Seibon Part Number (SKU): RL23TYGRCOR-MB
The Seibon MB-style carbon fiber rear lip for the Toyota GR Corolla is designed to enhance rear-end styling, add subtle aerodynamic presence, and introduce a lightweight carbon fiber accent to the factory rear bumper.
Rear lips refine the visual balance of the vehicle by extending and reshaping the lower bumper profile. On the GR Corolla, the MB-style rear lip adds a more aggressive and motorsport-inspired look while maintaining clean OEM-style integration. Constructed from premium carbon fiber materials, this component combines visual impact with lightweight performance design.
Sold as a pair and engineered specifically for the GR Corolla platform, the Seibon rear lip is ideal for enthusiasts looking to elevate the rear styling of their vehicle with authentic carbon fiber construction.
Upgrading to a carbon fiber rear lip provides both aesthetic and functional advantages:
Enhanced rear bumper styling with a motorsport-inspired design
Lightweight carbon fiber construction
Improved visual balance with front lips and side skirts
Premium exterior carbon fiber finish
OEM-style fitment and integration
While primarily a visual upgrade, rear lips also contribute to aerodynamic styling by subtly shaping airflow around the rear bumper area.
The Seibon GR Corolla rear lip is manufactured using advanced carbon fiber production techniques to achieve optimal strength, weight reduction, and visual quality.
Key construction features:
High-quality 3K 2×2 twill weave carbon fiber
Optimized carbon-to-resin ratio for stiffness and durability
Consistent weave pattern and hand-crafted construction
Lightweight composite structure compared to factory materials
Sold as a pair for balanced rear bumper styling
Seibon’s manufacturing process focuses on creating performance-oriented carbon fiber components that reduce weight without sacrificing structural integrity or finish quality.
