Set of O.Z wheels 800$Great set of wheels.The High Light Technology (HLT) process used in the manufacturing of O.Z. Racing's Alleggerita HLT and Botticelli HLT wheels, for example, uses rollers to compress and elongate the material along the barrel of a low-pressure cast aluminum wheel to obtain the desired profile. This process, which is directly derived from O.Z.'s experience in F1, produces wheels that are extremely light and strong.
The flow forming process and the HLT technologies combine to create mechanical characteristics similar to those of a forged wheel. This permits a dramatic reduction in wheel weight while enhancing structural rigidity vs. a standard cast wheel.
