On my 2009 Roadster the rear springs sagged in 2014 wt about 25k km... So you got more out of your springs than I got Jay! But then I am a bit heavier...
I got the Mulfab ones istalled and also placed a second anti tramp bar and Avo dampers, was a good improvement. The supplex rear leaf springs came to late, otherwise I would have considered those.
Cheers,
Bert
