Do you know what rate these springs are, as looking at them they seem quite beefy? For this to work smoothly you need fairly weak springs as helpers so that they are fully compressed at normal rode height. Unless you are actually wanting them to work as a progressive rate compound system? It's just if they are too stiff then you will not have any movement in the slider section except at full compression. Ideally it needs modeling with some idea of the final weight of the buggy.

One of the last 200ish of the gen3s, probably.

Just browsing eBay, as you do, and some second-hand coilover springs popped up…
bid gone in
looking at stock suspension -
the cone with the bump stop on the bottom inside the spring looks to be 2”+3” long, and these are about 5.5” long, so should compress to 2” to 3” ?
(ones is 6.5” long but Mr.Angry will soon sort that
And they’re 2.25” internal diameter so will slip nicely over some 2” OD seamless tube roll cage off cuts I’ve got lying round, which will make the outer tube of the ‘pistons’ I’ve proposed above…

Too late! I won them last night for £22 delivered, so worth a look and a play…
When I originally zoomed in on the eBay hi-res photo I reckon they’re wound from 8mm wire and the coils are 20mm apart… they’re 5.5” long and I need them to compress to 2.5” - 3” to equal the stock position of the bump stop cone mounting, which I reckon to be about 4” below the spring seat in the photo now on the previous page, so the bump will actually be more like this -
To give me more droop and upward articulation with the long shocks (29” open, 15” closed so 14” of available travel not that I’ll need that much! Not with stock radius arms and narrowed axles…,)
So in my awful sketch there’s still another 2” of unassisted droop still available…
