The reviewer found them most useful for classic and late model GM cars listed in the fitment, where the main reason to buy is the precise hubcentric fit and durable T6 billet aluminum construction that keeps wheels centered without adding excessive unsprung weight.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Designed to match 5x4.75 bolt patterns for many GM models, offering a direct mechanical match when fitment checks out.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e The 1in (25mm) spacer provides consistent wheel offset gain that helps clear brakes or suspension components and gives a more aggressive stance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Machined from T6 billet aluminum for a balance of strength and low weight compared with steel alternatives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware:\u003c\/strong\u003e Preinstalled hardened 10.9 grade bolts provide secure clamping and reduce the number of loose parts during installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHubcentric design:\u003c\/strong\u003e The 70.5mm inner diameter centers the wheel on the spacer, improving wheel alignment to the hub and reducing vibration risk.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis product is best for owners of compatible GM vehicles who need a modest, hubcentric increase in track width, including owners of S15, Jimmy, Corvette and older Buick and Pontiac models listed in the fitment.
