Built around Öhlins' Dual Flow Valve (DFV) technology and constructed with aluminum monotube damper bodies, this system provides exceptional control over both compression and rebound damping — allowing the suspension to respond accurately to changing road and circuit conditions while maintaining consistent tire contact across all four corners.\u003c\/p\u003e\n\n\u003cp\u003eUnlike conventional damper designs, the DFV system manages fluid flow across the full range of shaft speeds. At low shaft speeds, fluid passes through the bleed circuit for controlled, compliant damping. As shaft speed increases, flow transitions through the piston ports, and under high load or sudden impacts, the DFV opens to allow additional flow. This results in improved bump absorption, increased traction, and reduced harshness — unlocking the full dynamic potential of Audi's B9-generation sport sedan and coupe platforms.\u003c\/p\u003e\n\n\u003cp\u003eÖhlins compensates for heat-induced changes in fluid viscosity using a temperature-reactive needle bleed valve, which adjusts flow as damper temperatures rise during extended track use. This ensures consistent, predictable handling from street driving through sustained circuit sessions, with the same repeatability that Öhlins' motorsport heritage demands.\u003c\/p\u003e\n\n\u003cp\u003eRide height adjustment is handled independently from spring preload through a threaded lower mount design. This allows precise lowering without altering spring characteristics or reducing suspension travel, preserving the engineered balance of the system and the natural poise of the B9 chassis.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: AUS MU00S1\u003c\/li\u003e\n  \u003cli\u003eÖhlins Dual Flow Valve (DFV) technology\u003c\/li\u003e\n  \u003cli\u003eSingle external adjuster with 25 clicks controlling compression and rebound (1-way)\u003c\/li\u003e\n  \u003cli\u003eLowering range: approximately 10–35mm front and rear\u003c\/li\u003e\n  \u003cli\u003eSpring rates: 120 N\/mm front, 140 N\/mm rear\u003c\/li\u003e\n  \u003cli\u003eAluminum monotube damper construction\u003c\/li\u003e\n  \u003cli\u003eSeparate ride height adjustment independent of spring preload\u003c\/li\u003e\n  \u003cli\u003eRebuildable and serviceable dampers\u003c\/li\u003e\n  \u003cli\u003eDesigned for both street and track use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eFront Suspension Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum monotube damper construction\u003c\/li\u003e\n  \u003cli\u003eSpring preload adjustment\u003c\/li\u003e\n  \u003cli\u003eSeparate damper length adjustment for ride height\u003c\/li\u003e\n  \u003cli\u003eCompatible with factory top mounts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eRear Suspension Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum monotube shock absorber\u003c\/li\u003e\n  \u003cli\u003eSpring preload adjustment\u003c\/li\u003e\n  \u003cli\u003eIndependent ride height adjustment\u003c\/li\u003e\n  \u003cli\u003eCompatible with factory top mounts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eVehicle Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAudi A4 (B9)\u003c\/li\u003e\n  \u003cli\u003eAudi S4 (B9)\u003c\/li\u003e\n  \u003cli\u003eAudi A5 (B9)\u003c\/li\u003e\n  \u003cli\u003eAudi S5 (B9)\u003c\/li\u003e\n  \u003cli\u003eAudi RS4 (B9)\u003c\/li\u003e\n  \u003cli\u003eAudi RS5 (B9)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical Resources\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/www.ohlins.com\/storage\/3DD742D4B5AB566024DFA4149502E22C5D41FB7B78302995AC7D8D1941278301\/90d5f017025a460884d9e24d1561834c\/pdf\/media\/16c6197c3b2b4394b776e59539071fbf\/MI_AUS%20MU00S1_0.pdf\" target=\"_blank\"\u003eInstallation Guide\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/www.ohlins.com\/storage\/7AC688BED0B27E53064F094EF615E1B088E4D8FEA94635A5D2ECCC5FB1894053\/b31b9618ad354b438a407241ceb64a6d\/pdf\/media\/d60188c2ea574151aad35b903c54e441\/OM_07451-01_7_R_T.pdf\" target=\"_blank\"\u003eOwner's Manual\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/www.ohlins.com\/storage\/015EA1834DCE6F0EF400074576A7147844715E6849A1B1043EDE37FBE98B5A26\/91d294d68d7d4bd2acb29170ca8907cd\/pdf\/media\/1de1c85bdf7c41c8930f007ed26bbba1\/MI%20Cancellation%20kit%2035020-31.pdf\" target=\"_blank\"\u003eCancellation Kit Installation Guide (35020-31)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSuspension components are non-returnable once installed\u003c\/li\u003e\n  \u003cli\u003eVehicles equipped with factory electronic dampers (Audi Magnetic Ride) require the Öhlins cancellation kit (part no. 35020-31) to eliminate dashboard warning lights when installing this coilover system — verify your vehicle's configuration before ordering\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ohlins","offers":[{"title":"Default Title","offer_id":45710957281476,"sku":"AUS MU00S1","price":3300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0067\/6236\/4997\/products\/audi-rs4-aus-ms00-front-5b35f15c5ebdf.jpg?v=1772078665","url":"https:\/\/ind-distribution.com\/products\/ohlins-b9-a4-s4-a5-s5-rs4-rs5-coilover-suspension-road-track","provider":"IND Distribution","version":"1.0","type":"link"}
