i think imma do this, which side you think would benefit the most?Tip for those with the Delrin solid motor mounts:
Install one side only then drive the car for a week before you decide whether to go full solid mounts or a hybrid solid/MS mount setup. You'll be surprised how much more rigidity you'll get even from one mount. Better to do half the job than replacing a mount twice because it caused too much vibration.
I know this from personal experience.
