How to Choose a 1999 Honda Civic Body Kit: Fitment & Options

🔧 If you're searching for a 1999 Honda Civic body kit, you're likely looking to enhance its appearance with aerodynamic styling parts like front lip spoilers, rear trunk wings, or full-body kits. The 6th-generation (EK/EJ/EM) Civic from 1996–2000 is one of the most popular models for aftermarket modifications due to its lightweight chassis and JDM-inspired tuning culture. This guide breaks down everything you need to know about selecting, installing, and verifying compatibility for body kits on a 1999 Honda Civic—covering OEM vs. aftermarket options, material differences, fitment pitfalls, and installation considerations.

Understanding the 1999 Honda Civic Chassis and Body Styles

The 1999 Honda Civic was available in multiple configurations: coupe (EK3/4), sedan (EK2/5), and hatchback (EM1). Each has slightly different dimensions and mounting points for exterior components. ✅ Knowing your exact model type is essential before purchasing any body kit part. For example:

• EK chassis: Applies to 2-door and 4-door sedans/coupes
• EM chassis: Refers specifically to the 3-door hatchback (often called EK9 in JDM markets)
• Body style variations: Some trunks, bumpers, and fenders are not interchangeable between coupe and hatchback models

Using VIN lookup tools or checking under the hood for engine codes (like D16Y8 or B16A) can help confirm which variant you own. This matters because many aftermarket body kits are designed specifically for either the EK or EM platform—even within the same model year.

What Parts Are Included in a 'Body Kit'?

When users search for a 1999 Honda Civic body kit, they often mean more than just a full wrap-around package. Many buyers are actually seeking individual styling components such as:

• Front bumper lip / chin spoiler (🛒)
• Rear trunk spoiler / wing (🛒)
• Rear bumper diffuser or lip (🛒)
• Fender flares or side skirts (🛒)
• Full conversion kits (e.g., Type R look, Mugen style)

A complete body kit typically includes at least three of these elements, but some sellers market single pieces (like a rear spoiler) as part of a 'kit' for SEO purposes. ⚠️ Always verify what’s included before purchase.

Common Body Kit Types for the 1999 Civic

Different aesthetics drive demand for various styles. Here are the most popular categories:

1. OEM-Style Upgrades

These mimic factory-installed parts found on higher trims like the Si or EX. Examples include:

• OEM-style black rear decklid spoiler (common on coupes)
• Factory-fit front air dams used on Canadian or European models

✅ Pros: Direct bolt-on fitment, minimal modification required
❌ Cons: Less aggressive styling; harder to source genuine NOS (new old stock)

2. JDM-Inspired Kits

Based on Japanese Domestic Market designs, these offer a sportier profile. Popular themes include:

• Mugen-style front lips and rear wings
• Spoon Sports replica spoilers
• Type R conversion kits (especially for non-Si models)

⚙️ Note: True JDM parts may require minor trimming or drilling during installation. Look for terms like “direct fit” or “no modification needed” if you want plug-and-play compatibility.

3. Full Aero Packages

Brands like Seibon, Duraflex, and APR offer comprehensive kits that include front splitters, side skirts, and carbon fiber rear wings. These are often made from dry-carbon or fiberglass.

✨ Example: A Seibon SP Series Carbon Fiber Spoiler with integrated LED brake light offers both visual appeal and functional downforce.

Body Kit Type	Material	Avg. Price Range	Installation Difficulty
OEM Replica Spoiler	ABS Plastic	$35–$90	Easy (DIY)
JDM Front Lip	Polyurethane (PU)	$60–$130	Moderate
Carbon Fiber Wing	Dry Carbon/Fiberglass	$200–$1,300	Hard (Professional)
Complete Body Kit	Fiberglass	$400–$1,000	Very Hard

Key Materials Used in 1999 Civic Body Kits

Not all body kits are created equal. Material choice affects durability, weight, finish quality, and cost.

ABS Plastic

Commonly used for OEM-style spoilers and factory-replacement parts. It's impact-resistant and paintable.

• Best for: Rear trunk spoilers, small add-ons
• Pros: Durable, flexible, easy to paint
• Cons: Can warp over time in direct sun

Polyurethane (PU)

Flexible rubber-like material ideal for front lips and bumpers exposed to road debris.

• Best for: Chin spoilers, lower bumper extensions
• Pros: Resists cracking, absorbs minor impacts
• Cons: Harder to paint without proper prep; prone to sagging if poorly supported

Fiberglass

Widely used in budget full-body kits. Requires careful finishing before painting.

• Best for: Side skirts, widebody fenders
• Pros: Low cost, customizable shaping
• Cons: Brittle, can crack on impact; needs skilled installation

Carbon Fiber

High-end option, either real dry carbon or carbon-look vinyl wrap.

• Best for: Performance aesthetic upgrades
• Pros: Lightweight, premium appearance
• Cons: Expensive; fake versions often mislabeled as “carbon fiber” when they’re just printed plastic

🔍 Tip: Real carbon fiber feels slightly textured and shows weave depth. If it’s perfectly smooth and glossy, it might be a decal.

Fitment Considerations: Will It Work on Your 1999 Civic?

One of the biggest frustrations reported by owners is buying a part labeled “fits 1996–2000 Civic” only to discover it doesn’t match their specific trim or body style.

Chassis Code Matters

Even within the same model year, Civic variants differ:

• EK3/EK4: 2-door coupe – most common for body kits
• EK2/EK5: 4-door sedan – fewer kit options
• EM1: 3-door hatchback – often requires unique parts

📌 Always check product descriptions for explicit chassis compatibility (e.g., “Fits EK Coupe Only”).

