What does Offset mean?
Offset is the distance between the hub mounting face at the back of the wheel and the wheel’s centraline.
Offset is usually stamped or engraved into the wheel and is measured in millimetres of ‘ET’ [ET is the short form of the German word 'Einpresstiefe' which literally translates as 'insertion depth'] (more…)

Forging uses intense heat and pressure to transform a [solid} slug of alloy material into the final shape of a wheel. Forged aluminum is stronger than cast aluminum, yet less material is needed to produce the same "cast alloy wheel", which results in a lighter product. Because of the basic limitations inherent in forging, most forged wheels are two or three piece units. In two-piece construction, a centre is forged and welded or bolted into a spun or stamped outer rim. In a three-piece wheel, the centre is bolted to an inner and an outer rim half. This stands as an advantage of being easily customizable for a variety of widths and offsets.

What is Alloy Wheel?
The term alloy wheels is usually given to wheels ‘cast’ from a mixture of aluminum which is light weight and great at dissipating heat and small amounts of more rigid metals whose presence in the ‘mix’ provides rigidity and helps prevent cracks propagating.
Alloy metals provide superior strength and dramatic weight reductions over ferrous metals such as steel, and as such they represent the ideal material from which to create a high performance wheel. In fact, today it is hard to imagine a world class racing car or high performance road vehicle that doesn’t utilize the benefits of alloy wheels.
