Yea no big deal, I just figured they were left in like mad polly ones, guess not.  So I'm assuming that every mount requires the outer ring to be removed for the Prothane inserts.

The reason being is the prothane mounts have a lip around the outer edge...not sure if the madpollys do?

I think it's important to point out the difference between the mad polly instructions above and using the prothane inserts is that you need to remove the metal outer ring (at least on the timing belt mount) when installing the prothane mounts.  Polly calls for leaving the ring in.  I spent more time than I care to admit cleaning that outer ring, only to find that my prothane mount won't fit when leaving the ring in.  I'm also assuming you will need to leave the side cushions on the timing belt mount too.

my brother fitted Bride seats into a Proton (same as Lancer). He used the Recaro seat rails from the EVO 1-6.5 and a custom made mounting plate on top of it. i.e. fitted an entire plate to the bottom of the Brides, then made holes in the plate to bolt onto the EVO rails.
