The Mazda RX-7, a name synonymous with rotary engine performance and iconic styling, has always been a favourite among enthusiasts looking to push the boundaries of automotive artistry. While the stock RX-7 is a beautiful machine, some owners take their passion to an entirely new level, transforming these already legendary cars into bespoke masterpieces. One such example is a recently showcased RX-7 that has undergone a dramatic and visually arresting overhaul, centred around a colossal widebody kit that redefines the car's already aggressive stance.
The Ronin Speedworks Widebody: A Statement of Intent
At the heart of this RX-7's transformation is a giant Ronin Speedworks widebody. This isn't a subtle enhancement; it's a full-blown assault on conventional proportions, widening the car by a staggering more than 6 inches over the stock body. This significant increase in width isn't merely for aesthetic shock value; it's a functional necessity to accommodate some truly impressive rubber. The wider fenders and quarter panels allow for the fitment of 285mm wide tyres on each corner of the vehicle. Such substantial footwear provides an enormous contact patch, crucial for maximising grip and handling, especially in a car renowned for its agile chassis and potent power delivery.
The artistry of the Ronin Speedworks kit is evident in its aggressive lines and purposeful design. It seamlessly integrates with the RX-7's original silhouette, exaggerating its muscular curves and giving it an almost supercar-like presence. The flared arches, extended sills, and redesigned rear bumper all contribute to a cohesive and menacing aesthetic. This widebody isn't just about making the car wider; it's about creating a more dominant and visually impactful machine that commands attention wherever it goes.
RE Amemiya Aero: JDM Purity and Performance
Complementing the aggressive stance of the widebody is a selection of high-quality exterior components from the legendary Japanese tuning house, RE Amemiya. RE Amemiya is a name that resonates deeply within the rotary community, known for its dedication to rotary engine development and its distinctive, race-inspired styling. The RX-7 in question features a front bumper and spoiler from this esteemed manufacturer.
The RE Amemiya front bumper is a masterclass in functional design. It typically features larger air intakes to improve cooling for the engine and brakes, while the integrated spoiler helps to manage airflow at the front of the car, reducing lift and enhancing stability at higher speeds. The design is often characterised by its clean lines and purposeful aerodynamic elements, which not only look fantastic but also serve a crucial performance purpose. When paired with the widebody, these RE Amemiya pieces create a front end that is both incredibly aggressive and aerodynamically sound.
The Impact of Wider Tyres
The decision to fit 285mm wide tyres is a significant one, impacting various aspects of the RX-7's performance. With such a substantial contact patch, the potential for improved acceleration, braking, and cornering grip is immense. However, it also presents challenges:
- Suspension Tuning: The wider track width and increased tyre size necessitate careful suspension setup. Adjustments to camber, caster, and toe angles are crucial to optimise tyre wear and handling characteristics.
- Wheel Offset: Finding the correct wheel offset is vital to ensure the wider tyres clear the bodywork and suspension components without rubbing, especially under full suspension travel or steering lock.
- Steering Effort: Wider tyres can increase steering resistance, potentially making the steering feel heavier, particularly at lower speeds.
- Fuel Economy: Increased rolling resistance from wider tyres can lead to a slight decrease in fuel efficiency.
A Symphony of Style and Engineering
This modified RX-7 is more than just a collection of aftermarket parts; it represents a cohesive vision where aggressive styling meets functional performance. The combination of the extreme widebody and the renowned RE Amemiya aero creates a car that is both a visual spectacle and a potent machine.
| Modification | Primary Benefit | Potential Considerations |
|---|---|---|
| Ronin Speedworks Widebody | Accommodates wider tyres, aggressive aesthetic | Increased weight, requires extensive bodywork |
| 285mm Tyres | Enhanced grip (acceleration, braking, cornering) | Higher rolling resistance, potential for heavier steering |
| RE Amemiya Front Bumper & Spoiler | Improved cooling, aerodynamic stability | Cost, potential fitment challenges |
The owner has clearly invested a significant amount of time, effort, and resources into this project. The meticulous attention to detail in fitting the widebody, ensuring perfect panel gaps, and integrating the RE Amemiya components speaks volumes about their dedication. This RX-7 is a testament to the enduring appeal of the platform and the creativity of its owners.
Frequently Asked Questions
What is a widebody kit?
A widebody kit is a set of aftermarket body panels, typically including wider fenders, bumpers, and side skirts, designed to significantly increase the width of a vehicle. This is usually done to accommodate wider tyres and wheels for improved performance or for aesthetic purposes to create a more aggressive and muscular look.
Is RE Amemiya a reputable tuner?
Yes, RE Amemiya is a highly respected and reputable tuning company from Japan, particularly known for its expertise with Mazda's rotary engines and its distinctive, performance-oriented styling packages. They have a long history of success in motorsports.
What are the benefits of wider tyres?
Wider tyres offer a larger contact patch with the road, which can lead to improved traction for better acceleration, braking, and cornering grip. However, they can also increase rolling resistance and steering effort.
How much does a widebody kit typically cost?
The cost of widebody kits can vary significantly depending on the brand, material, and complexity. For high-quality kits like those from Ronin Speedworks, you can expect to pay anywhere from $2,000 to $10,000 or more, not including professional installation and painting, which can add substantially to the overall cost.
Is this modification reversible?
While the widebody kit itself is bolted or bonded on, the installation process often involves cutting and modifying the original fenders and body panels. Therefore, returning the car to its stock bodywork can be a complex and expensive process, often requiring replacement of the original panels.
In conclusion, this Mazda RX-7, with its imposing Ronin Speedworks widebody and refined RE Amemiya aero, represents a pinnacle of custom automotive design. It’s a car that not only pays homage to the RX-7’s legacy but also carves out its own unique identity through bold modifications and a clear focus on both form and function. The sheer scale of the transformation, particularly the integration of those 285mm tyres, makes this RX-7 a truly remarkable machine.
