I am in the process of replacing all my springs. While none of them were actually broken like I have heard happens with the OEM's ,I believe all of mine had weakened over time. I think this is caused by the EDC shocks,struts wearing out or leaking prematurely and putting too much strain on the springs,thoughts?

Why do you believe they have "weakened over time"?
Any evidence for that?
I have had 3 BMW's, 1 Saab, 1 Ford, 1 Subaru, 2 Volvo's over the years.
Only the Saab had a spring issue last year at 14 years old and 40, 000 miles.
Why replace all? In that case, why not replace the dampers as well?
My 2010 is still going well with 60,000 miles.

FWIW on my 35is at 50k miles, August 2022 , 2011 MY, the rear springs were utterly shot..what came first the shagged dampers or soft springs ? Not sure but both dampers and springs were shot..front dampers were leaking, springs had softened but no where near as bad as the rears..
The springs support the weight of the car. The dampers/struts etc just stop the spring bouncing uncontrollably. Knackered dampers will not bother the spring.
Springs can loose some of their strength over time but it’s much more common these days for bits of them to snap off. That’s not unique to BMW by the way, just walk along any major road you’ll see bits of broken spring everywhere.

I did replace the front dampers as they were leaking and shot ( very easy to push in and NEVER came back out),the rears seem ok and are not leaking-going to keep an eye on them. The springs are known to weaken or break after as little as 40k miles,just do a search on here to satisfy your curiosity.
