Carbon fiber body parts for the Toyota GR Supra (A90) are direct-replacement exterior panels — hoods, doors, trunk lids, roof skins and aero — molded from woven carbon-fiber composite to shed weight and lower the car's center of gravity while adding a factory-grade race look. On the 2020–2026 A90, the deepest, best-fitting catalog belongs to Seibon, and at NLP Performance we stock seven of their most popular panels from $1,080 for the MB-Style rear spoiler up to $5,400 for the flagship TS-Style dry carbon hood. This guide ranks the seven pieces our Tampa, FL customers order most, explains the difference between dry and standard carbon, and shows exactly what fits your Supra.
Our Verdict
The Seibon TS-Style Dry Carbon Fiber Hood ($5,400) is the single best carbon upgrade for the A90 Supra.
An autoclave-cured dry-carbon hood strips the most weight from the highest point on the car, sharpens front-end response, and anchors the whole build. Pair it with the dry-carbon trunk lid and roof for a full lightweight shell, then add MB-Style aero to finish the look.
Shop Our Top Pick →Why Carbon Fiber on the A90 GR Supra?
Carbon fiber cuts weight where it matters most. A woven carbon-fiber composite weighs roughly 1.5 g/cm³ — about 40% less than aluminum (2.7 g/cm³) and nearly five times lighter than steel (7.85 g/cm³) for the same volume — while carrying a higher strength-to-weight ratio than either. On a 3,400 lb sports car like the A90 Supra, replacing steel and aluminum body panels with carbon trims curb weight and, crucially, removes mass from high and outboard points: the hood, roof and trunk. Lowering weight up top drops the center of gravity, which is why enthusiasts feel the car turn in flatter and change direction quicker.
The A90 is Toyota's BMW-co-developed, B58-powered coupe (the 3.0L inline-six makes 382 hp in 2021–2026 form). It responds beautifully to weight loss because the chassis is already stiff and well-balanced. Beyond the numbers, carbon fiber is the visual language of the modern tuner Supra — a gloss twill weave or matte dry-carbon finish signals a serious build the moment the hood comes into view. Every panel in this guide is a bolt-on replacement that uses the factory mounting points and hardware.

Dry Carbon vs Standard Carbon: What Is the Difference?
Dry carbon is autoclave-cured pre-preg carbon fiber, while standard carbon is hand-laid over a fiberglass substrate. Dry-carbon panels — Seibon labels them and they carry a matte finish — use pre-impregnated carbon sheets cured under heat and vacuum pressure, producing the lightest, strongest and most consistent panel with minimal excess resin. Standard Seibon carbon parts are hand-laid, vacuum-bagged, then finished with a glossy UV-protective clear coat over a 2x2 twill weave. Standard carbon is heavier than dry carbon but noticeably lighter than OEM steel, and the deep gloss weave is what most people picture when they think "carbon fiber."
In this guide the hood, trunk lid and roof replacement are all dry carbon (matte finish, maximum weight savings), while the doors, rear diffuser, side skirts and rear spoiler are standard gloss-carbon pieces. Both constructions bolt on the same way; the choice comes down to budget, finish preference and how aggressively you want to chase weight.

1. Seibon TS-Style Dry Carbon Fiber Hood — Best Overall
The Seibon TS-Style dry carbon hood is the highest-impact carbon upgrade you can make to an A90 Supra. Priced at $5,400 (part number seiHD20TYSUP-TS-DRY), it replaces the factory hood with an autoclave-cured dry-carbon panel that saves the most weight from the highest, most forward point on the car — exactly where reducing mass sharpens turn-in and lightens steering feel. The TS-Style keeps an OEM-inspired silhouette with subtle venting cues, so it looks purposeful without going full widebody. The matte dry-carbon weave is a signature look on show and track cars alike.
Key Specifications — TS-Style Hood
What We Like
- + Dry carbon saves maximum weight from the highest point on the car
- + OEM-style fit uses factory hood hinges, latch and prop
- + Subtle, street-friendly styling that still reads race-car
Things to Consider
- – Highest price of any single panel in the range
- – Matte dry-carbon finish is different from a glossy weave — confirm the look you want
2. Seibon Dry Carbon Fiber Trunk Lid
The Seibon dry carbon trunk lid ($3,870, part number seiTL20TYSUP-DRY) is the ideal rear-of-car companion to the TS-Style hood. Because it is also autoclave dry carbon with a matte finish, the front and rear of the car match visually and lose weight symmetrically — important for keeping the A90's neutral balance intact. It ships as a direct OEM-style replacement that reuses the factory latch and struts. If you want a cohesive matte-carbon shell, run this alongside the hood and the dry carbon roof.
3. Seibon A90 Carbon Fiber Doors (Pair)
The Seibon A90 carbon fiber door pair ($3,420, part number seiDD20TYSUP) is the most dramatic weight-loss panel on the list because factory doors are heavy steel assemblies. These are standard hand-laid carbon with a gloss twill weave, sold as a matched left/right pair, and they are aimed at track and show builds where every pound off the car's flanks helps rotation. Door swaps are more involved than a hood or trunk — you transfer glass, regulators, latches and mirrors — so budget shop time or professional installation. The payoff is a serious drop in curb weight and a rolling-sculpture look with the gloss weave catching light down the body side.

