Beyond performance, it gives the Honda Civic a high-end, race-inspired appearance. True dry carbon fiber offers superior strength-to-weight ratio and heat resistance. However, due to its complex manufacturing process, it comes at a higher price point. Some products labeled as "carbon fiber" are actually carbon-look vinyl wraps over fiberglass or ABS plastic—be sure to verify authenticity when purchasing.

ABS Plastic

Acrylonitrile Butadiene Styrene (ABS) plastic is one of the most popular materials in aftermarket auto parts due to its affordability, ease of molding, and consistent quality. It allows manufacturers to produce intricate spoiler designs that fit precisely on the 2005 Civic’s trunk or hatch.

ABS is lightweight and impact-resistant under normal driving conditions. However, prolonged exposure to UV rays and extreme temperatures can cause fading, warping, or cracking over time. For this reason, many ABS spoilers are primed or painted for added protection. Ideal for budget-friendly upgrades, it strikes a balance between cost and functionality.

Fiberglass

Fiberglass is a rigid composite material composed of glass fibers embedded in resin. It is relatively inexpensive and easy to shape into custom aerodynamic forms, making it a common choice for handcrafted or replica spoilers.

While lightweight and paintable to match any color, fiberglass is more brittle than polyurethane or ABS and can crack upon impact. It also requires careful finishing to prevent moisture absorption, which may lead to delamination in humid environments. Best suited for show cars or mild-use applications, fiberglass offers a cost-effective way to achieve a custom look.

Styrofoam (Expanded Polystyrene)

Styrofoam, or expanded polystyrene (EPS), is rarely used in production spoilers but occasionally appears in prototype modeling or ultra-low-cost replicas. It is extremely lightweight and easy to cut or shape, making it useful for mock-ups or temporary installations.

However, it lacks structural integrity and offers no real aerodynamic benefit. It degrades quickly when exposed to sunlight, moisture, or road vibrations. Styrofoam spoilers are not recommended for actual driving conditions and should be considered novelty items at best.
