Progressive Springs

Hi,
I've just come across this topic and wonder whether you bought the
progressive springs in the end and how did they turn out?
Are there any mountings that need changing with replacement springs?

While there's always plenty to spend money on with a Jimny I had a thought that I might change the front and rear springs (all standard) as they're getting rusty. The web link you posted suggests they're about £170 a pair for progressive springs which is less than the Jimny shop charges for standard springs so they look a bargain too, although the likes of eBay suggests you could buy standard springs for much less..
