FWIW they have revised the Model Y suspension for 2023. Reports say it is more comfortable without affecting handling. Some owners have reportedly ordered the parts from the 2023 vintage and had them installed on prior year models - but I haven't verified that so YMMV.
If reports continue to be positive that it doesn't negatively affect handling I may give it a try (depending on the cost). Of course another great Tesla feature is mobile service... I'm curious if they'd be able to do a suspension swap. They can already do tire replacement and rotate/balance. You schedule it in the app and they show up at your house to do the work. It is extremely convenient.
