Spoke to the guy at Llama just now. V helpful, good bloke, but doesn't do springs anymore, got fed up with hooligans and unjust warranty claims. Has suggested I speak to Jones Springs (Midlands somewhere) - I'll try that, report back.
Everything else I've found (OLd Man Emu, Iron Man, another Aussie one (forget name) all +40mm or so lift. Trailmaster gone off radar, no response to anything (Jimnybits have same problem).
This is proving a lot harder than expected.

I found Jacob at Devon 4x4 very helpful but, like you, I wanted standard springs.

Drawn a blank everywhere on OEM spec springs. +40mm easy, but standard no-lift impossible (so far).
I'm considering having Jones Springs (Midlands somewhere) recondition a set of originals. Either take mine off or buy some from a breaker (think I have a source).
QUESTION: anyone know spec of the springs unloaded (off vehicle) - basically lengths centre - to centre, and amount of bow. I have a manual (official Suzuki I believe) and it specs bow when on vehicle but it will surely be more when it is off vehicle, it'll compress when loaded I expect.
What info I have is in pic - any more detailed springs spec anywhere?
