I see that there are A Lot of CF parts, and many owners have installed them. I know most people enjoy the cosmetic factor. But has anyone weighed the parts vs the stock piece's ? is there any real weight loss. Ive heard that sometimes wet laid CF parts are actually heavier then aluminum or steel parts any truth to this, Thanks -Rob

 

It could be heavier or weigh the same, depending on how it's made and depends on the part. But for this car and this market, most just buy to enjoy the way it looks, not for weight-saving.

Plus 1 for looks.

I'm sure the cf hood and trunk would weigh less though and the cf side mirror replacements.

 

Dry carbon is functional. (And expensive.) The majority of the carbon fiber you'll see on the G37 is purely aesthetic. If there is weight savings, it is, for the most part, negligible.

 

I love the way carbon fiber looks in some applications. I think that the weight savings is negligible unless used extensively. Then every little bit helps. Especially if the car is being tracked when every ounce becomes important.

I do have concerns about things like carbon fiber hoods. I don't believe they are engineered like the OEM hoods to crumple in an accident. They could cause additional damage and even injury, but I have no conclusive proof of this. There have been other issues with roof caps that weren't properly sealed around the edges and moisture got underneath and rusted out the roof.

So unless you are planning to track your car and want every possible advantage, I would suggest using carbon fiber sparingly and primarily for cosmetic purposes.

 

Yup.. Exactly right!

 

Most of my cf is dry carbon except my headlights and grille. But also like the way it looks.

 

unless u go insane like the LFA does with CF, it is just for looks

 

i have heard there is not much weight difference between the CF hood and stock hood

 

Mainly looks IMO

 

The point of cf isn't just weight savings, its strength. Watch the Koenigsegg crash on Top Gear (UK)... barely any damage despite a fairly high speed bump into the tire wall. If done right, it looks good. Wet cf is just for looks.

 

What is this dry carbon fiber process people speak of?

Unless dry CF is the CF lay-ups with a super high vacuum to pull maximum amounts of resin out. After all the epoxy resin is the main component that adds weight.

From my understanding all CF components are resin impregnated. Which makes them wet.

CF has low compressive strength but high tensile strength. Resin is the binder to increase compressive strength.

Someone chime in, so I don't feel like I'm taking crazy pills.
