Displaying LEGO Technic models & suspension

[Jetro]

When you display a large(ish) Technic (car) model on a shelf for a long period of time, do you take any precautions to protect the suspension? If you do, what and why? Have you had any negative experience or are you just being extremely cautious?

I tend to support mine with a simple frame, since springs seem to lose strenth over time.

I've build various simple frames. Just to keep the wheels off the ground and the model tilted. 

I've started with one and now a build is not finished without a stand.

This one is not mine but can be found on rebrickable.

I don't worry about it at all, but my heaviest model is the 42110 Land Rover.  The only set I've seen problems with was 8479 and it was the front axle wheels because the axle only goes partway through them, it started cracking the wheel.  So I switched to longer axle with stop (4L, which didn't exist when the set was made) and I feel fine with that.

Under some models I have placed transparant bricks. Like the 1989 batmobile, but that is more to save the tires.

I put support under the chassis of heavy weight structures such as 42082, 42131, 42146.

I  have 8880, 8458, 8461 stored assembled without support for more than twenty years.

However, I have inserted a ring made from corrugated pipe as a support into the rear wheels of 8284 and 8455 since the tyres tend to flatten within weeks from assembly.

Another possibility would be (thin) liftarms for taking off the load from the springs, but this needs to fit the suspension construction somehow - just mentioning for a standless possiblity which may be hidden behind the wheels for allowing to place a model on its wheels without sagging over time.

I guess another option, now that we have the 4.5L axles, is to make a 6.5L long construction with one of those and two #1 connectors to replace the 6.5L shock entirely, though that would be kind of sad to delete a feature

The only models I’ve had that have sagged to the ground are the ones with rubbish suspension design (eg: front of the Bugatti Chiron) But I solved this by redesigning the suspension instead of gimmicks with how it’s displayed.

Thanks for all the input!

I was thinking about this. I've seen some sagging in a few models but isn't always the springs that are at fault.

Ooh I want to try that. Looks interesting!

Wait, what? I missed that. What set? And why 4.5L ?

On the majority of my Lego Cars & F1 models the arch gap or ride height becomes better after a period of time. I will happily replace the shock absorbers on any models that totally give up.

Technic, Axle 4.5L with Stop : Part 7784 | BrickLink

Can't definitively answer why- I imagine they thought it was useful to have. I certainly do.

Have a feeling it was actually developed for the Pokemon set, when you see how it's used, it makes total sense.
