they may not, but they dont charge $870 for theirs either! you need to post pics- its smart business, esp if its the most expensive one out there. for the record- the other compay DID post pics of their fiberglass bottom.VividRacing.com said:I don't have any pics of the underside of the hood. Looks pretty much like the stock one with out the sound deading material, and it's black. Don't see may carbon hood manufacturs releasing pics of the under side unless the hood is full carbon top and bottom. THe Kaminari is fiberglass on the underside. The vent is fully functional like the stock vent though the Kaminari has a larger scoop. The wieght is lighter than stock though no acctually wieghts are offered.
