Seibon RS0910NS370-NSM NSM-Style Carbon Fiber Rear Spoiler

The Seibon RS0910NS370-NSM is an NSM-style carbon fiber rear spoiler crafted to deliver a race-inspired aerodynamic upgrade with a show-ready finish. Designed to replace a factory rear spoiler or dress up an empty trunk lid, this spoiler combines lightweight construction with aggressive styling for a commanding look straight out of the box.

Seibon builds every component using a wet lay-up, hand-laid carbon fiber process, ensuring a consistent weave pattern throughout the piece. The optimized carbon-to-resin ratio produces a part that is both exceptionally stiff and highly durable — without the weight penalty of OEM alternatives.

Key Features:

• Hand-laid wet carbon fiber construction for superior strength and a uniform weave
• Optimized carbon/resin ratio for maximum stiffness and long-term durability
• Factory-applied glossy clear coat that resists chipping and flaking
• Show-ready finish — no painting required
• Aerodynamically designed to improve downforce and rear-end stability
• Individually inspected before shipping for quality assurance
• NSM styling with a bold, motorsport-inspired profile

Seibon's carbon fiber components are trusted by professional drivers and enthusiasts alike. Each spoiler is rigorously inspected before leaving the facility, backed by Seibon's commitment to quality craftsmanship.
