Forged or Cast Aluminum Whats the Difference?

Forged or Cast Aluminum whats the difference? That's a question you may be asking yourself. "Forged" and "Cast" refer to the type of manufacturing process and they could not be more different. Forging refers to cold working the metal from one solid piece of billet aluminum. Generally this done by forcing the aluminum material between forging dies under extreme high pressure. This changes the molecular grain structure of the aluminum packing them tightly together. Once the forging process is completed the strength of the material is increased. After Forging a blank is placed in a CNC cutting machine and the wheel shape is cut out in what ever shape the manufacture has programmed. This is a time consuming process but it yields the strongest one piece design and usually the lightest wheel you can buy. After machining any finish can be applied.
Cast wheels are just like the name implies. A sand casting negative of the wheel is made and molten aluminum is either gravity fed or force fed into the mold. This is an art in itself to do right. The advantage to casting under pressure is that it forces more material into the cast making the wheel stronger. Cast wheels then are finished in any popular finish like chrome, paint or powder coat. Cast wheels are generally of less strength from its cousin forged but is an economical solution. Cast wheels will have more intricate detail from forged allowing a greater selection of designs.

How to Measure C5 Corvette Wheels Offset

Example

Rim Width / 2 = Centerline
Centerline + Offset + Rim Lip = Backspacing

8" wide rims / 2 = 4" Centerline
4" centerline + 0.63" Offset + 0.25" Lip = 4.88" Backspacing

Offset

Offset is the distance from the rim's mounting surface to the centerline. Positive offset means the mounting surface is moved towards the outside (away from the center of the car) of the rim. Negative offset is the opposite.

Backspacing

Backspacing is the inside depth of the rim. It can easily be measured by putting a yardstick across the backside of the rim, and measuring the distance between the mounting surface and the yardstick.

C5 Corvette wheels backspacing can also be calculated, as shown above. Don't forget to add for the rim's lip and tire bulging past the rim (Roughly about .25"). Per our Example the 16x8" 0mm offset front rims would have 4.25" of backspacing. The positive 16mm rear rims (16mm/25.4 = 0.63") have about 4.9" of backspacing
