The best Infiniti G37 carbon fiber upgrades trade factory steel and aluminum for lightweight, motorsport-grade panels that sharpen both the look and the balance of Nissan's VQ-powered coupe. For the 2008-2013 G37, Seibon offers exposed 2x2 twill carbon hoods and trunk lids in three distinct styles, each finished with a UV-resistant clear coat and built to bolt to the factory mounting points. Below, the team at NLP Performance in Tampa, FL breaks down the four G37 carbon panels we stock most, what each one weighs and costs, and how to pick the right hood and trunk for your build.
Our Verdict
The Seibon TS-Style Carbon Hood is the best all-around pick for the G37 coupe.
Its vented, heat-extractor design gives the biggest visual transformation, trims weight off the nose, and helps vent underhood heat from the 3.7L VQ37VHR. Want carbon weight savings without changing the factory silhouette? Choose the OEM-style hood. Chasing the most single-panel weight loss? The C-style carbon trunk lid replaces the G37's heavy steel decklid and adds a subtle ducktail.
Shop Our Top Pick →Why Add Carbon Fiber to a 2008-2013 Infiniti G37?
Carbon fiber earns its place on a G37 for two reasons: weight and presence. Carbon composite has a density near 1.5 g/cm³ versus roughly 7.85 g/cm³ for steel, so a carbon panel weighs about 30 to 50 percent less than the equivalent steel part. The G37 coupe left the factory with an aluminum hood but a steel trunk lid, which is why swapping the decklid for carbon frees up the most weight of any single panel. Removing mass high on the chassis and out at the ends also reduces the car's polar moment of inertia, which sharpens turn-in and helps the front-engine, rear-drive coupe rotate.
Just as important for most owners is the look. The G37 coupe (sold 2008-2013 before becoming the Q60) is a clean, curvy design, and a woven carbon hood or ducktail trunk instantly signals a serious build. Seibon panels use a hand-laid 2x2 twill weave over a lightweight core, topped with a glossy UV-protective clear coat that resists the yellowing cheap carbon is known for.

Infiniti G37 Carbon Fiber Parts Compared
Here is how the four Seibon G37 carbon panels stack up on panel type, style and price. All four use the same 2x2 twill carbon and UV clear coat.
| Kit | Panel | Style | Best For | Price |
|---|---|---|---|---|
| TS-Style Hood (Coupe)Top Pick | Hood | Vented / heat-extractor | Aggressive | $1,305.00 |

| TS-Style Hood (Sedan) | Hood | Vented / heat-extractor | Aggressive | $1,305.00 |
TS-Style vs OEM-Style Carbon Hoods: Which Look Wins?
The choice between the TS-style and OEM-style hood comes down to how loud you want your G37 to be. The TS-style hood is the statement piece: its sculpted vents and scoops read as pure motorsport, transform the front end, and help release trapped underhood heat — useful on a naturally aspirated VQ37 that likes to run warm during spirited driving. The OEM-style hood is the understated pick. It mirrors the factory hood shape exactly, so from ten feet away it looks stock, but up close the woven carbon and clear-coat gloss give it away. It is also the most affordable G37 carbon hood we stock, which makes it a smart entry point for a clean, weight-conscious build.
The TS-style hood is also available for the G37 sedan.
Pairing a carbon hood with the C-style carbon trunk lid balances the car end to end, dropping weight from both the nose and the tail. If you are building a cohesive look, matching the exposed weave front and rear is the move our Tampa customers reach for most.
Fitment, Installation & Care Notes
Exposed 2x2 twill weave on the Seibon C-style carbon trunk lid.
All four panels are direct-fit to the 2008-2009 Infiniti G37 using the factory hinges, latch and lock hardware, so a competent DIYer with a helper can swap a hood in an afternoon. A few real-world tips from our shop: always confirm coupe versus sedan fitment before ordering, budget for hood pins if the car sees track time, and re-torque and re-align the panel after the first few drives as it settles. Carbon panels ship with a clear gloss coat, but keeping the car garaged and waxing the carbon once or twice a year will keep the weave from yellowing for years.
What We Like
- + Significant weight savings versus factory steel and aluminum
- + Genuine motorsport look with exposed 2x2 twill weave
- + Direct fit to factory G37 mounting points
- + UV-protective clear coat resists yellowing
- + In stock at NLP Performance with G37-specific part numbers
Things to Consider
- – Carbon costs more than a painted steel replacement panel
- – Track use calls for aftermarket hood pins
- – Clear-coat carbon needs occasional care to stay looking new
Frequently Asked Questions
Does carbon fiber make a real difference on an Infiniti G37?
Yes. A carbon fiber hood or trunk lid removes weight from the highest and farthest points of the G37, which lowers the car's center of gravity and reduces polar inertia at the nose and tail. Carbon panels weigh roughly 30 to 50 percent less than equivalent steel parts; because the G37 coupe's trunk lid is steel from the factory, the C-style carbon trunk delivers the biggest single-panel weight savings, while the carbon hoods trim weight off the front and add a genuine motorsport look.
What is the difference between Seibon TS-style and OEM-style G37 hoods?
The TS-style hood is a vented, sculpted design with heat-extractor-style scoops that give the G37 an aggressive, track-inspired face and help vent underhood heat. The OEM-style hood reproduces the factory hood shape and lines exactly, but in exposed 2x2 twill carbon fiber, for owners who want the weight savings and carbon finish without changing the car's silhouette. Both bolt to the factory hinge and latch locations.
Will these Seibon carbon parts fit my G37 coupe or sedan?
These specific Seibon panels are listed for the 2008-2009 Infiniti G37 in both 2-door (coupe) and 4-door (sedan) body styles, with separate part numbers for each. The G37 coupe front end carried over with few changes through 2013, but you should always confirm your exact model year and body style against the product page before ordering, since the coupe and sedan hoods are not interchangeable.
How much do the Seibon G37 carbon fiber parts weigh and cost?
At NLP Performance, Seibon carbon fiber hoods and trunk lids for the G37 run from about $1,170 to $1,305, with the TS-style hoods at the top of the range and the OEM-style hood the most affordable. Carbon hoods typically shed several pounds versus the factory panel, and the carbon trunk lid saves the most because it replaces a steel piece.
Do I need hood pins with a Seibon carbon fiber hood?
For street driving, Seibon carbon hoods use the factory latch and hinges, so hood pins are optional. For track or high-speed use, most builders add aftermarket hood pins as a safety measure, because a lightweight aftermarket hood can flex at speed. Budget for pins if you plan to run the car on track.
Are Seibon carbon fiber panels UV protected and warrantied?
Seibon finishes its carbon products with a UV-resistant clear gloss coat over a hand-laid 2x2 twill weave, which helps resist yellowing from sun exposure; keeping the panel waxed or garaged extends the finish life further. Seibon backs its carbon products with a limited manufacturer warranty against defects in materials and workmanship. NLP Performance can walk you through fitment and warranty details before you buy.
