Seibon 88-91 Honda CRX OEM Carbon Fiber Trunk/Hatch

Slash Weight Without Losing the OEM Look: 3K Twill Carbon Fiber Trunk for the 1988 through 1991 Honda CRX

The Seibon TL8891HDCRX is an OEM-style carbon fiber trunk lid hand built to replace the factory steel trunk on the 1988, 1989, 1990, and 1991 Honda CRX across all trim levels including the DX, HF, and Si. Seibon uses a professional grade 3K 2X2 twill weave carbon fiber fabric throughout the TL8891HDCRX with an exceptional carbon to resin ratio that produces high stiffness and added strength without the weight of the factory stamped steel panel. The result is a show ready gloss finish trunk that retains the factory roofline silhouette and mounts directly using OEM hardware. A fiberglass skeleton is bonded to the underside for rigidity and carries a matte black enamel finish that keeps the interior surface clean and professional. The TL8891HDCRX is an ideal upgrade for CRX owners building a dedicated track car, autocross competitor, or a show vehicle that demands factory correct lines with maximum visual impact.

Frequently Asked Questions

1. Does the Seibon TL8891HDCRX fit all 1988 through 1991 Honda CRX trim levels?
   Yes. The TL8891HDCRX is engineered to fit the 1988, 1989, 1990, and 1991 Honda CRX across all trim levels including the DX, HF, and Si. All three trim levels share the same trunk opening and hinge mounting points on the ED8 and ED9 chassis.
2. Does the TL8891HDCRX come ready to install or does it need painting?
   The TL8891HDCRX ships with a show ready high gloss clear coat finish that requires no painting for most applications. If you intend to paint it to match your body color, normal pre-paint preparation is required including sanding and primer application just as with any body panel.
3. Can I use my factory trunk struts with the Seibon TL8891HDCRX?
   No. Seibon explicitly advises against reusing factory gas struts or trunk dampers with the TL8891HDCRX. Carbon fiber trunk lids are significantly lighter than the factory steel panel, and factory struts are calibrated for the heavier OEM weight. Using stock struts may prevent the trunk from closing properly and could crack the carbon fiber panel under pressure. Aftermarket struts rated for a lighter lid are required.
4. What hardware does the TL8891HDCRX use?
   The TL8891HDCRX reuses your existing OEM factory hardware. No additional mounting hardware is included because the carbon fiber lid is engineered to accept the same hinges, latches, and mounting points as the factory steel trunk.
5. How much weight does the TL8891HDCRX save compared to the stock trunk?
   Seibon does not publish an exact weight figure for the TL8891HDCRX, but carbon fiber body panels of this type typically save 50 to 70 percent of the weight of an equivalent factory steel panel. The fiberglass skeleton on the underside adds back a small amount of structure but the overall weight reduction is still significant for track and autocross applications.
6. Is professional installation required for the TL8891HDCRX?
   Seibon recommends professional installation for the TL8891HDCRX. Carbon fiber panels require careful alignment during installation to ensure proper gap consistency and to avoid stress cracking from uneven clamping of the hinges and latch. An experienced body shop or installer familiar with carbon fiber components will achieve the best result.
7. Will there be any surface blemishes on the TL8891HDCRX?
   Occasional minor surface blemishes may be present on the TL8891HDCRX as a result of the hand fabrication process. Seibon notes that these blemishes may be removed during normal sanding and pre-paint preparation. The gloss finish panels are inspected before shipping but minor cosmetic variations are inherent to handcrafted carbon fiber construction.
8. Is the Seibon TL8891HDCRX subject to California Prop 65?
   Yes. The TL8891HDCRX carries a California Proposition 65 warning for Styrene and Bisphenol A. See the Prop 65 warning at the bottom of this listing for full details.
9. What is the difference between the OEM style and other Seibon trunk styles for the CRX?
   The OEM style TL8891HDCRX replicates the exact factory trunk profile with no raised ribs, vents, or styling modifications. It is the correct choice for builds requiring a stealth look or factory silhouette while reducing weight. Other Seibon styles may feature raised character lines for a more aggressive appearance.
10. Does the TL8891HDCRX fit both the ED8 and ED9 chassis Honda CRX?
    Yes. The TL8891HDCRX is designed for both the ED8 and ED9 second generation Honda CRX platform produced from 1988 through 1991.

Install Instructions

Open the factory trunk and support the lid safely before beginning removal. Disconnect any trunk light wiring harness or strut connections as applicable to your vehicle. Remove the factory hinge bolts retaining the steel trunk lid and set aside for reuse. Carefully lift the steel trunk lid clear of the vehicle with an assistant to prevent damage to the body. Position the Seibon TL8891HDCRX on the hinge mounting points and hand thread the OEM hardware before final torque. Align the trunk to achieve even panel gaps on all four sides before fully tightening the hinge bolts. Install aftermarket gas struts rated for a lighter carbon fiber panel. Do not reinstall factory gas struts. Adjust the trunk latch striker as needed to achieve a flush close without over compressing the weatherstrip. Professional installation is recommended to ensure correct alignment and to prevent stress cracking.
