I am at 120k miles on a 2015 and still on OEM struts. Cannot get the whole suspension kit for the front end like the 2014's which are available via KYB. Ideally would like to replace the complete suspension but it kind of gets expensive...

So my big question is for any metallurgy experts in this group,

Does the suspension spring metal fatigues and gets softer over a period of time/cycles?

If I am touching the front suspension I want it to come as close as possible to a zero-mile state, but if older springs are going to make the front end softer/harder, then I would want to replace the springs and rubber components as well...

Anyone who has done this can please chime in......
