ST engine mount rules:
14.10 J. Any engine or transmission mount is allowed provided it attaches
only to the original mounting points, does not relocate the engine/
transmission (other than incidental to changes in compliance material),
and weighs no less than the OE mount. All components between
the engine/transmission and the mounting structure are considered
to be part of the mount assembly.
Mounts that I've found so far:
Beatrush - http://www.rallysportdirect.com/Beat...rce=GoogleBase
Megan Racing (look like stock mounts) - http://www.frsport.com/Megan-Racing-...FQUFnQod5RAAyw
Cusco mounts (need 04-05 mounting plates to fit 06+) - http://www.rallysportdirect.com/Cusc...smission-Mount
Perrin - http://www.perrinperformance.com/p/2205
Torque Solution - http://www.torquesolution.com/Subaru.../ts-su-200.htm
Time to get some weight measurements on the options...
