4SRC Carbon Fibre Door Cards for Nissan GT-R R35

Product Overview

The 4SRC carbon fibre door cards are developed for the Nissan GT-R R35 as a lightweight motorsport-focused interior solution, designed to replace the factory door panels with a simpler and more purposeful construction.

These panels are manufactured using a traditional vacuum carbon fibre process. Due to the nature of this production method, slight weight variation between individual parts is normal. Each panel typically weighs approximately 1.4kg to 1.6kg per side.

For reference, an OEM GT-R R35 door card weighs approximately 5kg per side, meaning our carbon version delivers a significant reduction in weight for customers building a more performance-oriented interior.

Key Features

• Carbon fibre construction
• Approximate weight: 1.4kg to 1.6kg per side
• Significant weight reduction compared to OEM door cards
• Clean, functional layout for motorsport-oriented builds
• Suitable for Nissan GT-R R35 models

Weight Information

Because these door cards are not produced using autoclave-cured prepreg carbon fibre, exact part-to-part weight consistency cannot be controlled to the same degree. As such, minor variation is to be expected, and quoted weights should be treated as an approximate range rather than an exact fixed figure.

Approximate comparison:

• OEM door card: around 5kg per side
• 4SRC carbon door card: around 1.4kg to 1.6kg per side

This represents a substantial reduction in overall interior weight.

Intended Use

This product is developed primarily for motorsport, track-focused, and weight-reduction-oriented applications.

Customers intending to use this product on a road car should carefully consider the practical differences compared to OEM interior panels, including but not limited to:

• Increased cabin noise
• Reduced insulation
• A more stripped and functional interior environment
• The need to plan their own finishing and integration approach

This is not intended to be an OEM-equivalent trim replacement.

Installation Notice

These door cards are supplied for experienced customers, workshops, and builders who understand the requirements of custom interior installation.

Depending on the vehicle setup, installation of items such as:

• interior door pulls
• door release solutions
• switch panels
• window controls
• other related hardware or finishing components

may require custom work, fabrication, or prior installation experience.

4SRC does not provide installation instructions, custom fitting guidance, or bespoke installation solutions for this product.
Customers are expected to assess and manage their own installation requirements before purchase.

Important Notice Before Purchase

Please only purchase this product if you fully understand the nature of a motorsport-style interior component.
