I'd say it's more a subject of what terrain and how you drive that matters.

Good suspension is far more important for go-fast racing, where diff lockers are important for technical driving. Not saying that you don't need good suspension for technical racing, like crawling. But diff-lockers are pretty important there.

go fast racing in a jimny lol, true does matter what terrain I just think a really good suspension vs difflocks I would go with difflocks as anything suspension wise on a jimny needs a hell of a lot of work and money to be up to scratch were as difflocks are reasonably simple to do compared and proberly cheeper than a full on decent suspension set up

Sadly I can't link to any youtube clips.
But a danish racing team in a Jimny competed in the Breslau rally last year and finished 12th. Pretty good for a Jimny. I believe they have a M16 engine of some sort, modified to around 120 bhp. But not 100% sure. They use Hot Bits suspension with a 2" lift. So go-fast racing is possible, in a Jimny :)

A 2" suspension lift is not going to make it handle terribly, in fact my 3" lift is not bad at all!

Insurance with the right company is not an issue either, cost or cover wise.

Biggest limiting factor with any ridged axle and 2 bolt Hockey stick or radius arm set is as one wheel lifts and the other droops the axle needs to twist which obviously it cant you will always struggle with this set up and a ridgid axle unless you 3 link or
A frame it which is awkward and Expensive to perform don't really matter how high you jack it simple fact is the axle cannot twist to allow full articulation

I've been thinking about this all evening and after a bit of mocking up with a mop handle, 2 sticks and a coat hanger I think I've come up with a setup that would get around this without resorting to wristed arms and suchlike. Like a 3 link hybrid, still using a panhard rod for transverse location. I'll make a better mock up to prove the concept before saying too much!

This is pretty much what I'm trying to do. Keeping as much standard as possible, just getting the best out of what's already there. Ok I'm on 215s, not 205s, but I went for the best tyres I could fit without having to modify anything.

Looking at a few lift kits, they all talk about 'uprated springs'. I take it they mean higher spring rates? If so, surely they won't flex any better than shorter, softer springs? I don't want a tall Jimny on stiff springs that rides like a roller skate. If I'm forking out for more suspension travel I want to be able to use it, and have a wallowy Jimny that is so softly sprung it feels like it's floating and rolls in the corners like a Baja truck.

I wish there was a good resource for comparing spring sizes, lengths and rates from all sorts of vehicles. I bet there's dozens of OEM springs for other vehicles that would fit.

What is your intended purpose?
I can't really see how you're trying to compare it to Baja tracks that have suspension for tens of thousands of £££.
You need a spring that matches the weight of the vehicle. The uprated springs you mention are for Jimny's with heavy bumper, winches and so on. Try contacting Jimnybits for a set of springs that match you Jimny. And get a good set of shocks. If you don't want a tall Jimny, but want more articulation. Move the shock and springs mounts up, and make a 3-link setup as suggested :)
