4SRC Type 3 Prepreg Carbon Ducktail Boot Lid (Trunk) for Nissan GT-R R35 (2007–2024)

Key Highlights

• Prepreg carbon fibre with autoclave construction
• Integrated ducktail design with OEM spoiler compatibility
• Supplied without pre-drilled spoiler holes for flexible setup
• Approximate weight: 3kg

Product Overview

The 4SRC Type 3 Ducktail Boot Lid is developed for the Nissan GT-R R35 platform, combining lightweight prepreg carbon construction with a functional aerodynamic design.

Unlike conventional designs that prioritise either styling or compatibility, this boot lid integrates a subtle ducktail profile while retaining OEM spoiler mounting geometry, allowing greater flexibility in rear-end configuration.

This design approach has been part of our production since 2020, developed with both aerodynamic function and real-world usability in mind.

Construction

Manufactured using pre-impregnated (prepreg) carbon fibre and autoclave curing, this boot lid offers a high level of structural consistency, surface quality, and weight reduction.

The result is a lightweight panel designed for performance-oriented applications while maintaining proper fitment and mounting integrity.

• 2x2 carbon weave finish
• Autoclave-cured prepreg construction
• Approximate weight: 3kg

Aerodynamic Design Approach

The integrated ducktail profile creates a more defined trailing edge for airflow separation at the rear of the vehicle.

Compared to a flat deck surface, this design helps stabilise airflow as it exits the body, contributing to improved aerodynamic balance at higher speeds while maintaining a clean and understated appearance.

This approach reflects a broader shift towards functional rear-end aero design, where subtle geometry changes provide measurable benefits without excessive visual impact.

Flexible Configuration

The 4SRC Type 3 boot lid is designed to support multiple build configurations:

CLEAN CONFIGURATION

Supplied without pre-drilled spoiler mounting holes, allowing a clean rear profile.
Suitable for drag-oriented builds or customers seeking a minimal OEM+ appearance.

OEM SPOILER CONFIGURATION

Retains compatibility with OEM rear spoiler mounting positions, allowing direct installation while benefiting from the integrated ducktail design.

EXTENDED AERO CONFIGURATION

Compatible with 4SRC add-on carbon spoiler extensions mounted onto the OEM spoiler, providing an additional layer of aerodynamic enhancement.

This flexibility allows the same component to suit both clean builds and more performance-focused configurations.

Weight & Performance

With an approximate weight of 3kg, this boot lid offers a meaningful reduction compared to the factory aluminium panel.

Reducing weight at the rear of the vehicle contributes to improved overall balance and responsiveness, particularly in performance-oriented driving conditions.

OEM Integration

Designed as a direct replacement for the factory boot lid:

• OEM latch position retained
• OEM gas strut mounting retained
• OEM mounting alignment maintained

This ensures proper installation and consistent panel fitment without modification to the vehicle structure.

Spoiler Compatibility

This boot lid is compatible with:

• OEM rear spoiler
• OEM-style aftermarket spoilers
• 4SRC add-on spoiler systems

The product is supplied without pre-drilled mounting holes to allow flexibility depending on the intended setup.

Nismo Spoiler Compatibility

Nismo rear spoiler systems are not compatible with this boot lid.

Due to differences in mounting design, Nismo spoiler assemblies extend across and engage with the rear edge of the factory boot lid.
The integrated ducktail profile alters this geometry and prevents correct installation.

Customers intending to use Nismo spoiler setups should retain the OEM-style boot lid.

Aftermarket Wing Applications

Larger aftermarket wing setups introduce significantly higher aerodynamic loads compared to OEM-style spoilers.

For such applications, appropriate reinforcement and installation methods are required to ensure proper load distribution.

Due to variations in wing design and mounting configuration, we recommend contacting us directly prior to installation. Our team can advise based on your specific setup.

For dedicated motorsport applications, chassis-mounted wing systems remain the preferred solution.

Improper installation or load application may lead to structural stress or long-term damage.
