Cast is suitable for smooth roads, and often affected by many potholes. The difference is explained at the bottom of the ad. Rims in the style of Juffali import, suitable for Korean import cars. Here is a breakdown of the main differences between them: 1. Manufacturing Method Cast Rims: Made by melting aluminum and pouring it into a custom mold. Forged Rims: Made by pressing a solid block of aluminum under immense mechanical pressure and high heat. 2. Weight Cast Rims: Generally heavier due to the high density of the metal within the mold. Forged Rims: Much lighter (up to 25% lighter than cast), which improves the car's acceleration and stability. 3. Hardness and Durability Cast Rims: Very suitable for normal daily driving, but may be prone to breaking or bending if exposed to a very deep pothole or a strong impact. Forged Rims: The metal structure is very cohesive thanks to the immense pressure, making them much stronger and more resistant to bending or breaking in harsh driving conditions. 4. Cost Cast Rims: Economical and affordable, and they come as standard (original) with most cars. Forged Rims: Very expensive due to the complexity and cost of the manufacturing process.
