I just wanted to give a caution to anyone working on or changing the engine mounts. The Lotus Service Manual does not specify the bolt torques. Many people are using the torques that were listed in the installation instructions for Manly's inserts.
However, I think some of Manly's recommended torque settings are much too high (as evidenced by some damaged bolts when I did my installation). Over torqued bolts have a higher chance of breaking under load. See the following thread for alternative torque values and the rationale for them:

By-the-way, I installed Manly's inserts about two months ago and really like them.
