Just wondering what my options are in regards to stiffening/freshing up my engine mounts in my EF8.

I see engine mount inserts from Energy Suspesion for DC2 and EG. But ofcourse nothing for JDM EF.

I also hear people fill their mounts with certain resins or substances?



So what i am wondering is, how many mounts are there for the engine in an EF8. Are any of these mounts the same in another car? And suggestions on what to do with them?
