{"product_id":"gs1r-1-piece-monoblock-wheel","title":"GS1R 1-Piece Monoblock Wheel","description":"The Forgeline GS1R is a one-piece monoblock wheel engineered for professional racing, specifically designed for teams competing in the IMSA Continental Tire SportsCar Challenge Grand Sport (GS) series. It merges advanced wheel technology with a motorsport-inspired design to achieve lightweight performance and superior deflection stiffness.\n\nConstructed from a single forging of 6061-T6 aluminum, the GS1R features I-beamed spoke technology and a chamfered outer lip for easier handling. It is engineered for endurance racing with a load rating of over 2100 lb. for street tires. Significant material is machined from the center to reduce weight and improve access to lug nuts, making wheel changes faster. Compared to the GA1R street wheel, the GS1R can be up to a pound lighter per wheel, depending on size and offset.\n\nCustomization is a key aspect of Forgeline wheels, with the GS1R being made-to-order in the USA. This allows for precise matching to vehicle specifications and intended applications, including custom sizes, lug patterns, and backspace\/offsets. Optional Open Lug Center Caps are available but require special machining for a proper fit, which must be specified at the time of order.","brand":"Forgeline","offers":[{"title":"Default Title","offer_id":52688424436024,"sku":"WH-SK-GS1R-18","price":1695.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663175504.webp?v=1784889973","url":"https:\/\/store.motormia.co\/products\/gs1r-1-piece-monoblock-wheel","provider":"MOTORMIA","version":"1.0","type":"link"}
