Car Nissan Silvia S14 became a true legend of Japanese drifting and street culture, but it was in combination with the aggressive style of Rocket Bunny that his appearance was transformed into something completely different. This project created by a master Tomokazu Matsui, offers not just visual changes, but a radical widening of the wheel arches, creating a powerful and muscular figure. Owners S14 often choose this route to stand out from the crowd of standard sedans and coupes, turning them into real monsters of the asphalt.
Installation Rocket Bunny is a complex engineering process that requires not only welding skills, but also a deep understanding of suspension geometry. Simply bolting on wide fenders is not enough; you need to prepare the body, strengthen the sills and select the right wheels with the required offset. Ignoring technical nuances can lead to the car losing controllability or even the integrity of the body during operation.
In this article we will look in detail at how to approach the project correctly. Silvia S14 Rocket Bunny, what mistakes beginners make and what you should pay attention to when choosing components. We will also touch on issues of compatibility of parts from different manufacturers and the specifics of adjusting the suspension to new dimensions.
The history of the Rocket Bunny style and design philosophy
Phenomenon Rocket Bunny originated in the mid-2000s thanks to a project by a master tuner Tomokazu Matsui, who worked for TRA Kyoto. His idea was to create an aerodynamic body kit that does not just “stick” to the car, but visually expands it, making it more aggressive and ready for extreme loads. The style is characterized by distinctive “ears” on the wings, huge air intakes and a massive rear spoiler.
This style looks especially impressive on the body Silvia S14, since the original lines of the car are quite smooth and streamlined. The contrast between the sleek factory body and the rough, angular elements of the kit creates a unique aesthetic that has become a benchmark in the world of JDM tuning. Owners often choose Rocket Bunnyto emphasize the sporty nature of the car and its readiness for competition.
It's important to understand that this style is not just a collection of plastic parts. This is a whole philosophy that involves maximum track width and low ground clearance. Every detail, from the front bumper to the rear diffuser, is designed with aerodynamics in mind, although it mainly plays a decorative role. However, proper installation can even improve engine and brake system cooling.
Kit selection and component compatibility
When choosing a whale for Nissan Silvia S14 It is important to distinguish between the official sets from TRA Kyoto and their replicas, which are produced in China or other countries. Official sets are made from quality fiberglass or polyurethane to ensure a precise fit and durability. Replicas can have serious geometric distortions, requiring time-consuming adjustment and puttying.
There are several variations of kits, which may differ in the degree of aggressiveness and the presence of additional elements. Some versions only include fender flares, while complete kits cover all areas of the body. When choosing, you must take into account that parts may not fit other generations Silvia, for example, S13 or S15, since their body geometry is different.
For successful installation you will need:
- ✅ Original or high-quality replica of the Rocket Bunny whale
- ✅ Set of fasteners and rivets
- ✅ Materials for preparing the body (primer, putty)
- ✅ Tools for cutting and welding
Pay attention to compatibility with other tuning elements. If you plan to install wide rims, make sure that the Rocket Bunny arches will not conflict with them. Sometimes additional adjustments to the inside of the fenders are required to allow the wheels to rotate freely.
Body preparation and cutting process
The first and most important stage is preparing the body. Before starting work, it is necessary to dismantle all standard body parts, including bumpers, sills and fenders. The body must be perfectly clean and dry so that you can accurately mark the cutting lines. Errors at this stage can lead to irreversible damage to the metal, which will require major repairs.
Marking is carried out using templates that usually come with the kit. However, you should not blindly trust them, since the car body may have slight deformations after use. Use a laser level and measuring instruments to ensure the lines are symmetrical. Draw the lines with a marker, and then check them visually from different angles.
The cutting process requires high precision and accuracy. Use special metal scissors or a grinder with a thin disc to avoid overheating and deformation of the metal. You need to cut strictly along the line, without going beyond it. After cutting, be sure to treat the edges of the metal with an anti-corrosion compound to prevent rust.
Installation of extended wings and arched elements
The installation of flared fenders is a key aspect that determines the appearance of the car. The Rocket Bunny fenders are attached to the body using bolts and rivets, ensuring a secure connection. However, before this, it is necessary to strengthen the sills and attachment points, since new elements create additional load on the body.
To install the wings correctly, you will need temporary fasteners that will allow you to adjust their position before final fastening. Make sure the gaps between the fenders and the body are even on all sides. This is not only important for aesthetics, but also affects the aerodynamics of the car.
It is important to note that installing widened fenders may require changes to the suspension geometry. If you plan to use wide wheels with negative camber, make sure that the fenders will not hit the tires when cornering or on uneven roads. Sometimes additional processing of the inside of the wings is required.
Modernization of suspension to new dimensions
With the installation of wide Rocket Bunny arches, the car inevitably changes its dynamic characteristics. A wider track means the suspension operates under different conditions, and the stock springs or shock absorbers may not be able to cope with the new load. It is necessary to review the camber, toe and ride height settings.
To achieve optimal handling, it is recommended to install adjustable shock absorbers (coilovers), which will allow you to fine-tune the stiffness and height of the body. It is also worth paying attention to the suspension arms, which may require replacement with reinforced or adjustable models to correct wheel alignment angles.
Don't forget about the braking system. Increasing the diameter of wheels and tires may require the installation of stronger brake calipers and rotors. This is especially important if you plan to use the car for drifting or track racing.
Key points for setting up the suspension:
- ✅ Installation of adjustable shock absorbers
- ✅ Replacement of levers with reinforced models
- ✅ Correction of wheel alignment angles
- ✅ Checking the operation of the brake system
- Standard
- Adjustable springs
- Air suspension
- Coilovers with tuning

Finishing and painting
After installing all the elements, the finishing stage begins. The seams between the new parts and the body must be carefully filled and sanded so that they become invisible. This is a labor-intensive process that requires patience and skill, but it is what determines the final quality of the work.
Painting of Rocket Bunny elements must match the color of the car body. If you are using fiberglass parts, they will need to be primed and prepped for painting. It is recommended to use high-quality paint and varnish that are resistant to ultraviolet radiation and precipitation.
Pay special attention to the joints between parts. They should be perfectly even and smooth, without visible transitions. If you are not confident in your abilities, it is better to entrust this stage to professional painters who have experience working with aerodynamic kits.
⚠️ Attention: Don't skimp on the quality of paint and varnish. Cheap materials can quickly fade or crack, ruining the appearance of the car.
What to do if the parts don't fit?
If the parts do not fit perfectly, do not attempt to install them. It is better to return them to the seller or look for alternative options. Improper installation may result in body damage and safety issues.
Vehicle operation and maintenance
After all work is completed, the car is ready for use. However, it is worth remembering that extended arches and new body kit elements require additional care. Regularly inspect mounting points for corrosion and loose bolts. Dust and dirt can accumulate in hard-to-reach places, so washing your car should be more thorough.
Be careful when driving on rough roads, as the low ride height and wide arches may be vulnerable to damage. Avoid sharp impacts on curbs and holes to avoid damaging fragile parts of the body kit. If you plan to use the car for drifting, make sure all fasteners are securely tightened.
Regular checks of the condition of the suspension and braking system are also mandatory. The increased load on these nodes requires more frequent monitoring of their performance. Don't ignore strange sounds or changes in your vehicle's behavior, as they may indicate problems.
