Our Verdict
For most R35 GT-R owners, the Seibon GTII Dry Carbon Hood is the smartest first carbon buy — it drops the most nose weight, adds functional engine-bay venting, and shows real two-sided dry carbon weave.
Dry carbon panels cost more up front but run roughly 30–40% lighter than standard wet-layup carbon and finish clean on both sides. If budget is the priority, the standard GTII-Style hood delivers the same shape for far less. Below we compare Seibon’s dry and standard hoods, doors, and fenders for the 2009–2021 R35.
Shop Our Top Pick →Choosing R35 GT-R carbon fiber body panels comes down to one fork in the road: dry carbon or standard carbon. Both shave weight off Nissan’s 3,800–3,900 lb twin-turbo icon, both bolt to the same VR38DETT-powered chassis, and both wear the same 2x2 twill you want people to notice at a meet. The difference is how they’re built, how much they weigh, how they look up close, and how much they cost. At NLP Performance in Tampa, FL, GT-R owners ask us this exact question every week, so we lined up Seibon’s dry and standard panels for the 2009–2021 R35 and broke down which one earns your money.
What Is the Difference Between Dry and Standard Carbon Fiber?
Dry carbon is autoclave-cured pre-preg carbon fiber with the weave exposed on both sides, while standard (“wet-layup” or OEM-style) carbon is hand-laid over a fiberglass backing with only the top face showing. That single manufacturing difference drives everything a buyer cares about: weight, finish, stiffness, and price. Dry carbon uses resin-impregnated sheets vacuum-bagged and baked under heat and pressure, which squeezes out excess resin and yields a panel that is typically 30–40% lighter than the same part made with a wet layup.
Standard carbon — what Seibon labels “OEM-style” — is still a genuine carbon-fiber panel and still far lighter than the R35’s factory steel and aluminum body parts. It just carries a fiberglass reinforcement layer on the underside and a hand-applied clear gel coat, so it weighs more than dry carbon and shows the weave on one side only. For a painted panel it makes no visible difference; for an exposed-weave look, dry carbon is the premium choice because both faces are finished.
Dry carbon shows a clean, uniform 2x2 twill on both faces — no fiberglass backing.

The Panels We’d Put on an R35 GT-R
Below are the individual panels with pricing, part numbers, and fitment. Prices shown update live from our catalog; in running text we quote approximate ranges because promotions change. Each Seibon part ships with a limited manufacturer warranty against defects — always test-fit before paint.
1. Seibon GTII Dry Carbon Hood — Best Overall
The GTII hood is the panel most R35 owners buy first, and the dry-carbon version is our top pick because it stacks the two biggest benefits: the largest weight cut over the factory aluminum hood, plus twin functional vents that pull heat off the VR38DETT’s turbos in stop-and-go and track use. Around the $4,200 mark it isn’t cheap, but the two-sided weave means it looks finished from any angle with just clear coat. It fits 2009–2015 R35 models including Base, Premium, Black Edition, Nismo, and Track Edition.
Key Specifications
2. Seibon Dry Carbon Doors (Pair) — Biggest Statement
Carbon doors are the halo upgrade for a serious R35 build. At roughly $6,300 this dry-carbon pair is the most expensive panel in our lineup, and it earns the price by swapping two of the heaviest hang-on body parts on the car for full two-sided carbon. It’s the most demanding install here — you transfer glass, regulators, latches, and wiring — so we recommend professional fitment. Fitment spans 2009–2020 R35 including 50th Anniversary, Black Edition, Nismo, Premium, Pure, and Track Edition.
Standard OEM-style carbon doors save cost while keeping the factory shape and glass.
3. Seibon OEM-Style Carbon Doors (Pair) — Value Doors
Want carbon doors without the dry-carbon premium? The OEM-style pair keeps the identical factory shape and glass hardware but uses a standard wet-layup construction with a fiberglass backing, which is why it lands near $4,320 instead of $6,300. If you plan to paint your doors body color anyway, the single-sided weave is a non-issue and you pocket the difference. It shares the same broad 2009–2020 R35 fitment as the dry-carbon set.
4. Seibon OEM Dry Carbon Fenders — Lightest Front Corners
Fenders are the subtle-but-smart carbon buy. Because they trim weight at the far front corners of the car, ahead of the front axle, dropping mass there sharpens turn-in more than the raw ~10 lb figure suggests. These are OEM-shape dry-carbon panels near $3,780 that keep the R35’s stock lines while adding a factory-plus carbon accent. Note the tighter 2009–2010 fitment window, so confirm your model year before ordering.
5. Seibon GTII-Style Carbon Hood — Best Value Hood
This is the same aggressive GTII vented shape as our top pick, but in standard carbon at roughly $2,700 — about $1,500 less than the dry version. You still get the functional hood vents and a real carbon top face; you give up the two-sided weave and a few pounds. For a hood you intend to paint, or for a first-time carbon buyer testing the look, it is the best value in the R35 lineup.
How Much Weight Does Carbon Fiber Save on a GT-R?
