Lightweight composite materials have become essential in modern high-performance automotive design. A carbon fiber hood (carbon bonnet) is one of the most effective upgrades for the Toyota Supra platform — whether you drive a GR Supra A90/A91, a MK5, or a JZA80 with a legendary 2JZ engine. Many owners upgrading their hoods also explore broader oglekļa šķiedras automašīnas options to optimize exterior performance.
Unlike many articles that focus only on appearance, this guide provides a complete engineering deep dive, covering:
Structural behavior of CFRP Airflow & heat extraction Fitment for A90/A91 and JZA80 Dry vs wet vs double-sided carbon Venting styles (TS / TSII / TSIII / TV / VS / TR / KB) Safety, hood pins, latch load, and gas strut compatibility Thermal behavior (engine bay temperatures, resin performance) Crash behavior of composite hoods Road-legal compliance Shipping, packaging, maintenance, and FAQ This is the most comprehensive Supra carbon fiber hood guide available — written from a composite engineering perspective.
A Supra carbon fiber hood (also called a carbon bonnet) replaces the OEM steel or aluminum hood with a lightweight carbon fiber reinforced polymer (CFRP) structure. These hoods are widely used in:
Depending on construction method, carbon hoods come in several types (more on manufacturing in our guide to How to Make a Carbon Fiber Hood):
Dry carbon (prepreg + autoclave cured) Wet carbon (resin-infused / vacuum bagged) Double-sided carbon (inside & outside CFRP) Forged carbon (random-fiber aesthetic) Carbon-Kevlar hybrid (impact-resistant)
Each differs in stiffness, heat resistance, weight, and durability.
OEM Supra hoods typically weigh:
| Hood Material | Approx. Weight |
|---|---|
| OEM Steel | 12–14 kg |
| OEM Aluminum | 8–10 kg |
| Wet Carbon | 6–8 kg |
| Sausais ogleklis | 4.5–6.5 kg |
| Double-Sided Dry Carbon | 5–7 kg |
Reducing front-end mass improves:
(For deeper hood-specific cost insights, see How Much Are Carbon Fiber Hoods.)
Lightweight modifications on the front axle yield the highest handling benefits.
The Supra B58 engine produces substantial thermal load, making vented carbon fiber hoods extremely effective.
Benefits include:
High-flow vented styles can reduce under-hood temperatures by 8–18°C depending on airflow speed. For broader exterior upgrade context, explore Oglekļa šķiedras kapuces.
Carbon fiber behaves differently from metal:
For track driving, lightweight vented hoods should use hood pins to prevent uplift at high speed. For street use, properly reinforced latch points ensure safe operation if installed correctly.
Different hood styles vary dramatically in airflow performance, structural behavior, and intended usage. Below is an engineering analysis of each category.
Designed for aggressive cooling and track environments, TS-style features:
Ideal for:
High-boost B58 setups Track days / time attack Hot climate environments
Upgrades over TS-style include:
Suitable for:
Higher horsepower builds Intensive cooling requirements Lightweight track-oriented Supra setups
TSIII-style incorporates:
Recommended for heavily modified Supra builds.
TV-style provides a cleaner daily-usable design while maintaining proper venting.
Funkcijas:
Perfect for daily-driven A90/A91.
VS-style is visually striking and pairs well with:
Cooling is moderate but adequate for non-track usage.
Designed around the 2JZ-GTE thermal layout:
Useful for classic MK4 builds. Good for both restoration and performance projects.
Features aggressive lines with moderate venting. Popular for:
OEM-style hoods mimic the factory shape but offer:
Ideal daily usability.
These represent the highest carbon fiber hood specification:
Used for professional motorsport or high-power street builds. For more specialized non-automotive composites, some buyers explore pielāgota oglekļa šķiedra risinājumus.
Forged carbon features randomly oriented short fibers:
Kevlar fiber improves:
Useful in harsh environments or long-distance driving conditions.
Characteristics:
Engineering notes:
JZA80 uses a different engine bay heat map due to the 2JZ-GTE.
Important considerations:
CFRP is anisotropic, meaning:
Therefore:
At highway or track speeds, aerodynamic lift acts on the hood:
Result: Hood pins are strongly recommended for vented or lightweight hoods.
Engine bay temperatures:
Resin can degrade over time, so the underside should use:
A carbon hood installation is not “bolt-on only.” It includes:
DIY installation risks:
CFRP is brittle, not ductile:
| Materiāls | Failure Mode |
|---|---|
| Tērauds/alumīnijs | Bends, absorbs energy |
| Oglekļa šķiedra | Fractures, delaminates |
Thus:
This is normal composite behavior and not a defect.
Some regions require:
This varies by country.
| Tips | Svars | Stīvums | Trases izmantošana | Izmaksas |
|---|---|---|---|---|
| Sausais ogleklis | ★★★★★ | ★★★★★ | Labākais | Augsts |
| Wet Carbon | ★★★★ | ★★★ | Mērens | Vidēja |
| Double-Sided Dry | ★★★★★ | ★★★★★ | Labākais | Augstākā |
| Carbon-Kevlar | ★★★★ | ★★★★ | Harsh environments | Vidēja |
Gloss finish → deep weave clarity Matte finish → motorsport aesthetic Forged finish → visual impact Colored carbon → decorative builds

Common matching upgrades include:
Together, these create a unified aero package and reduce overall weight. For painting considerations, see Can You Paint Carbon Fiber Hoods.
Owners commonly report:
“The weight reduction is immediately noticeable.” “Vented carbon hoods dramatically reduce heat soak.” “Professional installation is mandatory.” “UV-protected clear coat prevents yellowing over years.”
Forums consistently emphasize hood pins, proper alignment, and shipping insurance.
Is a carbon fiber hood safe for daily driving? Yes — if properly installed and reinforced. Lightweight or vented hoods should use hood pins.
Vai man ir vajadzīgas kapuces tapas? Recommended for all vented or lightweight hoods, especially above 120 km/h.
Can I drive in the rain with a vented hood? Yes. Quality vent designs channel water away from sensitive components.
Will OEM gas struts work with carbon hoods? Only sometimes. Lightweight dry carbon often requires soft-rate struts.
Can a carbon fiber hood be painted? Yes — with proper primer prep and heat-resistant paint systems.
How much does a Supra carbon hood cost? Approximate ranges:
Does a carbon hood improve performance? Yes. Reduced front-end weight improves handling, braking, and responsiveness.
