A Comprehensive Guide to Cool Kit Automobiles and Body Kits
The automotive world is divided into two groups: those who see a car as a mere utility for transportation, and those who see it as a blank canvas for self-expression. For the latter, the stock appearance of a vehicle is simply a starting point. Kit automobiles and aftermarket body kits represent the pinnacle of automotive customization, allowing enthusiasts to redefine the aesthetics, aerodynamics, and even the fundamental identity of their machines.
Whether you are looking to turn a modest sedan into a track-ready beast or dreaming of building a classic supercar replica from the ground up, understanding the nuances of body kits and kit cars is essential. This guide explores the evolution, types, and practical considerations of these “cool kits” that continue to fascinate the global car culture.
Understanding the Difference: Body Kits vs. Kit Cars
Before diving into the technical details, it is important to distinguish between these two popular customization paths. While they both involve altering a vehicle’s exterior, their scope and complexity differ significantly.
What is a Body Kit?
A body kit is a collection of exterior modifications typically composed of bumpers, side skirts, spoilers, and hoods. These components are designed to replace or be added to the existing bodywork of a mass-produced vehicle. The goal is usually twofold: to improve the visual stance of the car and, in many cases, to enhance its aerodynamic properties by increasing downforce or reducing drag.
What is a Kit Automobile?
A kit automobile, or “component car,” is a much more ambitious project. Instead of modifying an existing car, you are essentially building one. These kits usually come as a set of parts—chassis, body panels, and interior components—that the owner assembles. Often, these kits utilize a “donor car” for the engine and drivetrain, such as using a Mazda Miata or a VW Beetle as the mechanical backbone for a vintage roadster replica.
Popular Types of Body Kits and Their Functions
Not all body kits are created equal. Depending on your goals—whether they are purely aesthetic or performance-oriented—the materials and designs you choose will vary.
Ground Effects and Lip Kits
These are the most common modifications for daily drivers. A “lip” is a small extension attached to the bottom of the front bumper. When combined with side skirts and a rear valence, it creates the illusion that the car is lower to the ground without the need for extreme suspension changes.
Wide-Body Kits
Popularized by brands like Liberty Walk and Rocket Bunny, wide-body kits involve extending the fenders to accommodate wider wheels and tires. This gives the vehicle a muscular, aggressive “planted” look. Installation often requires cutting the original metal fenders, making it a permanent and bold commitment to the car’s transformation.
Full Aerodynamic Conversions
For track enthusiasts, body kits serve a functional purpose. Functional rear wings, front splitters, and rear diffusers are designed to manage airflow. At high speeds, these components work together to “suck” the car toward the pavement, providing significantly more grip during high-speed cornering.
Materials Matter: From Fiberglass to Carbon Fiber
The “cool factor” of a kit is often determined by the material used in its construction. Each material offers a different balance of weight, durability, and price.
- Fiberglass (FRP): The most common and affordable material. It is lightweight and easy to manufacture, but it is brittle. If you hit a curb, fiberglass is likely to crack rather than flex.
- Polyurethane: Preferred for daily drivers. This material is flexible and “rubber-like,” meaning it can withstand minor bumps and scrapes without shattering. However, it is heavier than fiberglass and can be harder to paint.
- Carbon Fiber: The gold standard of the automotive world. It is incredibly strong and ultra-lightweight. Most enthusiasts leave carbon fiber unpainted to show off the intricate weave pattern, which has become a symbol of high-performance luxury.
The Challenges of the “Build-It-Yourself” Journey
While the idea of building a kit car or installing a wide-body kit sounds exciting, it requires a realistic assessment of your skills and resources.
Fitment and Prep Work
Contrary to what many “bolt-on” advertisements suggest, aftermarket parts rarely fit perfectly out of the box. They often require sanding, trimming, and filling to achieve seamless gaps. This “prep work” is where the quality of the final build is truly determined.
Legal and Insurance Considerations
Modifying a vehicle can have legal implications. Some body kits may cover up essential safety markers or change the height of the headlights beyond legal limits. Furthermore, you must inform your insurance provider about these modifications. Failure to do so could result in a denied claim if the vehicle is involved in an accident.
The Future of Customization: 3D Printing and Modular Kits
The industry is currently undergoing a revolution thanks to 3D printing technology. Enthusiasts are now able to design one-off components on their computers and print them in durable plastics or even metal. This DIY digital approach is lowering the barrier to entry, allowing for “modular” kits where owners can swap out different wing designs or bumper inserts depending on their mood or the specific event they are attending.
Conclusion
Cool kit automobiles and body kits represent the ultimate intersection of art and engineering. They allow owners to break away from the monotony of factory designs and create something truly unique. While the process requires a significant investment of time, money, and patience, the result is a machine that reflects the personality and passion of its creator. Whether you are aiming for the sleek lines of a carbon fiber aerodynamic package or the rugged charm of a hand-built kit car, the journey of transformation is just as rewarding as the final drive.
