Rims that are too small quickly make a vehicle appear high-legged and unstable. The new Lightweight Forged Rims ”AC3“ from AC Schnitzer, on the other hand, are truly earthy.\u003c\/p\u003e\n\u003cp\u003e-\tmachined “GESCHMIEDET” logo on the front\u003c\/p\u003e\n\u003cp\u003e-\tmachined original AC Schnitzer logo\u003c\/p\u003e\n\u003cp\u003e-\tstainless steel plate ”One of 300 LIMITED EDITION“\u003c\/p\u003e\n\u003cp\u003e-\tLimited Edition\u003c\/p\u003e\n\u003cp\u003eAC Schnitzer already gave the one-piece Lightweight Forged Rims AC3 extremely sporty genes in their design and these manifest themselves in their outer appearance: the central element is the filigree yet massive spoke matrix with its five triangular struts. The strong concave centre, to which the spokes seem to rush, underlines the uncompromisingly dynamic impression. A stainless steel plate also indicates the rarity value of each AC3 Lightweight Forged Rim: \"One of 300 LIMITED EDITION\".

In addition to the main component aluminium, the alloy also contains one percent magnesium and one percent titanium each (which ensures finer grain size). The precise composition of the material alloy has a decisive influence on the subsequent properties of the wheel.\u003c\/p\u003e\n\u003cp\u003ePure Aluminium\u003c\/p\u003e\n\u003cp\u003eApproximately 97 percent of the alloy consists of pure aluminium.
