In April, having amassed some more funds, I bought –

4x new standard Jimny front springs, 4x JimnyBits “Black Raptor” brand +5″ rear Grand Vitara gas shock absorbers, and four spring clamps.
I don’t want too much lift with the buggy being short and narrow, but it needs to have plenty of articulation, so the springs will dislocate at the top, and be held in place by the spring clamps which are attached to the spring cups on the axles.
The shocks are 29″ at full droop and 15″ compressed, so that gives me plenty to play with when the suspension is setup during the build…
