{"product_id":"ohlins-e9x-m3-dedicated-track-monotube-suspension-package","title":"Ohlins E9X M3 Dedicated Track Monotube Suspension Package","description":"\u003cp\u003eThe Öhlins Dedicated Track Monotube Suspension Package for the BMW M3 (E9X) is a pre-tuned, bolt-on track suspension system built for drivers who demand circuit-ready performance straight from the box. Developed using Öhlins' Dual Flow Valve (DFV) technology and paired with Swift springs manufactured to Öhlins specifications, this package delivers precise, repeatable handling at the limit. Each application is shake-rig developed and track validated, with specific spring rates, damper click settings, and ride height specifications established to suit the chassis — no guesswork required at the track.\u003c\/p\u003e\n\n\u003cp\u003eThe DFV system allows fluid to flow efficiently in both compression and rebound phases. At low shaft speeds, fluid passes through the bleed circuit for controlled 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 — critical for maintaining speed and consistency through extended track sessions.\u003c\/p\u003e\n\n\u003cp\u003eÖhlins' temperature-reactive needle bleed valve compensates for changes in fluid viscosity as damper temperatures rise during sustained track use. This ensures predictable handling and repeatable lap times, even in the most demanding conditions.\u003c\/p\u003e\n\n\u003cp\u003eRide height is set to a target reduction of approximately 15mm front and 10mm rear from factory height, providing an optimal platform for track alignment without excessive lowering that could compromise suspension travel.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eSKU: BMU MU40S1\u003c\/li\u003e\n \u003cli\u003eÖhlins Dual Flow Valve (DFV) technology\u003c\/li\u003e\n \u003cli\u003eSingle external adjuster controlling compression and rebound; 0–7 clicks recommended for track use\u003c\/li\u003e\n \u003cli\u003eTarget ride height reduction: approximately 15mm front, 10mm rear\u003c\/li\u003e\n \u003cli\u003eSpring rates: 120 N\/mm front, 180 N\/mm rear (Swift, manufactured to Öhlins specifications)\u003c\/li\u003e\n \u003cli\u003eMonotube damper construction\u003c\/li\u003e\n \u003cli\u003eRebuildable and serviceable dampers\u003c\/li\u003e\n \u003cli\u003ePre-tuned for dedicated 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\u003eHeight adjustable via lower perch\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\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eVehicle Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eBMW M3 (E90)\u003c\/li\u003e\n \u003cli\u003eBMW M3 (E92 \/ E93)\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\/348A4F416A1BD095D59CBF269D8C8E6800223A7106749C7D20F5FD8F0B49371E\/89db96b89663437b9a932fea5b16c68e\/pdf\/media\/057032e5ceaf49a0a6b9d4268f48dbd5\/U00250-02_1_MI_BMU_MU40S1.pdf\" target=\"_blank\"\u003eInstallation Guide\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\u003eThe BMW E9X M3 was not equipped with factory electronic dampers — no cancellation kit is required\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ohlins","offers":[{"title":"Default Title","offer_id":53847823581348,"sku":"BMU MU40S1","price":6149.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0013\/9929\/1964\/files\/E46M3-OhlinsTrack.jpg?v=1791304596","url":"https:\/\/www.amtuning.ca\/products\/ohlins-e9x-m3-dedicated-track-monotube-suspension-package","provider":"AM Tuning Canada","version":"1.0","type":"link"}
