Worn or soft factory mounts can contribute to rear-end “slop,” inconsistent traction, and delayed chassis response. By tightening the subframe interface, this kit supports better feedback, stability under load, and improved driveline response especially on lowered or track-driven setups.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable aria-label=\"Product Specifications\" role=\"table\" class=\"specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003eSPF3946K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eUPC\u003c\/th\u003e\n\u003ctd\u003e9317745039464\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePosition\u003c\/th\u003e\n\u003ctd\u003eRear Subframe Mount Bushings (Complete Set)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eSuperPro Polyurethane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eVehicle Fitment\u003c\/th\u003e\n\u003ctd\u003e2011 BMW 1 Series M Base (E82\/E88)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCountry of Origin\u003c\/th\u003e\n\u003ctd\u003eAustralia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003eLimited Lifetime\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThis part fits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2011\u003c\/strong\u003e BMW \u003cstrong\u003e1 Series M\u003c\/strong\u003e Base (E82\/E88 chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEstimated install time:\u003c\/strong\u003e 4–6 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDifficulty:\u003c\/strong\u003e Advanced (subframe removal and bushing pressing required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommendation:\u003c\/strong\u003e Professional installation strongly recommended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlignment:\u003c\/strong\u003e A professional alignment is recommended after installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv class=\"faq\"\u003e\n\u003ch4\u003eWill this make the ride harsher?\u003c\/h4\u003e\n\u003cp\u003eExpect a \u003cstrong\u003eslightly firmer feel\u003c\/strong\u003e versus stock rubber mounts.
