info needed on using 7 series motor mounts

[JRKOUPE]

Ive been gathering info for the soon to be s50 swap.....

My main mechanic ( who has an m50 swap himself) swears by the fluid filled 7 series mounts( I dont know the vintage off hand)....I cant find much here on the forum re those?
Hes used both the m5 mounts and these....he swears by the 7 mounts.


whats the low down on them?...
any users here?

I was kinda set on the m5 mounts.......or IE poly's......I love the IEs on my m20.

TIA!!!!
