our trunk and hood is already really light, i don't think it saves that much weight. CF hood on today's car is like pretty mod. so if you like the look, yes its good, but i don't think its wroth it

i know of a company that can make any custom cf product you like. if you guys are interested, let me know and i will find out on pricing. i do believe it will be cheaper than 600-800 bucks.

Do you GD guys get an aluminum trunk or something?
The GC has a heavy trunk, I suspect steel, CF would definitely help a lot.
It is true that CF vs Al, Al is close enough in weight that it usually isn't worth it, because race-grade carbon parts are so expensive.
But oh baby, that would look fine!

It only looks subtle and euro style if you paint over it
and even then you could just mold an STi limited spoiler to your existing trunk and paint it for much less
Is the trunklid a part of the crash structure? It would probably take a lot of the impact if you got hit by a higher vehicle such as an SUV or raised truck. maybe a bad idea for safety reasons (CF is strong but unlike steel it can shatter and often aftermarket CF parts are not nearly as strong as OE quality products).

go unbolt your trunk or take out the torsion bars and tell me if you still think its light. I have a regular WRX winged trunk with no torsion bars on my car and a cf trunk waiting for something to cover its wing holes sitting in my garage, and trust me, theres a difference

May of last year I was rear ended in my subie. I was stopped at a light and a lady going 55 mph hit me from behind with no warning (bmw x5 @ 6500lbs.). This lady never hit her brakes. No skid marks nothing. My car took the full hit, my carbon trunk took 80%. During the hit, My drivers seat broke in two areas, at the recliner and at the head rest. I woke up staring at the ceiling of my car. I still have major back problems, pinched vert in two parts of my back and one in my neck and lost of vision in one eye.
When we looked at the car, We saw that the carbon trunk bowed in 7-9 inches before the trunk latch broke. As you can see by the picture it pulled the latch in really far. Thinking on how carbon fiber works. That trunk absorbed alot of energy.
Crazy enough to think it also snapped back into shape and did not explode into bits and pieces. Matter a fact I still have the trunk on my car. I have a new one and spoiler in my garage.
The damage to my car was both 1/4 pannels, trunk floor, tail lights, tail light pannel, bumper and so on.

When we all looked back at if there was the oem trunk installed. I and others bet (including my lawyer) I'd be worse off today. As the oem trunk would have transfered more impact to the rest of the car then onto me.
Carbon fiber is a great impact structure, That why its used in aircraft, F1 racing and so on.
So the whole carbon is bad for accidents is b.s.

B.T.W. My carbon trunk lid and carbon STi spolier is less weight then a oem plain jane wrx truck lid.
Also the carbon STi wing doesnt flap in the wind like the oem ones do.

Did anyone see the fiberimages video, where they run over their hood with a truck?
here's that: http://www.fiberimages.com/videos/Video1.wmv
One of the possible concerns with race grade CF hoods, was that, in a bad front end accident, they would actually snap the hood mounts, and shoot back into the passenger compartment. Anyone hear of this actually happening?
Carbon guillotine?
I do not think a CF trunk would have that issue

i could see something like a carbon hood saying in shape and possibly snapping latches and mounts as far as coming for the driver best bet it would have is coming through the windshield.
06STi damn that sux sorry to hear about that... crazy how it held up to all of that.
