992 suspension options ... confused

[alltalk]

Had my test drive today and they had a T, was worried about road noise but was actually OK, however I thought the suspension was actually not too harsh. Anyone know definitively what the differences are and any real world experiences of various combinations. If base or "s" is softer then will go for that but if same as T then that opens up more options as many more for sale. Fair play to Cambridge OPC gave me the keys and off I went so could try on roads I know. Took it back 30mins later as found out everything I needed.