A typical carbon-fiber body panel saves an R35 GT-R roughly 8–20 lb per part versus the factory steel or aluminum piece, with dry carbon at the top of that range. Carbon fiber has a density near 1.5 g/cm³ against roughly 7.85 g/cm³ for steel, so even accounting for the resin and panel thickness needed for stiffness, a finished carbon panel weighs a fraction of a stamped-steel equivalent. The R35 already uses an aluminum hood, doors, and trunk from the factory, so real-world savings on those parts are smaller than on an all-steel car — but the panels also sit high and at the corners of the chassis, where removing mass helps handling out of proportion to the number on the scale.
Stacking a hood, both fenders, and both doors in dry carbon can pull a meaningful chunk off a car that leaves the showroom around 3,900 lb. Just as important for a 480–600 hp twin-turbo, the GTII vented hood helps evacuate under-hood heat, which is why it’s the panel we recommend first for owners who see track days or Florida summer traffic.
Dry Carbon vs Standard: Which Should You Buy?
Buy dry carbon if you want the lightest panel and an exposed two-sided weave you’ll clear-coat and show off. Buy standard carbon if you’re painting the panel body color or want the carbon look for the lowest price. Here’s the trade-off at a glance.
Dry Carbon — What We Like
- + Lightest option — roughly 30–40% lighter than wet layup
- + Two-sided exposed twill looks finished with just clear coat
- + Autoclave pre-preg construction is stiff and consistent
Dry Carbon — Things to Consider
- – Highest price — often 40–60% more than standard carbon
- – No cost benefit if you plan to paint the panel body color
Standard Carbon — What We Like
- + Much lower price for the same shape and top-face weave
- + Still far lighter than factory steel-bodied panels
- + Ideal when the panel will be painted body color
Standard Carbon — Things to Consider
- – Heavier than dry carbon due to the fiberglass backing
- – Weave shows on one side only — underside is not finished
Fitment, Finish & Installation Notes
Every panel here is model-specific to the R35 GT-R, but the fitment windows differ — the doors cover 2009–2020, both GTII hoods cover 2009–2015, and the dry fenders are listed for 2009–2010, so match the part to your exact year before checkout. Carbon-fiber body panels ship unpainted and require UV-protective clear coat or body paint; leaving raw carbon exposed to Florida sun without a proper clear will yellow the resin over time.
We always test-fit before any paint or clear goes on, because aftermarket panels can need minor gap adjustment, and Seibon’s limited warranty covers manufacturing defects, not panels already finished or installed. Hoods should use hood pins or the factory latch verified for secure closure at speed. If you’re pairing carbon with other R35 work, see our companion guides on carbon door options and browse the full exterior styling collection for lips, spoilers, and diffusers that match the same weave.
The GTII hood’s twin vents help evacuate heat from the VR38DETT’s twin turbos.
Frequently Asked Questions
What is the difference between dry carbon and standard carbon fiber?
Dry carbon is autoclave-cured pre-preg carbon with the weave exposed on both sides, while standard (wet-layup) carbon is hand-laid over a fiberglass backing with the weave on the top face only. Dry carbon is typically 30–40% lighter and costs more; standard carbon is cheaper and still much lighter than factory steel or aluminum panels.
Does a Seibon carbon fiber hood fit the R35 GT-R without modification?
Seibon’s GTII hoods are made specifically for the 2009–2015 Nissan GT-R (R35) and are designed as direct-fit panels, but aftermarket carbon parts should always be test-fit before painting. Minor panel-gap adjustment is normal, and hoods should be secured with a verified factory latch or hood pins for safe high-speed closure.
How much weight does carbon fiber save on a Nissan GT-R?
Expect roughly 8–20 lb saved per carbon body panel versus the factory piece, with dry carbon at the top of that range. Savings are smaller on the R35 than on all-steel cars because the GT-R already uses aluminum for its hood, doors, and trunk, but the panels remove mass high and at the corners of the chassis where it most benefits handling.
Are Seibon carbon fiber panels worth it for the R35 GT-R?
For owners chasing weight reduction and a genuine carbon look, yes — Seibon is one of the most established carbon body specialists, and its R35 panels range from about $2,700 for a standard vented hood to $6,300 for dry-carbon doors. Choose dry carbon for exposed-weave builds and standard carbon if you plan to paint the panel body color.
Do carbon fiber body panels come pre-painted or need finishing?
They ship unpainted and require finishing. Every panel needs either a UV-protective clear coat to preserve the exposed weave or full body-color paint. Raw carbon left exposed to sunlight without clear will yellow over time, so plan for professional clear or paint as part of the install budget.
Which R35 GT-R carbon fiber part should I buy first?
Start with a vented GTII hood. It delivers the biggest single-panel weight cut over the factory aluminum hood and adds functional engine-bay venting for the VR38DETT’s turbos. The dry-carbon GTII hood is our top pick around $4,230; the standard GTII hood offers the same shape near $2,700 if you plan to paint it.
