Do I need hood pins for this carbon fiber hood?

Yes. Hood pins are required for this panel. Carbon fiber hoods benefit from pin support at high speeds to prevent lifting. Source a pin kit separately and install them into the existing latch and hinge locations on your frame.

Will carbon fiber absorb moisture or degrade in the rain?

No. Carbon fiber itself is inert and will not absorb water. A clear coat applied after final prep will seal the weave and protect against UV exposure and road chemicals. Sand and prep the surface before applying your chosen clear coat finish.

How does the weight compare to the factory hood?

Carbon fiber is significantly lighter than OEM steel, which reduces unsprung mass at the front and improves handling balance. The exact weight savings depends on thickness and layup, but carbon is the weight-optimized choice for this application.
