2. Exterior Modifications

The exterior is the first thing anyone notices. Customizing it can range from basic to extreme.

Popular Upgrades

  • Body Kits and Ground Effects
    Add-ons like front and rear bumpers, side skirts, and spoilers create a sportier or aggressive profile. Kits often come as four or five-piece sets designed specifically for the 1999 Civic 4-door.

  • Aftermarket Wheels and Tires
    Upgrading to larger, lighter, or uniquely styled wheels instantly changes your car’s vibe. Choose wheel sizes and offsets that don’t cause rubbing or poor handling.

  • Headlight and Taillight Upgrades
    Projector, halo, or LED lights can bring your Civic’s look into the modern era and improve nighttime visibility.

  • Window Tinting
    Tint not only boosts privacy, but also protects interiors and gives a sleek appearance.

  • Custom Paint or Vinyl Wraps
    For maximum visual impact, consider bold colors, unique finishes, or even full vinyl wraps for an ever-changing look.

Practical Tips

  • Match body kits to your model year and door count for proper fit.
  • Professional installation is highly recommended for body kits and paint to guarantee a clean result.
  • Check local laws regarding headlight modifications and window tint percentages.

3. Interior Upgrades

Give your driving experience a boost with functional and aesthetic improvements inside.

Common Interior Mods

  • Aftermarket Seats and Steering Wheels
    Racing seats can provide better support, while steering wheels offer customization in both look and feel.

  • Upgraded Audio Systems
    Swap in new speakers, touch-screen head units, subwoofers, or amplifiers for superior sound.

  • Floor Mats, Shift Knobs, and Pedals
    Personalize with color-matched or logo-etched accessories.

  • Gauge Clusters and Accent Lighting
    Light up your dash and add gauges for performance monitoring.

Best Practices

  • Ensure aftermarket steering wheels and seat belts comply with safety regulations.
  • When modifying wiring (for audio or lighting), use proper harnesses and fuses to prevent electrical issues.

4. Performance Enhancements

Even the humble 1999 Civic can offer spirited driving with the right go-fast parts.

Top Performance Mods

  1. Cold Air Intake Systems
    Improve airflow for a slight bump in horsepower and better engine sound.

  2. Exhaust Upgrades
    Headers, mid-pipes, and cat-back exhaust systems enhance power and add a performance growl.

  3. Suspension Components
    Lowering springs, coilovers, or sway bars reduce body roll and offer a more aggressive stance.

  4. Brake Kits
    Larger rotors and stronger calipers improve stopping power—crucial if you add more speed.

  5. Engine Tuning and ECU Chips
    Adjusting fuel and ignition parameters can unlock extra performance, especially when combined with other mods.

  6. Turbocharging or Engine Swaps (Advanced)
    For serious enthusiasts, adding a turbo kit or swapping in a higher-output Honda engine can massively increase power.

Points to Remember

  • Upgrade in stages and assess gains after each step.
  • Always pair increased power with better suspension and braking for safety and control.

5. Finding and Ordering Custom Parts

The 1999 Civic’s popularity means many shops offer custom components:

Major Categories of Aftermarket Parts

  • Body Kits, Spoilers, and Grilles
  • Wheels, Tires, and Suspension Kits
  • Lighting Upgrades (LED, Projectors, Under glow)
  • Performance Exhausts and Intakes
  • Audio and Electronic Accessories

Shopping Advice

  • Compare prices across multiple suppliers to find the best deal.
  • Prioritize brands known for fitment and durability.
  • Carefully check item descriptions—many parts are specific to the four-door model.
  • For larger items like body kits, factor in significant shipping costs and delivery times.
  • When possible, consolidate orders to reduce shipping expenses.

Cost Tips

  • Shop during off-season sales or promotions for large discounts.
  • Seek local sellers or online community groups for gently used parts.
  • Base-level mods like intake or lighting upgrades are budget-friendly, while full kits, wheels, and paint jobs can become costly.

6. Potential Challenges and How to Avoid Them

While customizing is exciting, be mindful of these common hurdles:

  • Fitment Problems: Some aftermarket parts may not align perfectly. Check compatibility thoroughly before purchasing.
  • Legal Restrictions: Local laws may limit tint darkness, ride height, exhaust noise, or lighting modifications.
  • Budget Overruns: Set a clear budget and prioritize must-have mods.
  • Insurance Considerations: Customizations can affect premiums or coverage. Notify your insurer of major changes.
  • DIY Issues: For advanced jobs, improper installation can cause headaches. Use professional installers for body, paint, and complex mechanics.

7. Showcasing Your Custom Honda Civic

Once you’ve completed your project:

  • Attend local car meets or organized shows to display your creation.
