a street car.

I would probably start with lighter rims - unsprung weight is a big thing to get rid of. I would also probably go to a lighter weight battery and lighter exhaust. You could get rid of 100 lbs right there without sacrificing any comfort/convenience.
Not advertising, not spamming. These hoods are not available to you folks i am afraid. Just for racing teams. That is why they are dry carbon and 9lb's. 
Don't be so jaded about people showing parts on a thread. Doesn't mean it's for sale. There wasn't a price tag with it.
You guys asked about weight reduction and what was possible. I just replied to it.

and/or the vehicle that hit you sitting in your lap.

I would be worried about cf shards cutting me up

Sooo the windshield shattering is not a concern? Just a carbon hood huh? lol.... you guys are cracking me up. You oem hood is aluminum ! And shattering CF? CF will only "snap" at the stress point. It doesn't shatter like glass if that is what you think. Your typical market CF hood has one layer of 6 or 12 ounce carbon fabric. The rest is fiberglass and resin.
