Suspension Bolts Replacement

What hardware should be replaced when installing coil-overs? I'm putting a set of KW Clubsports on my e92 m3 with almost 50k miles and want to freshen up some of the parts/hardware. Should these be replaced with every suspension change?

Anyone who tracks or has experience with this let me know.

Rear schock mounts. You could also replace the rear lower shock to control arm bolts if you want.

Nah the front strut slides into a sleeve of the spindle. No load bearing bolt there as it's held by a compression collar.

Replace the rear shock mounts if they don't come with new ones.

Unless there is damage/cross threaded/head rounding/rusted. You shouldn't need to replace any hardware.
