Rocket Bunny 240sx Kit: Installation Tips & Widebody Pros/cons

The Nissan 240SX, particularly the S13 and S14 generations, has cemented its place as a drifting icon and a platform ripe for modification. Among the most visually striking and impactful modifications is the widebody kit, and few are as recognizable and coveted as the Rocket Bunny/Pandem kit. While the aggressive aesthetics are undeniable, the process of installing such a kit and living with a widebody car requires careful consideration. This guide delves into the installation process and explores the pros and cons of embracing the Rocket Bunny look for your 240SX.

Rocket Bunny 240SX Kit: A Closer Look

The Rocket Bunny kit, designed by TRA Kyoto in Japan, fundamentally alters the 240SX's body lines. These kits are typically constructed from Fiber Reinforced Plastic (FRP), chosen for its relatively low cost and ease of molding. However, it's crucial to understand that FRP requires a meticulous preparation and installation process to achieve a flawless finish. Each kit usually consists of:

Front and rear over-fenders
Front and rear bumpers (or bumper extensions)
Side skirts
Ducktail spoiler (often optional)

Some kits also include additional components like canards and diffusers, further enhancing the car's aggressive appearance and potentially its aerodynamic performance.

Installation: A Step-by-Step Guide

Installing a Rocket Bunny kit is not a simple bolt-on affair. It requires a significant amount of cutting, drilling, and bodywork. It's strongly recommended that this task be undertaken by experienced individuals or professionals with expertise in body modification. Here's a general overview of the process:

1. Preparation and Assessment

Before touching any tools, thoroughly inspect all components of the kit. Check for any damage incurred during shipping. Dry-fit all panels to the car *before* making any cuts. This crucial step allows you to visualize the final product and identify potential fitment issues early on. Mark any areas that require trimming or adjustment. Don't assume the kit will fit perfectly out of the box; some level of modification is almost always required. This is especially true for replica kits.

2. Fender Cutting

This is the most daunting part of the installation. The factory fenders need to be cut to accommodate the wider over-fenders. Carefully mark the cut lines based on the dry-fitment. Use a cut-off wheel or air saw to make the cuts. *Take your time and be precise.* Err on the side of caution and remove less material initially; you can always trim more later. Ensure the cut edges are clean and smooth to prevent rust.

Important Note: Wear appropriate safety gear, including eye protection and a respirator, when cutting fiberglass and metal.

3. Over-Fender Mounting

With the fenders cut, you can now mount the over-fenders. Rocket Bunny kits typically utilize rivets or bolts to secure the over-fenders to the body. Drilling holes for the rivets or bolts requires careful alignment and precision. Use masking tape to mark the hole locations and ensure they are evenly spaced. Apply rust preventative to any exposed metal after drilling.

Some installers choose to weld the over-fenders to the body for a seamless look. This requires advanced welding skills and can be more time-consuming, but it results in a cleaner and more durable finish. Remember to properly prep the metal for welding and take necessary safety precautions.

4. Bumper and Side Skirt Installation

The installation of bumpers and side skirts typically involves removing the factory components and bolting on the new Rocket Bunny parts. However, modifications may be required to ensure proper alignment and fitment. You may need to fabricate custom brackets or trim the parts to achieve a seamless integration with the rest of the body.

5. Bodywork and Finishing

Once all the components are mounted, the real bodywork begins. Any gaps or imperfections need to be addressed with body filler. This is a crucial step in achieving a professional-looking finish. Sand the body filler smooth and ensure a consistent surface for paint. Several layers of primer are required to create a smooth base for the final coat of paint.

6. Painting

Painting the kit is best left to professionals. Achieving a perfect color match with the existing paint and applying the paint evenly requires specialized equipment and expertise. Consider the finish you desire: a glossy, show-quality paint job or a more utilitarian, track-focused finish. The choice will impact the cost and complexity of the paint job.

Widebody Pros and Cons

Beyond the visual appeal, a widebody kit has both advantages and disadvantages that potential owners should consider.

Pros:

Aggressive Aesthetics: The most obvious benefit is the dramatic change in appearance. A Rocket Bunny kit transforms the 240SX into a head-turning machine.
Increased Tire Clearance: The wider fenders allow for the fitment of wider wheels and tires. This improves grip and handling, particularly for drifting or track use.
Improved Aerodynamics (Potentially): While not all widebody kits are designed with aerodynamics in mind, some offer subtle improvements in airflow and downforce. A properly designed kit, when coupled with a rear wing and front splitter, can significantly enhance performance. However, poorly designed kits can actually *increase* drag.
Enhanced Cooling (Potentially): Some widebody kits feature larger openings for brake cooling ducts, improving brake performance and longevity under demanding conditions.

Cons:

Significant Cost: The cost of the kit itself, combined with the cost of professional installation and painting, can be substantial. This can easily exceed several thousand dollars.
Complex Installation: As detailed above, the installation process is complex and time-consuming, requiring specialized skills and tools.
Reduced Resale Value (Potentially): While some enthusiasts appreciate the modifications, a heavily modified car may not appeal to all buyers. This can potentially reduce the resale value of the vehicle.
Increased Weight: The added body panels and modifications can add weight to the car, potentially impacting performance. While the weight gain isn't enormous, it's something to consider.
Practicality Issues: The wider body can make the car more difficult to maneuver in tight spaces. Curb rash becomes a bigger concern. Also, accessing certain components underneath the car may become more challenging.
Potential for Damage: The FRP material is more susceptible to damage than the factory steel body panels. Minor impacts can easily crack or chip the fiberglass.
Maintenance: Widebody kits require ongoing maintenance to keep them looking their best. This includes regular cleaning, waxing, and repairs to any damage.

Alternatives and Considerations

Before committing to a Rocket Bunny kit, consider the alternatives. Less extreme widebody options exist, such as bolt-on fender flares. These offer a wider stance without the need for extensive cutting. Also, consider your overall goals for the car. If you're primarily interested in improving handling, focusing on suspension upgrades and performance tires may be a more cost-effective approach. If aesthetics are the main priority, explore other body kit options that may be easier to install and maintain.

Furthermore, authentic Rocket Bunny kits are expensive. Many replica kits are available, often at significantly lower prices. However, the fit and finish of replica kits can vary greatly. Be prepared to spend extra time and effort to ensure a proper fit. Research reviews and forums to gauge the quality and reputation of different replica manufacturers.

Conclusion

The Rocket Bunny widebody kit is a significant undertaking that transforms the 240SX into a visually stunning and potentially higher-performing machine. However, it's crucial to carefully weigh the pros and cons before taking the plunge. The installation process is complex and requires specialized skills, and the long-term maintenance can be demanding. But for those who are prepared to invest the time, effort, and money, a Rocket Bunny 240SX can be a truly rewarding project that stands out from the crowd.
