This is our highest end and by far the strongest version of the GTR trunk available anywhere. the GTspec adds a full layer of divinycell foam core and an extra layer carbon to the top section of the standard skin layer of our performance spec trunk, along with a full carbon skeleton underneath for an insanely strong trunk that still only weighs 7lbs (30% less than the stock aluminum trunk). If you plan on running a larger GT trunk mounted race wing this is the trunk you want! Like the rest of our parts these are made with a high strength low weight aerospace grade 12K carbon fiber infused with a UV stable epoxy resin before being clear coated for added protection from UV rays and weather before being shipped out. These are hand made to order and typically take 3-4 weeks from order to ship out. Since they are made to order they can also be made using any other weave pattern available to match your other parts or theme for an additional fabric charge, contact us for details.
