Upgrade the Nissan Z’s chassis rigidity with a purpose-built carbon fiber rear strut brace from Seibon. The SEI model blends race-proven stiffness with street-ready durability, delivering a noticeable upgrade in handling precision without adding unnecessary weight.

• Material and finish: high-strength carbon fiber with a protective clear coat to resist heat, wear, and UV exposure for long-term performance.
• Exact fit for 2023+ Nissan Z: engineered to mount to factory rear strut points, preserving OEM geometry and avoiding fitment guesswork.
• Precise dimensions: 44" length × 9" width × 3" height to evenly brace the rear suspension and reduce chassis flex.
• Weight efficiency: approximately 4.0 pounds, offering a noticeable weight savings over traditional steel braces while maintaining rigidity.
• Performance benefits: enhanced rear-end stability during aggressive cornering, improved steering response, and more consistent tire contact patch.
• Durability in real-world conditions: carbon fiber construction stands up to road debris, heat, and environmental exposure for sustained performance.
• Low-maintenance care: simple wipe-down to keep the weave looking sharp and the finish protected over time.
