Tuning cars refers to the process of modifying a vehicle to enhance its performance, appearance, or both. This can involve adjusting the engine, suspension, or exhaust system to improve speed, handling, and fuel efficiency. Car enthusiasts often seek to personalize their vehicles to reflect their style and preferences. Common tuning methods include installing aftermarket parts, remapping the engine's computer, and upgrading the suspension or brakes. Many tuners also focus on aesthetics, adding features like custom paint jobs, spoilers, or alloy wheels. Overall, tuning allows car owners to create a unique driving experience tailored to their needs.
