Yes. Seibon carbon doors are shells only. All window glass, regulators, lock mechanisms, wiring harnesses, mirrors, and speakers must be transferred from your OEM doors.
Is professional installation required?Seibon strongly recommends professional installation for door replacements. Door fitment affects safety systems including door latch integrity, window sealing, and side-impact protection. Have a qualified body shop with carbon fiber experience perform the installation.
Are both doors included?Yes. This product includes both doors as a matched pair. Front door pairs and full four-door sets are listed separately , check the product title.
What is the weight savings over OEM doors?Carbon fiber doors are 40-60% lighter than the comparable OEM steel doors. Exact figures vary by vehicle , GT-R doors, for example, drop from approximately 80 lbs per OEM door to under 35 lbs per carbon door.
What is the difference between the standard and DRY carbon versions?Standard versions use 3K 2x2 twill weave carbon fiber over a fiberglass skeleton with a gloss clear coat finish. DRY versions use pre-impregnated (pre-preg) epoxy resin carbon fiber with no fiberglass backing, resulting in a lighter, stiffer panel with a natural matte carbon surface. DRY carbon is the spec used in professional motorsport.
What is the warranty?Seibon provides a fitment guarantee and a 6-month limited clear coat warranty on gloss products. Under the Magnuson-Moss Warranty Act, installing aftermarket doors does not void your vehicle's factory powertrain warranty.
Will my OEM door jamb weather stripping fit?Seibon doors replicate the OEM door contour and include all OEM clip and seal mounting locations. Factory weather stripping transfers directly in most applications.
Are these street legal?Seibon products are intended for off-highway and motorsport use. Buyers are responsible for compliance with applicable safety and street use regulations in their state.
