Gravity Casting is the simplest (and cheapest) form of wheel manufacturing. The process involves pouring molten alloy directly into the wheel mold, using only theforce of gravity to push the alloy into the mold. This creates the least dense metal. Gravity Cast alloy must therefore be thicker and heavier than metal used in other manufacturing methods in order to have enough strength to be used safely for wheelApplicable Models:Volkswagen, Audi, Mercedes-Benz, Honda, Toyota, Hyundai, Kia, Mazda, Nissan
