From what you say my 2009 Roadster may have "poor quality" 4 leaf rear springs. After 24000 miles I guess that I need to check for a "saggy bottom"

You measured your 2012 as follows:
To underside of running board at rear (just in front of rear wheel):
Old springs: N/S 21.0cm, O/S 20.4cm
New springs: N/S 23.8cm, O/S 23.8cm
Gain .............2.8cm, ... 3.4cm

I measured the same place:
Aldermog N/S 20.4cm. OS 19.6 cm

This suggests that all isn't well. Unless the roadster is different...What are the measurements on your Roadster?

I'd planned to fit a Panhard rod and AVO rear shocks, hope I don't need new springs as well?
