To be 100% sure we suggest you to go to your retailer and directly check the weight of each single wheel you wish to purchase.We inform you that OZ manufactures and distributes ALLEGGERITA HTL, a series of particularly performing wheels: thanks to spamming the rim the HLT process (“High Light Technology”) permits it to get mechanical features which are similar to those of a forged wheel, by drastically increasing the resistance, thus decreasing the weight of the wheel. Each ALLEGGERITA HLT is equipped with a “lightness certificate” namely an exclusive label reporting: weight of each wheel, name of the operator having weighted it (max tolerance 2%), date of the control and TÜV homologation http://www.ozracing.no/innovation-and-safety/
