A simple question: if cars are built with crumple zones, meaning the hood is meant to crumple and absorb energy. What happens when you put a (some say indestructable) carbon fiber hood on your car, if you get in a wreck.
I do not plan on getting in a wreck, no one does. My point is, if the hood of a car is meant to absorb energy and it is replaced with a rigid hood that does not 'crumple' what will happen?
Sorry for making a 'simple' question difficult.

Many unpredicted things can happen...that's why in many states CF hoods are illegal. In some cases it will break in half and simply not absorb any energy so the impact goes farther into the car (hard to explain, basically the car gets smashed more because there's less resistance to crumpling). Another case is that it could become detached and actually go through the windshield, but I've only heard of very few cases where that happened. Basically you're right, less energy is absorbed by the hood so more damage is done to the front of the car generally.
yah, I'm sticking with the stock hood.
I wouldn't make any modifications until the warranty expires because I don't want to void the warranty before it ends.
I can do other mod's (battery relocate) to take away from the weight on the front end.
I don't have a SE R SpecV, yet! I went the the nissan dealership earlier today. They have a SpecV with everything but it's yellow. I don't want yellow, so they are looking to do a dealer swap. The dealership has either $1500 cash back or APR from 1.3%, which I might be able to get.
Thanks for your input.. more input is welcome!

Probably not, but other things might. I've read on this forum that if you change the exhaust and something exhaust related breaks, warranty won't cover it. I am going to wait for the warranty to expire before I do any modifications to it for two reasons. 1, I don't want to void the warranty. 2, By the time the warranty expires I will have the majority of the car paid off, so I can afford to modify it.
Thanks for the feedback..

i guess, but modding is always a risk. if you do everything right the first time stuff usually doesn't break. you can always change back to stock fairly easy with bolt ons.
Back to the subject....If you get into a wreck, its not too often that you need your hood to absorb that much force because you rarely have head on collisions at those kinds of speeds and because hoods are thin and they can't absorb that much energy anyway, they crumple so that they dont slide into the cabin and slice your head off, thats why there are little hooks by the hinges, to hook the hood in case of a collision. now, replace that with a CF HOOD, its gonna do the same thing because #1, carbon fiber are strands apon strands and layers apon layers and will crack and chip, each layer giving some resistance, rather than just a clean break. and #2 some carbon hoods come with a metal brace, which in an accident wil bend, and it being attached to the CF, with not let it break, and provide resistance. dont worry, CF hoods are safe, and hoods never get damaged, unless you can't drive and pile into something goin 70. in most cases, people brake hard before an impact, reducing velocity greatly, and damage is usually light. ive been in 6 accidents and only one need and hood to be replaced, and it wasnt even damaged that much. damn...too much velocity and Force talk, thats what i get for taking AP Physics

Yeah, lots of exotics come with cf parts stock, the difference is the car is designed with the cf parts in mind, and their lack of support vs metal parts. The car is designed and crash tested with those parts on, and it is engineered to withstand a collision with those cf pieces. Our cars are not

sounds like it's gonna look hot. too bad i can't afford one
