Semi-Solid Engine/Trans Mount FEATURES: Using the proven components from the 911 SS Engine mounts, these Semi Solid Engine mounts are designed to replace 1990 to 2009 engine mounts and the 986/987 transmission mounts. These semi solid mounts offer more precise location than the factory RS mounts - and do so at a lower price. An ideal compromise between the harshness of solid mounts and the cost of the factory RS mounts. The end result is a tighter feeling chassis, one with quicker left- right response, more predictable gear change precision and stability under braking. All with minimal increase in niose transmission. The kit includes the correct M12 bolt to install these mounts as replacements for the Hyrdoelastic O.E. mounts (that uses an integral stud). Two mounts required per car. Technical Note: The M12 bolt through the Engine or Transmission mount should be tightened to 40 ft/lbs or 55 Nm for the 993/964 & 986/987 mounts, and 60 ft/lbs or 83 Nm for the 996/997 mounts. The M8 hardware should be tightened to 18 ft/lbs or 25 Nm using the original arrangement of washer and nut. SALE PRICE-$149.00	Semi-Solid Engine Mount (ea), all 986/987 FEATURES: The Boxster SS Racing Engine mount is designed for competition cars and offers maximum control of the drivetrain mass – without overt concessions to NVH (Noise Vibration Harshness) . This competition series mount is installed within the original Boxster (986 or 987) mount, re-using the die cast aluminum housing and flat rubber isolator flaps that straddle the mount. Unlike Solid engine or transmission mount systems, the Semi Solid installation provides sufficient isolation from engine vibrations to protect your sensitive engine control electronics and instrumentation systems. The Boxster SS Racing Engine mount uses a 3 piece design, where a pair of aluminum hubs are completely isolated from the alloy housing by the elastomer pillow (orange part). This flexible interface between the two solidly mounted brackets - engine and chassis - is the key to managing destructive vibrations from being transferred between systems. Technical Note: The M12 bolt through the Engine or Transmission mount should be tightened to 40 ft/lbs or 55 Nm. The M12 Schnorr (serrated) washer should be installed directly under the head of the M12 bolt. The M8 hardware should be tightened to 18 ft/lbs or 25 Nm using the original arrangement of washer and nut. Note: Factory housing shown is not included. A press and selection of press tools will be necessary to remove the O.E. rubber mount prior to installation of the SS Racing Engine Mount in the factory housing. Installation of the SS Racing Engine Mount requires no special tools.
