Designed as a street-and-track coilover that delivers performance dampening control without sacrificing daily-driver comfort.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eAdjustable coilovers let you tune ride height and damping to the way you actually drive. 32 clicks of damping adjustment cover the range from a comfortable street setting to a stiff track setting, which means one set of coilovers can handle daily commuting and weekend track days without compromise. The 8k front \/ 10k rear spring rates are tuned for the E46 chassis to give predictable handling on a lowered car without crashing through bumps.\u003c\/p\u003e\n\n\u003cp\u003eFront pillowball upper mounts give precise steering response and let you dial in camber for more aggressive alignment setups. Japanese-sourced bearings on critical wear points improve longevity over generic budget coilovers.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Note: Non-True-Type Rear\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThese coilovers utilize an OE-style spring and bucket setup in the rear, not a true-type coilover.\u003c\/strong\u003e The rear consists of separate springs and shocks that bolt to the factory spring perch locations, rather than an integrated coilover unit with the spring on the damper. This is normal for E46 platform coilovers and means installation in the rear is more like a spring-and-shock swap than a coilover swap.\u003c\/p\u003e\n\n\u003ch3\u003eSpring Rates\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFront: 8k (8 kg\/mm)\u003c\/li\u003e\n\u003cli\u003eRear: 10k (10 kg\/mm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW E46 (all variants - 323, 325, 328, 330)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e32-way adjustable damping\u003c\/li\u003e\n\u003cli\u003eFront pillowball upper mounts (precise feel, camber adjustability)\u003c\/li\u003e\n\u003cli\u003eJapanese-sourced bearings on critical wear points\u003c\/li\u003e\n\u003cli\u003e8k front \/ 10k rear spring rates tuned for E46\u003c\/li\u003e\n\u003cli\u003eComfortable street ride with track-capable performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2x Front coilover assembly (full coilover with pillowball mount)\u003c\/li\u003e\n\u003cli\u003e2x Rear springs\u003c\/li\u003e\n\u003cli\u003e2x Rear shocks\u003c\/li\u003e\n\u003cli\u003e1x Spanner wrench set\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e ISR Performance\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e IS-PRO-E46\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Adjustable Coilovers (Pro Series)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e BMW E46 (all variants)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eFront Configuration:\u003c\/strong\u003e True-type coilover (spring on damper)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eRear Configuration:\u003c\/strong\u003e Non-true-type (OE spring and bucket style - separate spring and shock)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eDamping Adjustment:\u003c\/strong\u003e 32-way\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSpring Rate Front:\u003c\/strong\u003e 8k (8 kg\/mm)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSpring Rate Rear:\u003c\/strong\u003e 10k (10 kg\/mm)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eFront Upper Mount:\u003c\/strong\u003e Pillowball\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBearings:\u003c\/strong\u003e Japanese-sourced\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e Street, spirited driving, and track use\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSold:\u003c\/strong\u003e Complete 4-corner kit with spanner wrenches\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eLegality:\u003c\/strong\u003e Off-road and competition use only\u003c\/p\u003e","brand":"ISR Performance","offers":[{"title":"Default Title","offer_id":45957127897285,"sku":"IS-PRO-E46","price":1094.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/2718\/9701\/files\/E461__23267.1734723757.1280.1280__23961.1734724068.500.659.jpg?v=1773346527","url":"https:\/\/www.isrcompetition.com\/products\/isr-performance-pro-series-coilovers-bmw-e46","provider":"ISR Competition","version":"1.0","type":"link"}
