Running a wider 20x9 front and 21x12 rear, this fitment delivers a more aggressive stance than the standard setup while keeping the clean flush look the C8 deserves. Its high-concavity forged face and multi-spoke architecture fill the C8 arch perfectly at every angle. Crafted from precision-forged 6061-T6 aerospace-grade aluminum, the GEM GZR is stronger and lighter than any cast or flow-forged alternative, engineered to the 5x120.65 bolt pattern of the C8 Corvette with no modifications required.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront Wheels:\u003c\/strong\u003e 20x9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Wheels:\u003c\/strong\u003e 21x12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Pattern:\u003c\/strong\u003e 5x120.65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront Offset:\u003c\/strong\u003e 35MM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Offset:\u003c\/strong\u003e 52MM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e GEM GZR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Forged Monoblock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061-T6 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e See Available Finishes below\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Caps:\u003c\/strong\u003e Accepts OEM Corvette Caps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Stems:\u003c\/strong\u003e Not Included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e Set of 4 Wheels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuild Time:\u003c\/strong\u003e Approx 5-6 Weeks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFull Forged Construction — Stronger and Lighter Than Cast or Flow-Formed\u003c\/li\u003e\n\u003cli\u003eForged 6061-T6 Aerospace-Grade Aluminum\u003c\/li\u003e\n\u003cli\u003eFender-Flush Fitment Engineered for the C8 Z51 Platform\u003c\/li\u003e\n\u003cli\u003eAccepts OEM Corvette Center Caps\u003c\/li\u003e\n\u003cli\u003eStock TPMS Compatible\u003c\/li\u003e\n\u003cli\u003eBig Brake Kit Clearance\u003c\/li\u003e\n\u003cli\u003eMaximum Concavity Profile\u003c\/li\u003e\n\u003cli\u003eLifetime Structural Warranty\u003c\/li\u003e\n\u003cli\u003eMessage Us for a Free Custom Render of Your Vehicle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAvailable Finishes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGloss Black\u003c\/li\u003e\n\u003cli\u003eSatin Black\u003c\/li\u003e\n\u003cli\u003eSilver\u003c\/li\u003e\n\u003cli\u003eGunmetal\u003c\/li\u003e\n\u003cli\u003eCarbon Flash\u003c\/li\u003e\n\u003cli\u003eBrushed Aluminum\u003c\/li\u003e\n\u003cli\u003eBrushed Titanium\u003c\/li\u003e\n\u003cli\u003eBrushed Champagne\u003c\/li\u003e\n\u003cli\u003eSatin Bronze\u003c\/li\u003e\n\u003cli\u003eChrome\u003c\/li\u003e\n\u003cli\u003eDark Chrome\u003c\/li\u003e\n\u003cli\u003eGloss Black \/ Machine Face\u003c\/li\u003e\n\u003cli\u003eChrome Gold\u003c\/li\u003e\n\u003cli\u003eBrushed Bronze\u003c\/li\u003e\n\u003cli\u003eSatin White\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eChrome, Chrome Gold, Dark Chrome, Satin Bronze, Brushed Bronze, and Brushed finishes may require an additional 1-2 weeks beyond standard build time.\u003c\/p\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGuaranteed Fitment:\u003c\/strong\u003e Chevrolet Corvette C8 Z51\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNo modifications required.
