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. The kit includes racing camber plates and spherical upper mounts front and rear, eliminating the compliance found in factory rubber mounts for sharper turn-in response and consistent alignment under load.\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 20mm from factory height. The rear includes a dedicated height adjuster providing 1.5mm of change per full rotation, allowing fine-tuning of rake and balance without altering spring preload.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eSKU: BMU MU30S1\u003c\/li\u003e\n \u003cli\u003eÖhlins Dual Flow Valve (DFV) technology\u003c\/li\u003e\n \u003cli\u003eSingle external adjuster with 20 clicks controlling compression and rebound\u003c\/li\u003e\n \u003cli\u003eTarget ride height reduction: approximately 20mm\u003c\/li\u003e\n \u003cli\u003eSpring rates: 120 N\/mm front, 160 N\/mm rear (Swift, manufactured to Öhlins specifications)\u003c\/li\u003e\n \u003cli\u003eSpherical upper mounts included — front and rear\u003c\/li\u003e\n \u003cli\u003eFront racing camber plates with adjustable camber\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\u003eRacing camber plates with spherical bearings\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\u003eSpherical bearing upper mounts\u003c\/li\u003e\n \u003cli\u003eSpring preload adjustment\u003c\/li\u003e\n \u003cli\u003eIndependent ride height adjustment (1.5mm per rotation)\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 (E46)\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\/4328EB7D604A312977382DC134517012D10BAFF27E7644FFD0180CBD63E17A38\/50c3c11b595b460199be1a72660bab8b\/pdf\/media\/63f9b74f4a5444f9b60b6c789fdec91f\/U00250-01_1_MI_BMU_MU30S1.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\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\u003eSpherical upper mounts will transmit more noise, vibration, and harshness than factory rubber mounts — this is inherent to the design and expected for track-focused components\u003c\/li\u003e\n \u003cli\u003eThe BMW E46 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":57589533343908,"sku":"BMU MU30S1","price":6149.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0013\/9929\/1964\/files\/E46M3-OhlinsTrack_e591a001-d940-4459-a7a8-170afb6865ae.jpg?v=1792599715","url":"https:\/\/www.amtuning.ca\/products\/ohlins-e46-m3-dedicated-track-monotube-suspension-package","provider":"AM Tuning Canada","version":"1.0","type":"link"}
