Solid UHMW engine mounts for your M52 & M54 powered E39. Under hard braking the stock mounts allow the engine to pitch forward and to the side. These solid UHMW replacement mounts stiffen the engine and drivetrain, dramatically changing the responsiveness of your E39. These solid UHMW mounts are a direct replacement for your original 525i, 528i & 530i BMW OEM rubber motor mounts.

UHMW is an excellent general-purpose plastic with a unique combination of wear and corrosion resistance, low friction surface and impact strength. It is resistant to chemical attack and moisture absorption and retains key physical properties to -30 C.