4. Seibon Dry Carbon Fiber Roof Replacement
The Seibon dry carbon roof replacement ($2,520, part number seiCR20TYSUP-DRY) delivers the single most effective handling change per dollar because it removes weight from the very top of the car. Lowering roof mass drops the center of gravity more than any other panel, tightening body roll and turn-in. This is an autoclave dry-carbon skin with a matte finish; note that roof replacement is a bonded-panel job best left to an experienced body shop. For A90 owners chasing a lower CG and a full matte-carbon top-side, the roof completes the hood-and-trunk trio.
5. Seibon MB-Style Rear Diffuser
The Seibon MB-Style rear diffuser ($1,485, part number seiRD20TYSUP-MB) is the highest-value visual upgrade in the range. It replaces the plain lower rear valance with an aggressive multi-strake carbon diffuser that frames the exhaust and gives the A90's tail the motorsport look it deserves. As a standard gloss-carbon piece it matches the doors and other MB-Style aero, and it bolts to the factory mounting locations. At under $1,500 it is the easiest way to transform the rear-three-quarter view without touching the hood or roof.
6. Seibon MB-Style Carbon Fiber Side Skirts
The Seibon MB-Style side skirts ($1,287, part number seiSS20TYSUP-MB) visually lower the A90 and tie the front and rear aero together along the rocker line. They are standard gloss-carbon pieces designed to sit flush against the factory rockers using OEM mounting points, and they pair naturally with the MB-Style rear diffuser and spoiler for a coordinated body kit. Side skirts are one of the most affordable ways to add carbon presence and make the car look planted from the side profile.

7. Seibon MB-Style Carbon Fiber Rear Spoiler
The Seibon MB-Style rear spoiler ($1,080, part number seiRS20TYSUP-MB) is the most affordable entry into A90 carbon and the finishing touch on the MB-Style aero family. This gloss-carbon spoiler adds a subtle ducktail profile that cleans up airflow off the decklid and sharpens the Supra's rear signature. At $1,080 it is the easiest first carbon purchase for owners who want the look before committing to a hood or full body panels, and it installs to the trunk using the supplied hardware.
How to Build a Full Carbon A90: Where to Start
Start with the hood, then work outward by impact per dollar. If you are chasing weight and one statement piece, the $5,400 TS-Style dry carbon hood delivers the biggest single change to how the car looks and turns in. From there, the dry carbon trunk lid ($3,870) and dry carbon roof ($2,520) build a matched matte-carbon shell that drops the center of gravity and keeps front-to-rear balance neutral. Owners on a tighter budget can get 80% of the visual drama for a fraction of the cost by starting with the MB-Style aero trio — rear spoiler ($1,080), side skirts ($1,287) and rear diffuser ($1,485) — which together run about $3,852 and transform the car's stance without major body work.
A practical order of operations for most A90 builds: 1) rear spoiler and diffuser for instant curb appeal, 2) side skirts to tie the profile together, 3) the TS-Style hood as the centerpiece, then 4) trunk, roof and doors for the committed lightweight build. Because every panel uses factory mounting points, you can add pieces over time without re-doing earlier work. Not sure what fits your exact trim?

Frequently Asked Questions
Does carbon fiber actually make the GR Supra faster?
Carbon fiber makes the GR Supra quicker mainly by reducing weight, not by adding power. Shedding mass from the hood, roof and trunk lowers the car's center of gravity and cuts curb weight, which improves acceleration, braking and cornering agility. Carbon-fiber composite is roughly 40% lighter than aluminum and up to five times lighter than steel for the same volume, so on a 3,400 lb A90 the handling benefit is real — especially from high-mounted panels like the dry carbon roof.
What is the difference between Seibon dry carbon and standard carbon?
Dry carbon is autoclave-cured pre-preg carbon fiber with a matte finish, while standard carbon is hand-laid over a fiberglass substrate with a glossy clear-coated twill weave. Dry carbon is the lightest and strongest option and is used on Seibon's hood, trunk and roof panels. Standard carbon is heavier than dry carbon but still much lighter than OEM steel, and its deep gloss weave is the classic carbon-fiber look. Seibon's doors, diffuser, side skirts and spoiler are standard gloss carbon.
Will Seibon carbon fiber panels fit my 2020-2026 GR Supra?
Yes. Seibon's A90 catalog is engineered for the 2020-2026 GR Supra body, including Base, Premium, Launch Edition and A91 Edition trims. Because the A90 sheet metal is shared across model years, these panels fit all A90 Supras using the factory mounting points, hinges and hardware. Always confirm your exact panel and trim before ordering — our team verifies fitment on every A90 order at NLP Performance.
How much weight can carbon fiber body parts save on the A90 Supra?
Carbon fiber body panels typically weigh 25-50% less than the factory steel or aluminum parts they replace, with the biggest savings coming from large panels like the doors, hood and trunk. Exact savings vary by panel and construction — dry-carbon parts save more than standard carbon. More important than raw pounds is where the weight comes off: removing mass from the roof, hood and trunk lowers the center of gravity and improves how the car changes direction.
Do Seibon carbon fiber parts need to be painted or clear-coated?
No. Standard Seibon carbon parts arrive finished with a UV-protective clear coat over the gloss twill weave, and dry-carbon parts come in their signature matte finish — both are ready to install out of the box. The clear coat helps protect the resin from sun fading, though many owners still apply ceramic coating or paint protection film for long-term UV defense on daily-driven cars. No additional paint is required for the exposed carbon look.
Are carbon fiber body panels street legal?
Carbon fiber replacement body panels like hoods, trunks, doors and aero are generally street legal because they replace existing body parts and do not alter emissions or lighting. Hoods must retain a functioning latch and safety catch, and any panel must be securely mounted. Rules on hood pins and aero can vary by state, so check your local regulations. All Seibon A90 panels reuse factory mounting hardware, which keeps installation OEM-correct.
