Product Details

The Seibon TL9904BMWE464D-C is a CSL-style carbon fiber trunk lid designed as a direct bolt-on replacement for the factory trunk. Built from premium 3K 2x2 twill weave carbon fiber, this trunk lid delivers a dramatic weight reduction of up to 50% compared to the OEM steel panel — without sacrificing structural rigidity or street presence.

Each trunk lid is hand-crafted by Seibon's experienced production team and engineered with an optimized carbon-to-resin ratio for exceptional stiffness and long-term durability. The consistent weave pattern and glossy clear coat finish make this piece show-ready straight out of the box — no painting required.

Key Features:

  • CSL-Style Design — Aggressive styling inspired by the legendary BMW M3 CSL
  • 3K 2x2 Twill Weave Carbon Fiber — High-grade aerospace-quality raw material
  • Up to 50% Weight Reduction — Significant mass savings over the factory steel trunk lid
  • Gloss Clear Coat Finish — Show-quality appearance, chip and flake resistant
  • 100% Bolt-On Fitment — Accepts all factory hinges, handles, and locks; sedan fitment only
  • Optimized Carbon/Resin Ratio — Maximizes stiffness and structural strength
  • No Painting Required — Arrives ready to install and display
  • Backed by Seibon's 6-Month Clear Coat Limited Warranty and Fitment Guarantee

Seibon recommends replacing factory trunk struts or shocks with units appropriately rated for the reduced weight of a carbon fiber lid. This trunk lid is for sedan (4-door) applications only.

Fast & painless other than filling the bank to be able to spend it.

Great prices, helpful customer service. Ordered 2 by mistake. And they got it cleared up real fast. Saved over $80 off retail. Will be ordering from the, again!!!!! <br>

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Excellent service with the actual stock on hand, shipment was made the next day and a tracking number was provided. I have tried 2 other online supply stores which don't know what they have in stock.
