034Motorsport BMW N52 N54 N55 Street Density Driver Side Motor Mount (1M, 130i, 135i, 330i, 335i, X1 & Z4)

Uprated Driver Side Engine Support for BMW E8x E9x E84 E89 with N52 N54 N55

Give your BMW sharper response and stronger driveline control with this 034Motorsport driver side engine mounting, engineered for N52, N54 and N55 powered models. The solid-filled 50A rubber construction and cast aluminium body deliver a taut, precise feel under load, cutting unwanted engine rock and improving gearchanges while keeping cabin refinement intact. Ideal for spirited road use and fast-road builds that demand reliability and performance.

We have run this mount on our own cars at MJ Modifications and customer feedback has been superb. Expect crisper throttle pick-up, noticeably reduced driveline lash and more immediate power transfer without the harshness you get from many polyurethane solutions.

Why this uprated mount

• Stiffer 50A rubber element compared to factory hydraulic mount for firmer support and longer life
• Void-free and fluid-free design resists collapse and leaks common to OE units
• Rubber works in tension, compression and shear, controlling movement in every axis
• Cast aluminium housing produced to OEM-level standards for durability
