Understanding the IG37 Coupe Sport Bumper Conversion

Before diving into the installation, it's crucial to understand what the IG37 Coupe Sport Bumper Conversion entails. The conversion typically involves replacing the stock front bumper with a sport-style bumper. This new bumper is designed to give the car a more aggressive and modern look, often incorporating features like a more pronounced front lip, larger air intakes, and sometimes integrated fog lights or LED daytime running lights (DRLs). The design of a sport bumper is usually more streamlined and aerodynamic, which can contribute to improved airflow and potentially enhance the car's performance at higher speeds. The sport bumper is designed to replace the original bumper, integrating seamlessly with the existing body panels and mounting points. This conversion is a popular choice among G37 Coupe owners looking to personalize their vehicles and give them a more unique appearance. The sport bumper is an aftermarket part, meaning it is not manufactured by Infiniti itself but by specialized companies. You'll find a wide variety of designs, materials, and finishes to choose from, allowing you to tailor the look to your exact preferences.

One of the first things to consider is the design of the sport bumper. There are many different styles available, each offering a unique aesthetic. Some bumpers have a more subtle, understated look, while others are more aggressive and attention-grabbing. You’ll want to consider your personal style and the overall look you want to achieve. Material selection is another key factor. Sport bumpers are commonly made from materials like polyurethane, fiberglass, and carbon fiber. Polyurethane is known for its flexibility and durability, making it resistant to minor impacts. Fiberglass is a more affordable option but can be prone to cracking if not handled carefully. Carbon fiber is the premium choice, offering high strength, light weight, and a distinctive look, but it comes with a higher price tag. The choice of material can significantly impact the cost, appearance, and longevity of your sport bumper. Before you start with the installation, make sure to consider the preparation. You’ll need to prep the new bumper before you install it on your car. This often involves sanding down any imperfections and priming the surface, so it is ready for paint. Getting the right finish is an important aspect of the conversion. When the conversion is done correctly, your car will look stunning, and you'll love the new appearance.

Preparation

Safety First: Before starting, ensure your car is parked on a level surface. Wear safety glasses, gloves, and a mask.
Lift the Vehicle: Use a jack to lift the front of the car and secure it with jack stands. This provides adequate space to work under the bumper.
Remove the Existing Bumper: Locate and remove the fasteners holding the stock bumper in place. These typically include bolts, screws, and clips located along the top, sides, and bottom of the bumper. Use the panel removal tools to carefully detach any clips.
Disconnect Wiring: If your car has fog lights or other electrical components connected to the bumper, disconnect the wiring harnesses. Take pictures to remember the connections.
Carefully Detach: Once all fasteners and wiring are disconnected, carefully pull the bumper away from the car. It might be helpful to have an assistant to support the bumper.

Bumper Preparation

Inspect the New Bumper: Examine the new sport bumper for any imperfections or damage.
Test Fit: Before painting, do a test fit of the new bumper to ensure it aligns correctly with the car's body panels and mounting points.
Prep for Paint: Sand the bumper surface to ensure it is smooth and ready for paint. Apply primer according to the manufacturer's instructions.
Painting: Apply several coats of paint, allowing each coat to dry before applying the next. Finish with a clear coat for added protection and shine.

Installation

Position the Bumper: Carefully align the sport bumper with the car's front end.
Attach the Bumper: Secure the bumper using the provided or new hardware. Start with the main mounting points and work your way around, ensuring everything aligns correctly.
Connect Wiring: Reconnect any wiring harnesses for fog lights or other electrical components. Make sure the connections are secure.

Painting and Finishing the Sport Bumper

Painting and finishing the IG37 Coupe Sport Bumper is a critical step that impacts the final appearance of your car. A high-quality paint job not only enhances the look but also protects the bumper from the elements. Here’s how to achieve a professional finish:

Preparing the Bumper

Sanding: Begin by thoroughly sanding the bumper. If your bumper is made of fiberglass or has any imperfections, start with a coarser grit sandpaper (e.g., 220 grit) to smooth out the surface. Progress to finer grits (e.g., 400 or 600 grit) to achieve a smooth surface. This sanding process is crucial for the paint to adhere properly.
Cleaning: Clean the bumper with a degreaser or wax and grease remover to remove any contaminants, such as oil, dirt, and wax. Use a clean, lint-free cloth to wipe the surface.
Priming: Apply a primer specifically designed for automotive use. Primer provides a base for the paint to adhere to and helps to even out the surface. Apply the primer in even coats, following the manufacturer's instructions. Allow the primer to dry completely before proceeding to the next step.

Painting the Bumper

Color Matching: Ensure the paint color matches your car's existing paint. You can find your car's paint code on a sticker inside the driver’s side doorjamb. You can then take this code to an auto parts store to get the correct paint.
Applying the Base Coat: Apply the base coat of paint in several thin, even coats, allowing each coat to dry slightly before applying the next. This helps to prevent runs and ensures good coverage. Maintain a consistent distance from the bumper and use smooth, even strokes.
Clear Coat: Once the base coat is completely dry, apply several coats of clear coat. Clear coat protects the base coat and provides a glossy finish. Apply the clear coat in the same manner as the base coat, using thin, even coats.
Drying and Curing: Allow the paint to dry and cure completely according to the manufacturer's instructions. This might take several days.

Finishing Touches

Wet Sanding and Polishing: Once the clear coat is fully cured, you might wet sand it with very fine sandpaper (e.g., 2000 or 3000 grit) to remove any imperfections. After sanding, polish the bumper with a polishing compound to restore its shine.
Waxing: Apply a coat of wax to protect the paint and enhance the shine.

Troubleshooting Common Issues

Even with the best planning, you might encounter some issues during your IG37 Coupe Sport Bumper Conversion. Being prepared for these challenges can save you time and frustration. Here are some common problems and solutions:

Alignment Issues

Problem: The new bumper doesn’t align perfectly with the car’s body panels.
Solution: Check the mounting points to make sure they are not damaged. Loosen the mounting bolts and try to adjust the bumper slightly. If the misalignment is minor, you might be able to gently flex the bumper into place. If the misalignment is significant, you might need to modify the mounting points or consult with a professional.

Poor Paint Finish

Problem: The paint job has runs, drips, or an uneven finish.
Solution: Ensure the surface is properly prepared by sanding and cleaning. Apply thin, even coats of paint. If you get runs or drips, allow the paint to dry completely and then wet sand the imperfections before applying another coat.

Hardware Issues

Problem: The provided hardware doesn’t fit or is missing.
Solution: Check the hardware before you start the installation. Use the correct sized tools to install it properly. If any hardware is missing, it is best to go to a hardware store and get the correct replacement.
