Some of the techniques suggested are...not well thought out. Solid mounts are a bad choice. Based on too many road course laps and lot's of burnouts there are real world results.
With any type of torque strap holding the drivers side - the passenger mount gets compressed constantly and eventually collapses a bit-enough to tear the right side muffler hanger. This problem is visibly evident in pictures of the car under hard acceleration.
The best hardware is the schumaker [sp?] torque strap mounted on both sides of the engine and quality mounts like mity mounts. Yes 2 [two] torque straps as one does not work. The schumaker set up adapts well to the passenger side. Yes it was road course tested and it made a noticeable difference.
