Good question! I don’t have an answer 🙂 I’ve had a single rear shock lose pressure on both of my CM cars and, in both cases, the car became evil to drive. Turning was hugely inconsistent, from ugly push to snappy loose. I never degassed any of the shocks on my stock class cars and I think I’m glad I didn’t. But, yeah, I’ve heard of others doing it but never thought it made sense???
YMMV
