How Exactly Do Barrel Springs Improve Damping on the CC-01 Chassis?

Cross-country barrel shock springs work differently than your standard damper spring. Why are they so good for some TRF (Tamiya Racing Factory) aeration oil-filled dampers on Tamiya's CC-01 (Cross Country) chassis for R/C model vehicles like the Mitsubishi Pajero/Montero and also can surprisingly work (with some serious modifications) in the ORV (Off-Road Vehicle) chassis? We dig deep into the physics and material science on these CC-O1 barrel shock spring set in this episode of the RC Deep Dive podcast.
