What does JDM mean?

[JuliannaDella]

JDM stands for Japanese-Domestic-Market, referring to the Japanese domestic market, also known as Japanese car culture. Some car enthusiasts modify their vehicles to achieve a JDM style by replacing the original wheels, brakes, exhaust systems, and body kits with Japanese-style components. In summary, JDM represents a Japanese car modification culture. When modifying a car, the focus is typically on the powertrain, brakes, suspension, and exterior. Below are the specific details: 1. Powertrain: Modifications mainly involve the engine, such as reprogramming the ECU to enhance engine performance, replacing spark plugs to improve ignition capability, or installing high-flow air filters to boost intake efficiency. 2. Brakes: Modifications primarily target the brake pads and calipers, commonly configured as six-piston front and four-piston rear, or four-piston front and two-piston rear. 3. Suspension: Modifications focus on the wheels and tires to enhance grip and acceleration. 4. Exterior: Modifications include installing body kits and spoilers.
