That's what I want to do is cut the OEM hood. But UAM might know about the weight of the fenders for the work with them.

All this CF **** is just for looks, no one makes them with weight in mind. Nobody ever posts the weights of their CF products(you have to specifically ask) because there is no weight savings.

That is because companies are making half a$$ parts.
A lot of CF parts are fiberglass or other product wrapped in CF which in ends up weighting the same as OEM parts. Dry carbon will shave a lot of weight, for a hood our sizes in dry carbon should weight in under 10lbs, but dry carbon is very expensive (our hood would cost 2k+).

Agreed... functionally, the market should buy either fiberglass only or dry carbon only...

The fact that CF wrapped fiberglass is what sells, says a lot about what is motivating buyers

I have heard that seibon will occasionally produce its parts in fiberglass only... haven't seen those parts for our car yet

They have produced a dry carbon hood for our car, per the website, but no info on weight and it is just an OEM hood so no extra venting.

I'm not looking for lexan or plexiglas windows. This is a daily driver. There are some after market glass windows that are actually lighter weight than some stock windshields. Old Porsche trick.

And I'm looking for more esoteric weight reduction opportunities for a street prepared class autocross car. I know how to strip a race car down. Here is my old 2000 lb Boxster.

Shamu, looks so small without a top, lol

Don't let me get my hands on a rolled 370z roadster! Lol!

I did not get the weights of my stock fenders when I had them off, but just by feel my CF fenders are a lot heavier. The stock fenders look like popped aluminium off of the car, they felt as thin as bubble gum wrapper lol. I will ask the guy who got them off me to weigh them when he gets a chance.

[Isamu]

The hood I have coming out will be lighter...

[Mr&Mrs]

The stock fenders are 8 lbs. each.

thanks for the info! rep'ed

Just got the Relentless brake rotor kit in the mail. On my bathroom scale, they're weighing in at 19 lbs per front and 21 lbs per rear. I'll double-check that when I'm weighing the stock ones that come off.

Minor seat-related updates: First post lists TPH seats as 47lbs. My measurements (w/ the factory seat rails still attached) is 47lbs passenger, and 50.8 lbs driver (more adjustable bits). Also, the Bride GIAS LowMax's I just picked up look like they're 42.2 lbs each fully assembled including the 370Z-specific adjustable (front-back sliding) rails, which is way off of the weight listed on the first post, not sure where that came from.
