I.D. Race Springs are made with extremely high tensile strength wire alloy which allows the use of a thinner wire. Manufactured using advanced materials and precision technology in Germany, H\u0026amp;R 2.50? I.D. Race Springs are crafted from special lightweight (hf) 54SiCr6 spring steel. For any given spring rate, they are on average 15% lighter and have 10% more travel than competitors? springs. Main springs range from 6? to 18? in length and are available in a wide selection of spring rates.  TENDER SPRINGS: H\u0026amp;R 2.50? I.D. Tender Springs are made of trapezoidal (flat rather than round) spring wire and have a low block height for maximum travel. These springs are designed for demanding motorsport environments, and like all H\u0026amp;R springs, have been pre-blocked at the factory so they will never set or sag. The H\u0026amp;R 60mm I.D. Race Spring line is crafted from special lightweight (hf) 54SiCr6 spring steel and is the most comprehensive 60mm I.D. Race Program in the U.S. If you own a Porsche GT3 or another Euro spec car, our range of 60mm I.D. Race Springs has you covered. With hundreds of main springs and tender springs available, H\u0026amp;R has the lengths and rates necessary for optimal tuning and setup. The H\u0026amp;R complete line of 60mm I.D. main springs range from 80mm to 300mm (25.4mm = 1 inch) in length and 25 N to 700 N (N\/mm x 5.709 = pounds\/inch) spring rates.\u003cbr\u003e\u003cbr\u003eThis Part Fits:\u003cp\u003e\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2018-2019\u003c\/td\u003e\n\u003ctd\u003ePorsche\u003c\/td\u003e\n\u003ctd\u003e911\u003c\/td\u003e\n\u003ctd\u003eGT3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"H\u0026R","offers":[{"title":"Default Title","offer_id":44910906704058,"sku":"HRS54090","price":769.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0562\/0855\/6218\/files\/3e3bb8c0-465c-460a-99a1-a6058591a878-800.jpg?v=1763360582","url":"https:\/\/performancemods.com\/products\/h-r-17-19-porsche-911-991-gt3-rs-id-race-spring-1","provider":"PERFORMANCE MODS","version":"1.0","type":"link"}
