Yeah probably overthinking this if Tesla doesn't have any additional vibration isolation. I would imagine a pothole/square edge bumps are fairly harsh in a Tesla given the limited suspension travel so the modules themselves must be designed to withstand that. I have designed vibration isolation systems and dampers which is why I was thinking it would be a good idea. Initially I was thinking just to mount 4 vibration isolators with studs but packaging the battery packs is a huge challenge with very little clearance so between frame flex/isolator deflection it might end up causing more problems with potential interference if it isn't needed.
