Solid engine mounts (Z1), transmission mounts (Z1), subframe (SPL) and diff bushings (SPL or Z1). These transmit much more vibrations from your drivetrain. Good compromise would be the urethane versions.
If you do just the SPL arms, their spherical bearings don't increase vibrations much, but do increase the NVH and road noise a bit. Feeling to road surface is more direct, but won't result in unbearable vibrations. Will be a problem only if you are an audiophile that wants to enjoy crystal clear music while driving the Z, which can be remedied with extra sound deadening.
