Performance Upgrades for Your ’99 Civic: Engine, Drivetrain, & Brakes
This is where many enthusiasts start, seeking to extract more power and improve the driving dynamics. These 1999 Honda Civic custom tips will help you make informed decisions.
Engine Enhancements: Power & Efficiency
The ’99 Civic came with D-series engines (D16Y7, D16Y8), known for their reliability and fuel efficiency. However, they can be significantly upgraded.
-
Bolt-On Modifications:
- Intake: A cold air intake (CAI) or short ram intake can improve throttle response and add a few horsepower.
- Exhaust: A cat-back exhaust system can free up exhaust flow and provide a sportier sound.
- Header: Upgrading the exhaust header can further improve flow, especially with a performance cat-back.
- ECU Tuning: After bolt-ons, a custom ECU tune (e.g., Hondata S300) is essential to maximize gains and ensure optimal air/fuel ratios. This is often best left to a professional tuner.
-
Engine Swaps:
- B-Series (B16A, B18C): A very common and rewarding swap, offering significant power boosts. Requires new engine mounts, wiring harness, and often a different transmission.
- K-Series (K20A, K24A): The modern gold standard for Honda swaps, offering immense power potential. This is a more complex and costly swap, requiring specialized mounts, wiring, and fabrication.
When performing engine work, always disconnect the battery and ensure proper torque specifications are used for all fasteners. Safety first!
Suspension & Handling: Grip and Ride Quality
Improving your Civic’s handling is crucial, especially if you’re adding power. A well-tuned suspension makes the car feel more responsive and planted.
- Coilover Suspension: Adjustable coilovers allow you to dial in ride height, damping, and sometimes even camber, offering significant handling improvements. Brands like Tein, BC Racing, and Skunk2 are popular.
- Bushings: Replacing old rubber bushings with polyurethane alternatives can reduce suspension slop and improve feedback.
- Sway Bars: Upgraded front and rear sway bars (anti-roll bars) reduce body roll during cornering, enhancing stability.
- Strut Tower Braces: These simple bolt-on bars stiffen the chassis, reducing flex and improving steering response.
After any suspension work, a professional alignment is absolutely necessary to ensure proper tire wear and safe handling. Don’t skip this step!
Stopping Power: Brake System Upgrades
More power demands more stopping power. Don’t overlook brake upgrades for your 1999 Honda Civic custom build.
- Pads & Rotors: Performance brake pads (e.g., Hawk HPS, EBC Yellowstuff) and slotted/drilled rotors offer improved stopping power and fade resistance over stock.
- Brake Lines: Stainless steel braided brake lines reduce flex under pressure, providing a firmer pedal feel.
- Caliper Upgrades: Swapping to larger calipers (e.g., from an Integra Type R or certain Acura models) can dramatically increase braking performance. This often requires larger rotors and possibly new wheels.
- Brake Fluid: Upgrade to a high-performance DOT 4 or DOT 5.1 fluid for better heat resistance, especially if you plan on spirited driving.
Always bleed your brake lines thoroughly after any brake system work to remove air bubbles, which can cause a spongy pedal. Use fresh, clean brake fluid.
Exterior & Interior Customization: Style That Stands Out
Once the performance is dialed in, or even as a standalone project, giving your Civic a unique look is incredibly satisfying. This 1999 Honda Civic custom guide covers the aesthetic aspects.
Aesthetic Transformations: Body & Paint
The EK Civic has a clean, timeless design, but there’s plenty of room for personalization.
- Body Kits & Aero: Front lips, side skirts, rear diffusers, and spoilers can drastically change the car’s profile. Choose quality fiberglass or ABS plastic for durability.
- Paint & Wraps: A fresh paint job or a vinyl wrap can completely transform the car’s appearance. Consider unique colors or finishes.
- Lighting: Upgraded headlights (e.g., projector retrofits, LED bulbs) and taillights can modernize the look and improve visibility.
- Window Tint: Adds privacy and can enhance the car’s aggressive stance. Check local laws regarding tint percentages.
For major bodywork or paint, consider professional help. A good paint job requires significant skill and equipment.
Wheels & Tires: The Right Stance
Wheels and tires are arguably the most impactful aesthetic and performance modification you can make.
- Wheel Selection: Choose wheels that complement your car’s style and performance goals. Common sizes for the EK are 15-17 inches. Consider offset and width carefully to avoid rubbing.
- Tire Choice: High-performance summer tires offer superior grip for spirited driving. All-season tires are a good balance for daily drivers in varied climates.
- Wheel Spacers: Can be used to achieve a wider stance, but use with caution and ensure proper hub-centric fitment.
Always ensure your chosen wheel and tire combination clears your fenders and suspension components, especially if you’ve lowered the car. A test fit is highly recommended.
Interior Comfort & Tech Upgrades
Don’t forget the space where you spend all your time!
- Seats: Aftermarket bucket seats or reclinable sport seats improve support and comfort, especially during spirited driving.
- Steering Wheel: A smaller, sportier steering wheel can enhance driving feel and aesthetics. Ensure airbag compatibility or consider an airbag delete for track use only.
- Audio System: Upgrade head unit, speakers, and add a subwoofer for a premium sound experience.
- Gauges: Install aftermarket gauges (oil pressure, water temp, AFR) to monitor critical engine parameters, especially on modified cars.
- Shift Knob & Bushings: A weighted shift knob and short shifter kit with upgraded bushings can make gear changes crisper and more enjoyable.
When working with interior electronics, always disconnect the battery to prevent accidental shorts or airbag deployment.
Sustainable & Eco-Friendly 1999 Honda Civic Custom
Customizing your Civic doesn’t have to be at odds with environmental responsibility. Embracing sustainable 1999 Honda Civic custom practices can make your build even more meaningful.
