How to Modify a Subaru for JDM Style

Subaru cars have gained a wide following in the car enthusiasts’ world. They have become popular not only because of their performance but also their sleek and stylish design. Among its many modified styles, one that seems to be on the rise is the JDM (Japanese Domestic Market) style. In this guide, we will delve into the different modifications that can be done to achieve a JDM style in your Subaru.

Exterior Modifications

The exterior of a JDM car is crucial to its overall look and appeal. Some of the modifications commonly made to the exterior of a Subaru to achieve a JDM style include body kits and spoilers. Body kits like the Chargespeed, Varis, and STI are popular among JDM enthusiasts. These body kits enhance the car’s design and its aerodynamics, which in turn improves its stability and performance. The spoilers, on the other hand, add a more aggressive, sporty look to the car. They come in different sizes and shapes, from limited-edition options to more cost-effective ones.

Another popular modification to the exterior of a JDM car is the use of JDM decals. These can come in the form of a Japanese Kanji script or a JDM emblem. They add a unique and authentic touch that accentuates the car’s JDM feel.

Interior Modifications

The interior of a car is where most of the driver’s time is spent and is just as important as the exterior. Changes to the interior of a Subaru can include the installation of racing seats and a steering wheel. The seats are designed to provide maximum support and comfort, and come in different styles to match the interior design. The steering wheels, on the other hand, typically feature a smaller diameter to provide better feedback and control.

Other interior modifications that can be done to achieve a JDM style include the use of gauge clusters and custom shift knobs. Gauge clusters inform the driver of the car’s vital information, such as the speed, temperature, and fuel levels. The custom shift knobs, on the other hand, add a personal touch to the car’s interior design.

Performance Modifications

The performance of a car is the most notable aspect of a JDM build. It is the performance modifications that make the car different from a stock car. Engine tuning, suspension upgrades, and exhaust systems are just a few of the common ways that JDM Subarus are modified for improved performance.

Engine tuning involves tweaking and optimizing the car’s engine components such as the air intake, fuel injection, and exhaust system. These modifications increase the engine’s performance output, which results in faster acceleration and higher top speeds. Suspension upgrades, on the other hand, improve the car’s handling performance by lowering the center of gravity and making the car more stable on the road.

Exhaust systems are modified to make the car’s engine breathe better and sound better too. A JDM-style exhaust system provides a deeper, throatier tone, making the car sound more aggressive and sporty. Some of the popular brands for JDM-style exhaust systems include Apexi, HKS, and Borla.

In conclusion, achieving a JDM style requires an understanding of what makes a JDM car unique. The modifications discussed here are just a few of the ways that one can achieve a JDM style in their Subaru. It is essential to keep in mind that any and all modifications should be done by a knowledgeable and qualified mechanic to ensure safety and optimal performance.
