Each set is engineered specifically for this Z chassis, so drop, spring rate and factory damper tune stay in balance — the car sits where you want it and still drives like a daily.\u003c\/p\u003e\u003cp\u003eRacing Studio-R built its first suspension in Osaka in 1972 and has been refining the Down Sus spring for more than fifty years. Each set is progressive-rate, cold-wound and heat-treated in-house in Japan, then matched to the factory shock valving and ride-height target of the specific chassis it bolts onto. Backed by RS-R’s 3-year \/ 50,000 km fatigue warranty.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eProgressive-rate coil tuned to the factory damper\u003c\/li\u003e\n\u003cli\u003eVehicle-specific drop and rate — no universal cuts\u003c\/li\u003e\n\u003cli\u003eCold-wound from high-grade SAE alloy steel\u003c\/li\u003e\n\u003cli\u003ePowder-coated for long-term corrosion resistance\u003c\/li\u003e\n\u003cli\u003e3-year \/ 50,000 km RS-R spring-fatigue warranty\u003c\/li\u003e\n\u003cli\u003eMade in Osaka, Japan\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch5\u003eSpecifications\u003c\/h5\u003e\u003ctable class=\"table table-striped table-primary\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eN135D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Name\u003c\/td\u003e\n\u003ctd\u003eRS-R Down Sus Lowering Springs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVehicle\u003c\/td\u003e\n\u003ctd\u003e2023+ Nissan Z\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChassis Code\u003c\/td\u003e\n\u003ctd\u003eRZ34\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRide-Height Adjustable\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Type\u003c\/td\u003e\n\u003ctd\u003eProgressive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproximate Drop - Front\u003c\/td\u003e\n\u003ctd\u003e-15mm to -20mm (-0.6in to -0.8in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproximate Drop - Rear\u003c\/td\u003e\n\u003ctd\u003e-25mm to -30mm (-1.0in to -1.2in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate - Front\u003c\/td\u003e\n\u003ctd\u003e10.20 Kg\/mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate - Rear\u003c\/td\u003e\n\u003ctd\u003e8.13 Kg\/mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e3 Years \/ 50,000 km\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch5\u003eVehicle Fitment\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003e2023 Nissan Z\u003c\/li\u003e\n\u003cli\u003e2024 Nissan Z\u003c\/li\u003e\n\u003cli\u003e2025 Nissan Z\u003c\/li\u003e\n\u003cli\u003e2026 Nissan Z\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RS-R","offers":[{"title":"Default Title","offer_id":44252464382012,"sku":"N135D","price":369.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0000\/2183\/products\/rs-r-down-sus-lowering-springs-2014-2015-lexus-is250-gse30-gse31-t195d-1194428525.jpg?v=1768107701","url":"https:\/\/www.springrates.com\/products\/rs-r-down-sus-lowering-springs-2023-nissan-z","provider":"SPRINGRATES®","version":"1.0","type":"link"}
