Nissan Sentra Wide Body Kit

So, you're thinking about slapping a wide body kit on your Nissan Sentra, huh? Awesome! A properly installed wide body kit can dramatically transform the look of your ride, giving it an aggressive stance and allowing you to run wider tires for improved grip. But it's not just a bolt-on affair. This article dives deep into what's involved, from choosing the right kit to the nitty-gritty of installation, so you know exactly what you're getting into.

Understanding Wide Body Kits

Let's start with the basics. A wide body kit, at its core, replaces or adds to your car's existing fenders (front) and quarter panels (rear) to create more wheel well space. This allows you to fit significantly wider wheels and tires, which not only looks cool but also improves handling, especially on a track or in autocross events. The key is understanding the different types and materials.

Types of Wide Body Kits

There are primarily two types: bolt-on and molded (sometimes called "full replacement").

Bolt-on kits: These are generally easier to install and less expensive. They consist of over-fenders that are attached to the existing body panels using rivets, screws, or adhesive. While simpler, they often require cutting the original fenders to allow the wider wheels and tires to fit without rubbing. The aesthetic outcome can vary; some look seamless, while others have a more "riveted" or "flared" appearance.
Molded kits (Full Replacement): These are more complex and require significantly more bodywork. They involve cutting away the entire existing fender and quarter panel and welding or bonding the new, wider panels in their place. This results in a cleaner, more integrated look but demands a higher level of skill and specialized tools.

Material Matters: Fiberglass, Polyurethane, and Carbon Fiber

The material of the kit plays a huge role in its durability, fit, and cost. Let's break down the most common options:

Fiberglass (FRP): This is the most common and affordable option. Fiberglass kits are relatively lightweight and can be easily repaired. However, they are also brittle and prone to cracking or shattering if impacted. The fit and finish often require more work to achieve a perfect seamless look, often requiring significant sanding and filling.
Polyurethane (PU): Polyurethane is more flexible and durable than fiberglass. It's less likely to crack under stress but can still be damaged by significant impacts. PU kits generally have better fitment than fiberglass, requiring less modification before installation. It's a good balance of price and durability.
Carbon Fiber: The holy grail of body kit materials. Carbon fiber is incredibly strong, lightweight, and visually stunning. However, it's also the most expensive option and can be difficult to repair. The fitment is usually excellent, but the cost is a major deterrent for most.

Choosing the right material depends on your budget, skill level, and desired aesthetic. For a first-time project, polyurethane might be the best choice due to its forgiving nature and relatively good fitment.

Choosing the Right Kit for Your Sentra

Not all wide body kits are created equal. Before you hit "buy," consider these factors:

Fitment: Read reviews and check forums for feedback on the kit's fitment on your specific year and model of Sentra. Some kits are known to require extensive modification to fit properly, while others are almost a perfect match right out of the box. Look for kits that are specifically designed for your Sentra generation (e.g., B15, B16, B17, or B18).
Style: Wide body kits come in various styles, from subtle flares to aggressive, race-inspired designs. Choose a kit that complements the existing lines of your Sentra and reflects your personal taste. Consider the overall look you're trying to achieve.
Quality: Research the manufacturer and look for kits with good reputations for quality and customer service. A reputable manufacturer will use better materials and have stricter quality control processes, resulting in a better product overall.
Completeness: Does the kit include all the necessary hardware and instructions? Some kits only include the fenders and quarter panels, while others include side skirts, front and rear bumpers, and even mounting hardware. Make sure you know what you're getting.

Pro Tip: Join Sentra-specific online forums or Facebook groups. These communities are a goldmine of information, and you can often find firsthand experiences and recommendations for specific wide body kits.

The Installation Process: A Detailed Overview

Okay, you've got your kit. Now comes the fun part (or the challenging part, depending on your perspective). Here's a general overview of the installation process. Remember, safety first! Wear appropriate safety gear, including eye protection, gloves, and a respirator when sanding or working with fiberglass.

1. Preparation

Inventory: Unpack the kit and carefully inventory all the parts. Compare them to the parts list and make sure nothing is missing.
Test Fit: Before you start cutting or drilling, test fit the panels to your car. This will give you a good idea of how they line up and where you might need to make adjustments. This is *crucial*.
Marking: Using masking tape and a marker, carefully mark the areas where you will need to cut the original fenders. Be precise! It's better to cut too little and then trim more later than to cut too much and have a gap.
Wheel & Tire Mockup: Place your desired wheel and tire combo to check for clearance. This is very important. You may need to make further adjustment to the cut lines.

2. Cutting (If Required)

This is where things get real. If you're installing a bolt-on kit, you'll likely need to cut away sections of the original fenders to create clearance for the wider wheels and tires. Use a cutting wheel or a reciprocating saw with a metal cutting blade. Be careful not to damage any wiring or brake lines behind the fenders.

Important: Apply rust-inhibiting primer to all cut edges to prevent corrosion. This is a MUST.

3. Mounting

Bolt-on Kits: Use rivets, screws, or adhesive to attach the over-fenders to the existing body panels. Drill pilot holes for the rivets or screws. Use high-quality automotive adhesive for a strong bond. Ensure proper alignment before permanently attaching the panels.
Molded Kits: This is a much more involved process that typically requires welding. If you're not experienced with welding, it's best to leave this to a professional body shop. After welding, you'll need to grind down the welds, apply body filler, and sand everything smooth.

4. Bodywork

Even with the best-fitting kit, you'll likely need to do some bodywork to achieve a seamless look. This involves using body filler (e.g., Bondo) to fill in any gaps or imperfections, then sanding everything smooth. Start with a coarse grit sandpaper and gradually work your way up to a finer grit for a smooth finish.

5. Painting

Once the bodywork is complete, it's time to paint. This is another area where it's best to leave it to the professionals if you want a perfect finish. A professional paint job will ensure that the paint matches the existing color of your car and that the finish is smooth and durable.

6. Final Touches

After the paint has dried, install any remaining hardware, such as fender liners or trim pieces. Reinstall the wheels and tires and admire your handiwork!

Potential Challenges and Considerations

A wide body kit installation isn't without its challenges. Be prepared for these:

Fitment Issues: As mentioned earlier, some kits may require extensive modification to fit properly. This can be time-consuming and frustrating.
Rust Prevention: Cutting the original fenders exposes bare metal, which can lead to rust. Be sure to apply rust-inhibiting primer to all cut edges.
Alignment: Proper alignment of the wide body panels is crucial for a good-looking and functional result. Take your time and be precise when marking and cutting.
Cost: A wide body kit installation can be expensive, especially if you're hiring a professional body shop to do the work. Factor in the cost of the kit, materials, paint, and labor.
Legality: Check your local laws regarding wide body kits. Some jurisdictions may have restrictions on how far the wheels can extend beyond the fenders.

Conclusion

Installing a wide body kit on your Nissan Sentra is a challenging but rewarding project. It's a great way to personalize your car and improve its performance. By understanding the different types of kits, materials, and installation processes, you can make an informed decision and achieve a stunning result. Remember to take your time, be patient, and don't be afraid to ask for help when you need it. Good luck, and happy modding!
