Description

The Seibon carbon fiber rear seat delete for the Toyota GR Corolla is designed to reduce interior weight, create a cleaner motorsport-inspired cabin layout, and add a premium carbon fiber finish to the rear interior.

Rear seat delete panels are commonly used in performance-oriented builds to remove unnecessary weight and simplify the interior while maintaining a high-end appearance. On the GR Corolla, this upgrade replaces the factory rear seating area with a lightweight carbon fiber panel, improving the vehicle’s performance-focused character without sacrificing visual quality.

Available in both gloss and matte carbon fiber finishes, this rear seat delete allows you to tailor the look of your interior to match your build style.

Finish Options

This product is available in two carbon fiber finishes:

• Gloss Carbon Fiber

  • Seibon SKU: RSD23TYGRCOR

  • High-gloss clear-coated carbon fiber finish

  • Ideal for show-focused builds and exterior carbon fiber matching

• Matte Carbon Fiber

  • Seibon SKU: RSD23TYGRCOR-MF

  • Satin/matte carbon fiber finish

  • Ideal for track-inspired or stealth interior builds

Both versions use the same carbon fiber construction and mounting design. The difference is purely visual.

Key Benefits of a Rear Seat Delete Upgrade

Installing a rear seat delete in the GR Corolla provides both performance and aesthetic advantages:

• Reduced overall vehicle weight

• Improved power-to-weight ratio

• Cleaner, motorsport-inspired interior layout

• Additional usable rear cargo space

• Premium carbon fiber appearance

While exact weight savings vary depending on removed components, replacing factory rear seating with a carbon fiber panel can meaningfully reduce rear-end mass and contribute to a more performance-focused setup.

Performance vs Practical Benefits

The Seibon rear seat delete provides a unique balance of performance and usability.

From a performance perspective, reducing rear interior weight can improve handling balance and responsiveness.

This makes it suitable for builds focused on track performance, visual customization, or both.
