Best Carbon Fiber Body Parts for the R35 GT-R (Seibon)

Carbon fiber body parts for the R35 Nissan GT-R are lightweight replacement panels — hoods, doors, fenders, and aero — that swap the factory steel and aluminum bodywork for autoclave-formed carbon composite to cut curb weight, lower the polar moment, and sharpen the look. The R35 leaves the factory heavy: a 2009 GT-R tips the scales at roughly 3,829 lbs, and later Premium and Nismo trims climb past 3,900 lbs. That mass is the single biggest thing standing between a stock GT-R and a track-day weapon, which is why lightweight carbon panels are one of the first upgrades serious owners at our Tampa, FL shop reach for. Below we round up the best Seibon carbon fiber parts for the 2009–2016 R35 GT-R, from a $2,250 bolt-on hood to a full $6,300 dry carbon door set, with honest weights, fitment years, and pricing.

Why Carbon Fiber Matters on a 3,900-lb GT-R

Carbon fiber is roughly five times stronger than steel and about two-thirds lighter for the same panel, and it is meaningfully lighter than aluminum too. On a car as heavy as the R35, shaving weight from the extremities — the hood, front fenders, doors, and rear deck — does more than trim the scale number. Weight pulled from the corners and the top of the car lowers the center of gravity and reduces the polar moment of inertia, so the GT-R changes direction faster and loads its Dunlop or aftermarket tires more evenly through a corner. Front-end weight loss in particular helps the nose turn in and eases the load on the front axle under braking.

Every panel in this guide is made by Seibon, one of the most established carbon fiber body specialists in the aftermarket. Seibon parts use a 2x2 twill weave with a UV-resistant clear coat, and the company backs its panels with a limited manufacturer warranty against defects. The key thing R35 owners need to understand before spending is the difference between standard (wet-layup) carbon and dry carbon — it changes both the weight and the price dramatically.

Dry Carbon vs Standard Carbon: What's the Difference?

Dry carbon is lighter and stiffer than standard carbon because it is made with pre-impregnated (pre-preg) sheets cured under heat and pressure in an autoclave, which squeezes out excess resin. Standard "wet" carbon is hand-laid with resin applied during layup, leaving more resin in the finished part. The practical result: dry carbon panels carry noticeably less resin weight and hold their shape better at high speed, but they cost significantly more because the autoclave process is slower and more labor-intensive. In this roundup, Seibon's "OE-DRY," "DRY," and "GTII Dry" parts are the pre-preg pieces; the OEM-style hood and the VS-style aero are standard carbon. If you are building a street car and want the look plus a real weight drop, standard carbon is the value play. If you are chasing every pound for the track or a full show build, dry carbon earns its premium.

Best Carbon Fiber Hoods for the R35 GT-R

The hood is the best first carbon upgrade for the R35 GT-R because it is a straightforward, reversible bolt-on that transforms the front-end look and trims weight from the highest, most forward point of the car. Seibon offers both a clean OEM-shaped hood and a vented GTII race hood for tracked, high-boost cars.

Seibon OEM-Style Carbon Fiber Hood — Best Overall Value

This is the hood we point most street-driven R35 owners to. It keeps the factory hood line and closed profile, so it looks OEM-plus rather than boy-racer, and it accepts the stock latch and hood props for a genuine bolt-on install. Because it retains the OEM shape, it works with your existing under-hood cooling ducting and is the easiest carbon piece to live with day to day. At $2,250 it is the lowest-cost way onto the carbon ladder for the GT-R.

Seibon GTII Dry Carbon Hood — Best for Track & High Boost

The GTII hood is the pick for GT-Rs that see track time or run more boost. It combines the lower weight of dry pre-preg carbon with functional vents that pull hot air out of the engine bay — a real benefit on the VR38DETT, whose twin turbos and intercooler pump serious heat into the bay during hard use. Extended fitment through 2015 makes it the more flexible hood for later cars. At $4,230 it is a race-oriented piece, and the aggressive vented look is a step louder than the OEM-style panel.

Dry Carbon Fenders & Doors: Maximum Weight Loss

Dry carbon fenders and doors are where the R35 sheds the most weight, because they replace large panels of the factory steel and aluminum body structure with pre-preg composite. These are the halo pieces of a serious lightweight build — and they carry the biggest price tags and the most install considerations.

Seibon OEM Dry Carbon Fiber Fenders — Best Weight-Loss Value

Front fenders are one of the best weight-to-look upgrades on the R35 because they sit far forward and outboard, exactly where reducing mass pays off most for turn-in. Seibon's dry carbon fenders keep the OEM contour, so they mate cleanly to the factory bumper, hood, and door lines while dropping meaningful weight over the front axle. They are a favorite pairing with a carbon hood for a color-matched exposed-weave nose. Because they are dry carbon in the OEM shape, they suit both clean street builds and track cars.

Seibon Dry Carbon Fiber Door Pair — The Halo Upgrade

The factory GT-R doors are heavy assemblies full of steel structure, glass, side-impact beams, and window mechanisms, so replacing them with dry carbon is the single largest weight reduction available in Seibon's R35 catalog — and at $6,300 for the pair, the most expensive. These are race-oriented carbon door shells: you transfer your glass, latches, and hardware over, and they are intended for track and show builds rather than a factory-equivalent daily door. If your build already runs a carbon hood and fenders, the doors are the final step to a true lightweight R35.

Carbon Aero: Spoiler, Front Lip & Side Skirts

Carbon aero pieces sharpen the R35's stance and add visual downforce cues while trimming a little more weight. Seibon's VS-Style line is the popular choice: a rear spoiler ($1,800), a front lip ($1,890), and side skirts ($1,980) that share a cohesive aggressive design so you can build a matched carbon body kit one piece at a time.

Seibon VS-Style Carbon Fiber Rear Spoiler

The VS-Style rear spoiler updates the R35's tail with an exposed-weave carbon profile that pairs naturally with the matching front lip and side skirts. It is the most affordable way to add a carbon exterior accent, and because it replaces the trunk-mounted spoiler it does not require touching the bumper. For a complete look, owners commonly add the VS-Style front lip and side skirts — both shown below — to tie the front, sides, and rear together.

Best Carbon Accent: Mirror Covers

If you want the carbon look without a five-figure spend, carbon fiber mirror covers are the highest-visibility upgrade per dollar. They sit right in your sightline, catch the light, and preview the exposed weave you can build toward later.

How to Choose the Right Carbon Parts for Your R35

Choose R35 GT-R carbon parts by matching the panel to your goal and budget. For a street car that wants the look plus a real weight drop, start with the OEM-style carbon hood, then add dry carbon fenders for a color-matched nose. For a track or high-boost build, prioritize the vented GTII dry hood for heat extraction, then the dry fenders and doors for maximum mass reduction. For a show build, run the full dry carbon exterior — hood, fenders, and the door pair — and finish with the VS-Style aero set. On any budget, carbon mirror covers are the cheapest entry point to the exposed-weave look. Always confirm your exact model year against each part's fitment range before ordering, since several pieces are cut for 2009–2010 or 2009–2011 cars.
