springs openion

i have been looking around for a new set of springs for my jimny i have the procomp 3" not very impressed after 2 years flattened and now also leaning on a side , considering i use my car 4 to 5 times a year just offroad and already gone
i have came across the PROGRESSIVE SPRINGS has anyone tried them on jimny they seem quite good and extendable so more articulation.
my jimny is still petrol but have steel bumpers and full rollcage so have gained some weight what do you suggest

like these on the right

TomDK has used the Zanfi progressive springs. I'm sure he will be along and give an opinion.

I have OME with the front being for the diesel Jimny. I also have steel bumpers but have found the diesel springs to be a little too stiff. I will likely change to the petrol springs designed for use with a bullbar. The Trailmaster that Martin sells would definitely be on my short list of choices. Just for reference, this is a table I created a while back for comparison. Martin has also inserted it into one of the wiki articles.

I bought those Zanfi springs from Tom and am using them now. Tom went back to the trailmaster springs he had before i think.

I Changed to +3" Zanfi diesel springs all round and AVO adjustable dampers from a trailmaster +2" comfort kit. The springs work well, nice even articulation and comfy ride, no funny noises or wobbling. Pretty similar to the +2" trailmaster for comfort but better as i can set the dampers where i want now. How they will last is an unknown, but i would expect better of them as they are so much more expensive than the procomp stuff.

Extra weight wise i am carrying a fair bit more than a standard jimny, so the diesel springs work well for me.
