Which is why you shouldn't try to change a springs rate by running a torch up
and down it.. This was a dumb, but common, technique years ago. Run a torch
up and down the coils until the car settled down to the height you wanted. Of
course, the car would continue to settle in use because the temper of the steel
was destroyed.
Change a spring rate by cutting it, that's fine. But don't run a torch up and
down the thing. You end up turning it into a non-spring that way.

Just got off the phone with a local spring shop. The guy said as soon
as you add heat to a coil spring, everything you thought you knew about
its spring rate and behavior has now changed. Formulas applied to the
spring 10 minutes earlier don't mean a thing.