Trim-Level Differences

The base DX, mid-level EX, and sporty Si trims have different bumper shapes and mounting holes. A body kit designed for an Si may not align with a DX bumper.

• Example: The 1999 Civic Si has a larger lower grille opening—some front lips won’t seal properly on non-Si bumpers
• Solution: Use universal-fit PU lips that allow slight adjustment, or modify the bumper

Year-Over-Year Changes

While 1996–2000 Civics share platforms, there were subtle updates:

• Taillight design changed slightly in 1998–1999
• Rear trunk lid shape varies between early and late EK models
• Some spoilers integrate third-brake lights; older models may lack wiring

✅ Pro tip: Compare dimensions using OEM part numbers (e.g., 64353-SV0-A00 for a rear spoiler) to ensure cross-compatibility.

Where to Buy a 1999 Honda Civic Body Kit

Purchasing decisions should balance price, authenticity, shipping time, and return policies.

Online Marketplaces

Websites like eBay and AliExpress list numerous options, but buyer beware:

• Check seller ratings and feedback focused on automotive parts
• Look for photos showing actual product, not just renderings
• Confirm whether the item ships from overseas (long delays possible)

🚚 International shipping can take 3–8 weeks and may incur customs fees.

Specialty Tuning Shops

Vendors like PRO Civic, Ikon Motorsports, or JHPU USA specialize in Honda accessories and usually provide detailed fitment guides.

• ✅ Benefits: Better customer support, technical documentation
• ❌ Drawbacks: Higher prices compared to generic sellers

Local Auto Body Suppliers

In Europe, sites like AKR-Performance.it or Ricambidieci.it offer localized inventory and faster delivery.

• 📍 Advantage: VAT-inclusive pricing, EU-based returns
• ⚠️ Watch out: Some Italian or German suppliers don’t ship outside their region

Installation Tips and Common Pitfalls

Installing a body kit isn’t always straightforward. Here’s what to expect:

Tools You’ll Need

• Socket wrench set
• Trim removal tools
• Double-sided tape (3M VHB recommended)
• Drill (if modifying brackets)

Step-by-Step Installation (Rear Spoiler Example)

1. Remove existing trunk lining to access mounting points
2. Clean surface thoroughly with isopropyl alcohol
3. Dry-fit spoiler to check alignment
4. Apply adhesive tape or use screws (if pre-drilled)
5. Reconnect wiring if LED-equipped
6. Test brake light function before finalizing

Common Issues During Installation

• Gaps between spoiler and trunk lid due to warped surfaces
• LED wiring not matching factory harness (requires splice-in adapter)
• Lips scraping ground on steep driveways (adjust ride height or choose low-profile design)

Aftermarket vs. OEM: Which Is Better?

This depends on your goals:

Choose OEM If:

• You want reliability and perfect fitment
• Planning to resell the car soon
• Prefer subtle enhancements

Choose Aftermarket If:

• You’re customizing for show or track use
• Seek aggressive styling (wide fenders, deep lips)
• Don’t mind potential rework or repainting

🔧 Reminder: Aftermarket fiberglass parts often arrive unpainted and require professional prep work.

Verifying Authenticity and Quality

With so many replicas online, distinguishing real performance parts from cheap copies is crucial.

• Check brand trademarks: Genuine Mugen or Spoon parts will have official logos and packaging
• Review product weight: Lightweight plastic may indicate thin molding
• Examine seam lines: Poorly aligned molds suggest low-quality manufacturing

🌐 Research forums like r/Honda or PakWheels to see real user reviews and installation photos.

Maintenance and Longevity

Once installed, body kits need care to last:

• Wash regularly to prevent dirt buildup in crevices
• Inspect mounting points every 6 months for loosening
• Touch up paint chips quickly to avoid rust or delamination
• For PU lips: Avoid high-pressure washers directly on edges

🧼 Use wax sparingly on matte-finish or carbon fiber parts to preserve texture.

Legal and Safety Considerations

In some regions, modified bumpers or protruding spoilers may fail vehicle inspections.

• 🇩🇪 Germany: Strict TÜV rules on ground clearance and protrusion limits
• 🇺🇸 USA: Varies by state; California has strict emissions and safety regulations
• 🇬🇧 UK: MOT test checks for sharp edges or excessive modifications

❗ Always research local laws before installing large aero components.

FAQs About 1999 Honda Civic Body Kits

Can I install a body kit myself?

Yes, simple add-ons like rear spoilers or front lips can be DIY with basic tools. Full kits involving fender flares or major bumper replacements are best left to professionals due to complexity and paint-matching requirements.

Do all 1999 Honda Civics have the same trunk spoiler mount?

No. Coupe and sedan models share similar mounting patterns, but hatchbacks (EM1) often differ. Additionally, Si trims may have pre-drilled holes where base models do not.

Are carbon fiber spoilers worth the price?

For show cars or enthusiasts, yes—they offer a premium look and slight weight savings. However, for daily drivers, ABS plastic or PU spoilers offer better value and durability against road hazards.

Why does my rear spoiler LED not work after installation?

This usually happens when the wiring harness isn't connected to the third brake light circuit. You may need to splice into the existing wiring or use an adapter harness sold separately.

Can I mix and match body kit parts from different brands?

You can, but mismatched materials (e.g., rigid fiberglass with flexible PU) may create uneven gaps or stress points. Also, color and gloss levels may vary between manufacturers.
