At just 4lbs, this is our lightest version of the GTR trunk and intended for the full fledged race cars. Made as a reinforced skin only this trunk requires the use of pins for mounting. This part is made using our high standard, high strength, low weight aerospace grade 12K carbon fiber with a divinycell foam core sandwiched between the carbon to keep the weight at a minimum but still retain enough strength and stiffness to to handle the high amounts of aero loading and downforce these cars are capable of producing while eliminating the skeleton. This part like all our others is infused with a UV stable epoxy resin to prevent any Yellowing or sun damage over the years, however it is still advised to either clear coat them or wrap them for protection from weather, chemicals and added UV protection. Because this part is intended for race vehicles it is offered standard without a clear coat for the lowest weight option for those who will be wrapping the cars with a race livery, but there is still an option to have them cleared if wrapping is not desired.
