These mounts are redesigned with performance in mind and manufactured from high-durometer rubber for increased performance and durability without sacrificing comfort. Density Line Mounts are void-free and fluid-free, eliminating the slop associated with the factory mounts.\u003c\/p\u003e\n\u003cp\u003e034Motorsport Density Line Transmission Mounts are manufactured from a 60 Durometer or 70 Durometer, void-free and fluid-free construction, which is a significant upgrade from the fluid-filled rubber used in stock BMW E9X M3 transmission mounts. The tail shaft of the transmission compresses and pulls up on the mounts, meaning the mount materials should be able to withstand both forces. In addition to these two forces, there are shear-twisting forces within the transmission mount assembly. Given that Polyurethane cannot withstand these forces reliably, it is not a long-term viable material for an upgrade in this location. Rubber is the ideal material for this transmission mount upgrade, as it can withstand stress under tension, compression, and shear.\u003c\/p\u003e\n\u003cp\u003eThe result is greatly reduced drivetrain slop and crisper shifting, with little to no increase in noise, vibration, or harshness (NVH) inside the cabin. The solid-rubber, void-free design eliminates the risk of collapse, a common issue with factory mounts. These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich Durometer Should You Choose — 60 vs. 70?\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable cellspacing=\"0\" cellpadding=\"2px\"\u003e\n\u003ctbody class=\"fitmentGuide\"\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eStreet Density (60D)\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eTrack Density (70D)\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBest For\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDaily \u0026amp; Spirited Driving\u003c\/td\u003e\n\u003ctd\u003eAggressive Street \u0026amp; Track Driving\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDrivetrain Control\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eReduced slop vs. factory\u003c\/td\u003e\n\u003ctd\u003eFurther reduced for max control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShift Feel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCrisper, consistent\u003c\/td\u003e\n\u003ctd\u003eMost direct\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNVH \/ Comfort\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOE-like, next to no NVH change\u003c\/td\u003e\n\u003ctd\u003eModerate vibrations \u0026amp; transmission whine audible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eStreet Density Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufactured from 60 Durometer Rubber with Void-Free Construction\u003c\/li\u003e\n\u003cli\u003eReduced Drivetrain Slop\u003c\/li\u003e\n\u003cli\u003eDecreased Transmission Movement Under Load\u003c\/li\u003e\n\u003cli\u003eMore Direct Power Transfer\u003c\/li\u003e\n\u003cli\u003eImproved Shifting Feel\u003c\/li\u003e\n\u003cli\u003eOE-like NVH\u003c\/li\u003e\n\u003cli\u003eComplete Drop-In Replacement for Factory Transmission Mounts\u003c\/li\u003e\n\u003cli\u003eSold as a Pair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTrack Density Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufactured from 70 Durometer Rubber with Void-Free Construction\u003c\/li\u003e\n\u003cli\u003eReduced Drivetrain Slop\u003c\/li\u003e\n\u003cli\u003eDecreased Transmission Movement Under Load\u003c\/li\u003e\n\u003cli\u003eMore Direct Power Transfer\u003c\/li\u003e\n\u003cli\u003eImproved Shifting Feel\u003c\/li\u003e\n\u003cli\u003eComplete Drop-In Replacement for Factory Transmission Mounts\u003c\/li\u003e\n\u003cli\u003eSold as a Pair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(1x) Transmission Mount Pair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePart Number Interchange:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e22 31 2 283 285\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\/Applications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW M3 2006-2013 E9X S65 4.0L\u003c\/li\u003e\n\u003cli\u003eBMW M5 2004-2010 E6x S85 5.0L\u003c\/li\u003e\n\u003cli\u003eBMW M6 2005-2011 E6x S85 5.0L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"034 Motorsport","offers":[{"title":"60D","offer_id":52090670842150,"sku":"034-509-4062","price":25.0,"currency_code":"USD","in_stock":true},{"title":"70D","offer_id":52090670874918,"sku":"034-509-4065","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0704\/2131\/5878\/files\/density-line-transmission-mounts-bmw-e9x-m3-034-509-4062-65-1.webp?v=1771013605","url":"https:\/\/store.ngpracing.com\/products\/034motorsport-density-line-transmission-mounts-bmw-e9x-m3","provider":"New German Performance","version":"1.0","type":"link"}
