Yokohama’s flagship forged multi-spoke wheel with direct motorsport heritage from Super GT and Japanese time attack competition. Approximately 6 lbs per wheel — exceptional weight for an 18×9.5 in any construction method. 24 lbs (set of 4).

Advan Racing sits at the top tier of the Japanese wheel market alongside Rays Volk Racing, and the RZIII is their premier multi-spoke competition design:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotorsport pedigree:\u003c\/strong\u003e The RZ series has been used in Super GT, JGTC, and Japanese national-level time attack competition across multiple generations. The RZIII carries the engineering evolution of that competition program into the current generation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForged construction:\u003c\/strong\u003e The RZIII uses a flow-forming forging process — the wheel is forged from a billet aluminium disc and then spun\/flow-formed to final wheel width under heat and pressure. This aligns the aluminium grain structure for high strength and allows very thin spoke and barrel cross-sections that would not be achievable in casting. At approximately 6 lbs for an 18×9.5, the RZIII demonstrates the weight efficiency that only forging can achieve at this diameter and width.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in Japan:\u003c\/strong\u003e Advan Racing wheels are manufactured in Japan, consistent with their OEM motorsport supply chain quality standards.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e18×9.5 at +35 — Fitment\u003c\/h3\u003e\n\u003cp\u003eThe +35 offset on an 18×9.5 is a moderate fitment specification — appropriate for stock-arch and lightly modified 5×114.3 vehicles:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e350Z \/ 370Z:\u003c\/strong\u003e The Z33 and Z34 platforms have generous rear arch clearance. 18×9.5 +35 provides a clean, slightly aggressive fitment without requiring arch modification on most builds.
