carbon fiber hood vs carbon fiber trunk which saves more weight?
 

which saves more weight compare to their stock counterparts? please chime in.

Don't know about trunk but IIRC a carbon hood is heavier than stock.

MPH fabrications is lighter than stock, but you are right the Seibon ones are super heavy.

Save-on shit is garbage. I would never let their replica bullshit touch my car

wow, glad i posted this, almost pulled the trigger on the Seibon CF hood lol

People that spend money on carbon hoods for "weight savings" need better imaginations.

Just remove the hood? Maximizes weight savings.

There are many ways to cut weight. But, Replacing the aluminum hood is not the mod you are looking for.

Get a lightweight battery. It's the best savings of weight to dollars.

just make sure you get a trickle charger and have a place to plug it in if you do not drive your car every day.

Getting a real carbon hood is probably one of the last weight savings mods you should do, both because of the price and the fact that it won't save that much weight.

Taking out everything behind the front seats saves a ton more weight. start here for real weight savings ideas.

None of them saves too much. The hood is already aluminum and about the trunk it is good to have some more weight on the rear cause of better weight distribution. It doesn't really worth it, unless your car has already stripped interior, a rear wing for down force and you want to save the last possible grams. The only thing that might worth it is to go for carbon fiber doors, but I suppose you won't have the same protection in side collisions. Such changes should be really done on a dedicated racing car that will go with a trailer from-to the track.

Given that stock aluminium hood is rather light, sometimes lighter then some of aftermarket options, and you already have it ..
The weight winner is ... stock hood & money spent on other then hood lighter parts :D

Does not apply to all cars but the best weight savings is the steering wheel actuator weight reduction. Dependent on the car it can be 1 to 100lbs+ in weight savings. For some reason this applies more to US vehicles?

The trunk iirc saves a decent amount of weight. @MisterSheep got actual weight measurements... Perhaps he could provide some insight

Please identify what cars have a 100 pound steering wheel actuator? I am truly curious.
I highly doubt that many even reach half a pound.


Edit: Never mind. The guys clued me in on my foolish misread!

Verus makes a ECU and fuel rail bracket cover that saves 5 pounds. Probably more than a cf hood would at 1/8th the price

It's 100lbsPLUS! Get it right!

My car's steering wheel actuator is just under 150 pounds, but if I did some weight reduction of anywhere near 100 pounds, it would no longer be functional. I can however see some that may be able to cut down that much weight, but i have a hard time imagining one of that size inside a twin :iono:

sir, I dare say that you do not weigh half a pound.

Ahhhh I get it now! My confusion came from the fact there actually IS a steering actuator!


I am just a bit dense.

LOL

I legit thought you guys were talking about the power steering actuator [emoji38]

So did I which was why I was baffled.

You'd probably only see weight savings with dry carbon fiber hoods, such as the one from Amuse... but that costs $5k. Seibon has one too for close to $2k. Weight savings is roughly 5lbs from stock.

Wet carbon trunks generally do save more weight relative to a wet carbon hood... which like many others have stated weigh more.

The steering wheel actuator reduction does not work as good as the 170lb passenger delete mod!

When I weighed mine the carbon trunk was 6lbs

Stock trunk 5lbs.

:popcorn:

My stock trunk with Sard wing and oem carpet was 22lbs

So do you pro solo or something?

You want to save weight? Go on a diet and drive around with less gas in the tank. And drain the windshield washer fluid.
Costs nothing.

Yeah, I could shave 40-50 pounds off the nut behind the wheel and it would make a noticeable difference.

So If you move the carpet and wing to the CF one it would still weigh one lb more.

and is asinine and useless. Anthony finally weighed his car and it came in at 2280 lbs, which is not much more than a Yaris, and a hell of a lot less than stock. If you don't think that would totally change the car then you are nuts.

go on a diet. you will lose more weight when driving your car compared to a cf hood or trunk.

Following are the weights of the first cars in Japan. There was a trim level called RA (Race Altered or by SoA Record Attempt) which weighted 1190kg (2623 lbs). This weight was without an A/C and with a ligher factory battery. With an A/C and the normal battery the weight was about 1202 kg. These two gave an almost 6kg/PS ratio and without any carbon parts. ;)

Never understood carbon panels on street cars. looks dumb, and after a few years, looks like shit with highly visible swirls or peeling clear coat.

If you're rolling on stock wheels, get lighter wheels from a quality company. It'll be much more beneficial than getting carbon hoods or trunks and has less tendency to age poorly if you go with a tasteful wheel design.

I weighed the stock hood vs. a Seibon carbon fiber hood. The Seibon VS style hood is lighter by 3.6 pounds. Other CF hoods and designs might be heavier but that particular hood is lighter.
OEM hood weight = 16.4 pounds
Seibon VS style hood weight = 12.8 pounds

My friend held onto each hood while standing on a scale then we subtracted his weight.

Sorry to revive an old thread.

Carbon fiber roof is 10lbs which is more weight saved than your average carbon trunk and hood combined.

Does anyone make a carbon replacement roof? All I've seen are the pointless dress-up panels that go over the stock roof. Not saying I'm going through the hassle of replacing the roof, but it'd be interesting to know the parts exist.

collecting dust

That's more affordable than I would have expected.
