carbon fiber hood

Are you sure you got JSP? Many companies are no longer using double sided carbon any more cause of the shortage on Carbon Fiber.
I have ordered several JSP hoods in the past if you need help identifing its a true hood or not
Thanks

You know I'm partial to del sols though..

i got mine off ebay for $300 shipped for my ej8 and it fits like a glove. so i think you got jipped
mine also weighs SOOO much less than stock, we could feel the weight taking the stock one off, but the CF one was so light we almost got it airborne picking it up because we expected it to weigh more

carbon fiber is fun and all, but I personally think it is crap. For anyone who has worked with carbon fiber it is only strong in one direction, and that direction my friend is not the direction you are traveling in. You get in one accident and expect to have carbon fiber pieces explode in your face. The more carbon fiber you put on your car the less protection you get in an accident. Just my .02 cents.

While it is true that cheap carbon (cosmetic parts, most of the stuff on the market) parts don't have the impact absorbtion of a big heavy piece of steel, you're grossly oversimplifying carbon as a structural material. How much protectection do you think stock steel fenders add? I'll give you a hint: practically nothing, they're mostly cosmetic. So what about the aluminum hoods, are they inherently unsafe also? Just because they don't weight as much as steel, does that mean they aren't capable of performing as well or better than a cheap steel part? Notice I said cheap, because I want to stress that steel is used mostly because of cost and easy of manufacturing, as opposed to it's physical properties. High end cars (some Audis, etc) use alum because you can get the same properties, less weight, but at a higher cost. There's that cost word again.
For sake of discussion, what do most single seater (open wheel), prototype (LMP1/P1, etc), motocycles, and many exotic cars use exclusively for their impact attenuation and dissipation structures? The correct answer would be carbon. Chassis tubs, nosecones, etc., are all careful made to that they will outperform a much heavier, much less consistant steel part. Carbon has the advantage of absorbing a lot of energy in a few different failure modes, and is used for a lot of military armor uses also. It also has one really interesting property, which goes full circle to your statement. The strength in a carbon composite (or any composite for that matter) lies in the direction that the fiber is oriented. This can be totally tailored to the application, from as simple as using a carbon cloth to as complex as a asymmetrical unidirectional part, or a filament wound part like a carbon driveshaft or hydraulic accumulator. As soon as the fibers orient in anything other than a parallel line, you've just added strength in another direction. So a woven carbon fabric (hey wait, isn't that what carbon hoods are made out of) has strength in at least 2 directions if the fibers are at angles to each other. Then add in something with other complimentary impact attenuation properties, like Kevlar/Aramid fiber, and you've got quite a high performance part. Carbon has a much higher tensile strength per weight than steel, there isn't any way around that.
So your statement only applies to cheap carbon hoods that are purely cosmetic, because proper composite hoods can easily equal steel for impact protection. You're not going to get them for $500 though..
Your turn.
