This crawler got it's wings

These wide tires can be referred to as floaters. In this case, it's all about spreading the load out.

Some drivers are also referred to as floaters. Those with manual transmissions who do not use the clutch, aside from starting/stopped.

What happens to the disc/s torsion springs during launch.... they compress. When do they return to the natural length? When (IF) the clutch is depressed.

Unless you depress the clutch, at least once, the springs in the clutch remain compressed. It doesn't matter when you use the clutch pedal, but the sooner after gear selection the better.

If this is not your practice, eventually the springs become frozen at shorter length set and fall out.
