Also have a PM35.
Pretty sure the suspension is the same as the RWD 2.5Ls (which I think are fairly rare...)
Mine was a whale when it first came in, but have since added Nismo swaybars, OX rear brace, Daleo's front brace, and just done the bushes on lower control arms and sway bar mounts.
Handles very well now... Was even chasing 2 WRXs around corners
