There are many different types of aftermarket rims on the market. Forged wheels offer the most advantages over other rim types, and have proven to be the best custom Porsche wheels. Forged rims can be classified into two types: forged monoblock wheels and forged 3 piece rims.
No matter what type of forged rim your custom Porsche wheels are, they all begin as high strength T6-6061 aluminum blocks. These blocks of aerospace quality aluminum are pressed inside a forging machine where high amounts of pressure compress the aluminum and form the shape of a wheel. Due to the heat and pressure caused by the forging process, tiny cracks and bubbles that can form in the metal are virtually eliminated. This also creates a dense makeup, thus requiring less metal to be used to achieve a predetermined strength. After the metal is stamped out, it is then taken to a CNC milling machine where excess metal is trimmed and the finished wheel design is carved out. After the manufacturing process the rim is later constructed and/or finished and painted.
While both types of forged rims offer performance and strength benefits, forged monoblock wheels provide the best weight and strength advantages. Forged monoblock wheels are often referred to as 1-piece rims because they are made from a single piece of forged aluminum. These custom Porsche wheels are the lightest of any forged rims because of their 1-piece construction. For Porsche owners looking to increase performance, forged monoblock wheels are recommended because their light weight and high strength reduces unsprung mass at the wheel hub, contributing to faster acceleration, better handling, improved braking, and improved fuel mileage. Forged monoblock wheels are usually the least expensive type of forged rim, however they cost more to repair due to their one-piece construction.
The other type of custom Porsche wheels that are forged are 3 piece rims. Forged 3 piece wheels are made of an inner hoop, an outer hoop, and a wheel face. Instead of being manufactured as a single unit, these pieces are forged from separate aluminum blocks. After the pieces are formed the inner and outer hoops are secured together using a Silicone RTV seal. The wheel face is then connected to the hoops by a number of perimeter bolts. The 3 piece construction of these custom Porsche wheels result in a higher overall weight, but allows for a wide range of customization. Three piece rims are the most expensive of the forged wheel types, but if they are damaged only the damaged piece needs to be replaced instead of the entire wheel.
A wide range of customization options are available to both rim types. Monoblock forged wheels and 3 piece forged rims can be ordered with any kind of finish or color scheme. Three piece rims are the only custom Porsche wheels that can be ordered in different widths and offsets to create a truly perfect fitment. Both rim types can also be made to fit aftermarket big brake kits.
