Built around Öhlins' Dual Flow Valve (DFV) technology, this system provides exceptional control over both compression and rebound damping, allowing the suspension to respond accurately to the demands of both spirited road driving and dedicated circuit use while maintaining consistent tire contact throughout.\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 — building on the already strong chassis foundation shared between the Z4 and GR Supra 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, providing the repeatability that drivers and instructors rely on when pushing these platforms at speed.\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 handling character of the G29 and A90 platforms.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: TOS 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: 0–25mm front, 0–25mm rear\u003c\/li\u003e\n  \u003cli\u003eSpring rates: 90 N\/mm front, 160 N\/mm rear\u003c\/li\u003e\n  \u003cli\u003eSeparate ride height adjustment independent of spring preload\u003c\/li\u003e\n  \u003cli\u003eMonotube damper construction\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\u003eMcPherson strut design with inverted monotube 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\u003eBMW Z4 (G29)\u003c\/li\u003e\n  \u003cli\u003eToyota GR Supra (A90)\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\/9FAC6D0B27AB41707C875163C506FDCB61AC9C42B16210DD4420160FB96D6A26\/f490b434ce34420ea57d927e62854685\/pdf\/media\/e3c19e794787444fa4cf62075bd15dcd\/MI_TOSMU00S1_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\/D0660544A17472C616F7C045EAD1ACAF19CC005EF56460A16215C2A6BF562622\/a624e6f8652f4f4ba09f9e496d6c5c3a\/pdf\/media\/b3a0cab39caf4e5ab110a1b18b079860\/MI%20Cancellation%20kit%2035020-30.pdf\" target=\"_blank\"\u003eCancellation Kit Installation Guide (35020-30)\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 require the Öhlins cancellation kit (part no. 35020-30) 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":45704926167236,"sku":"TOS MU00S1","price":3400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0067\/6236\/4997\/files\/BMS-TOSMU00-1.webp?v=1772078651","url":"https:\/\/ind-distribution.com\/products\/ohlins-g29-z4-a9x-gr-supra-coilover-suspension-road-track","provider":"IND Distribution","version":"1.0","type":"link"}
