cf hoods are pretty cool. i got mine for 300 used off a show car. 1 thing i will tell you is that go for a good name like VIS. they clear coat it and stuff which keeps it looking good. my friend has a veilside cf hood on his 350z. hes pist b/c they didnt' clearcoat it well(or at all?) its turning yellow on parts. mine looks great but i make sure to wax it once in a while. do the security thing. i prolly wouldn't have bought it if i didn't see that a dude wanted to sell it cheap. do the other things first. a good alarm is a must. the hoods are light and only 4 bolts hold them on. i can pick it up with one arm. (my mom could probably do the same) i didn't notice much of a performance gain in terms of weight. i like the way it looks.
um...thats it for my input
hope i helped,
