Hi Tim. My 2009 Plus 4 is suffering from a second sagging rear spring ailment in 22k miles. First replaced after about 15k miles. So I am looking at the options to replace. As you said the SSL 5L is probably an expense too far, so I would be interested in your satisfaction level with your set up, also were the leaf springs standard MMC replacements?
I'm very happy with my setup, I bought a set of 4-leaf rear springs from Mulfab. I think they are the same springs as fitted to the 4/4 Sport but you'd need to check with Peter.
