The 57TR shares the 57DR’s RAYS engineering foundation but applies a spoke geometry optimized for the thermal cycles, braking loads, and cornering forces that repeat lapping imposes on a wheel. For time attack and track day drivers who need a cast wheel with genuine circuit credentials at a price point below the forged Volk Racing TE37, the 57TR has been the reference in the Japanese circuit community since the platform was introduced.\u003c\/p\u003e\u003cp\u003eFeatures:\u003c\/p\u003e\u003cp\u003e• \u003cstrong\u003eTR Track Racing Design Brief:\u003c\/strong\u003e Spoke geometry and construction calibrated for circuit use, thermal cycles, and repeated braking loads.\u003c\/p\u003e\u003cp\u003e• \u003cstrong\u003eRAYS Cast Engineering:\u003c\/strong\u003e Alloy specification and quality standard shared across the 57-series line.\u003c\/p\u003e\u003cp\u003e• \u003cstrong\u003eTime Attack Community Reference:\u003c\/strong\u003e Circuit-proven design in the Japanese time attack and track day market.\u003c\/p\u003e\u003cp\u003e• \u003cstrong\u003eBelow-Forged Price Point:\u003c\/strong\u003e RAYS circuit engineering at cast construction pricing.\u003c\/p\u003e\u003cp\u003eRAYS’s circuit-focused cast wheel for track day and time attack builds where the 57TR’s engineering credibility and price point meet.\u003c\/p\u003e","brand":"Gram Lights","offers":[{"title":"18x7.5 +38 5x114.3 \/ Eternal Blue Pearl","offer_id":54744178458942,"sku":"584887538952XZ","price":117000.0,"currency_code":"JPY","in_stock":true},{"title":"18x7.5 +38 5x114.3 \/ Glass Black","offer_id":54744178491710,"sku":"584887538956XZ","price":117000.0,"currency_code":"JPY","in_stock":true},{"title":"18x7.5 +45 5x112 \/ Eternal Blue Pearl","offer_id":54744178524478,"sku":"584887545202XZ","price":117000.0,"currency_code":"JPY","in_stock":true},{"title":"18x7.5 +45 5x112 \/ Glass Black","offer_id":54744178557246,"sku":"584887545206XZ","price":117000.0,"currency_code":"JPY","in_stock":true},{"title":"18x7.5 +45 5x100 \/ Eternal Blue Pearl","offer_id":54744178590014,"sku":"584887545962XZ","price":117000.0,"currency_code":"JPY","in_stock":true},{"title":"18x7.5 +45 5x100 \/ Glass Black","offer_id":54744178622782,"sku":"584887545966XZ","price":117000.0,"currency_code":"JPY","in_stock":true},{"title":"18x7.5 +48 5x114.3 \/ Eternal Blue Pearl","offer_id":54744178655550,"sku":"584887548952XZ","price":117000.0,"currency_code":"JPY","in_stock":true},{"title":"18x7.5 +48 5x114.3 \/ Glass Black","offer_id":54744178688318,"sku":"584887548956XZ","price":117000.0,"currency_code":"JPY","in_stock":true},{"title":"18x8.0 +45 5x112 \/ Eternal Blue Pearl","offer_id":54744178721086,"sku":"584888045202XZ","price":119000.0,"currency_code":"JPY","in_stock":true},{"title":"18x8.0 +45 5x112 \/ Glass Black","offer_id":54744178753854,"sku":"584888045206XZ","price":119000.0,"currency_code":"JPY","in_stock":true},{"title":"18x8.0 +45 5x100 \/ Eternal Blue Pearl","offer_id":54744178786622,"sku":"584888045962XZ","price":119000.0,"currency_code":"JPY","in_stock":true},{"title":"18x8.0 +45 5x100 \/ Glass Black","offer_id":54744178819390,"sku":"584888045966XZ","price":119000.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/8542\/8286\/files\/0_7a0027ed-df33-4558-a121-0a84d99ba466.jpg?v=1792900183","url":"https:\/\/jdm247.com\/products\/gram-lights-57tr-wheel","provider":"JDM 24\/7","version":"1.0","type":"link"}
