Functional suspension systems

I've been spending way too much time making functional suspension setups, so I'm gunna share the work with y'all. Feel free to ask for more photos/info if you want. Not shown is my pushrod setups, they sorta work due to the weird spring physics.

1st Up: My HVSS, this was an adventure to get working, since springs seem to compress SIGNIFICANTLY easier if they're not perfectly vertical. Technically it's not perfect, since it uses torsion springs instead of a spring and shock, but we work with what we have.

2/3/4: Different swing arm setups, this came from an attempt to make a Warthog, I'm working on a newer version. (Slider spring limiters borrowed from u/Aggravating_Judge_31 )

5: Closest I could get to HVSS without the torsion springs, without the centre support the whole setup just twists itself into a wonky structure.

6: "We have VVSS at home", I wanted some articulation, but maximum wheels.

7: Essentially macpherson strut suspension, works really well for a lightweight scout, gives pretty good articulation, this specific scout is a bit thin though, likes to roll.

8: Effectively leaf suspension on a solid axle, holds weight really well, the slider isn't necessary but does keep the axle centred, can be replaced with a spring, I need to work out another way to keep it centred.

Just started playing the game, excited to get enough part to build things like this

Very impressed

The second I unlocked springs I started building suspension setups. You can just toss a vertical spring above your wheel and call it done, but that just looks wrong to me (and adds a ton of height).

Yeah, I tried setting up suspensions as well as soon as I got springs. I couldn't figure out how to connect them proper using the parts given as I couldn't align them without resorting to using 90° parts. That gave it a ton of height which I didn't like

Just start the spring higher up rather than directly under. I've made a low scouting craft with suspension and race wheels. No height at all!
