Which coil spring to use with Bilstein 5100 strut?

[Dearmosd]

I have a pair of GM 23312164 (6ZR/7ZR) and pair of GM 22826290 (6SH/7SH) coil springs.

I purchased a set of Bilstein 5100 struts and before spending the time figuring out which spring would pair better the the Bilstein 5100 struts I was wanting to see what other people were using with their Bilstein 5100 or passive struts.

I cannot find any info on spring rate so I dont know which is more softer then the other. People post their strut decision but no mention of the spring choice.

I finally found some numbers in reference to the two springs I had to select from

22826890: Spring Rate 682.93
23312164: Spring Rate 599.56

I tried both with the Bilstein 5100 and although the 23312164 felt great I think the little extra stiffness from the 22826890 felt a little better.

Also to note, the Magneride upper mounts would not work with the Bilstein shocks. Had to use the 6SH mount

@Dearmosd what year with magneride were you working on? I have a 2019 and I’m bout to make the switch to the 5100s. What all were you able to swap over? Do I need to buy any extra parts? Like the bump stop, the boot, lower spring mount aka perch? Thanks
