New Dampers & Springs Install - Replace Bolts?

[RElias21]

I will hopefully be installing the Evolve-Bilstein dampers and the MSS springs in a few weeks.

Should I be replacing all the bolts?
If so, anyone know if I can buy an entire kit with all the bolts, or at least a lot for damper bolts and a kit for spring bolts?

Thank you!

Most owners will reuse the existing bolts with no issues.

The only one I would replace is the pinch bolt that connects the knuckle to damper and torque it correctly. If not torqued correctly it may click when turning at slow speeds.

I’ve always reused the original strut and shock hardware when installing aftermarket strut and shock assemblies. No issues so far after 25+ years.

The pinch bolt is not a TTY bolt so it can be safely reused. However, if any hardware is to replaced, that’s the one I’d replace (typically only if its been reused several times). The second one I would replace is the nut at the top of the strut to top hat/camber plate but those typically come with an aftermarket setup.

I've uninstalled and reinstalled my suspension about 10 times now. I've always reused my bolts. However, I did replace my pinch bolts the last time around. I'm not using my car like a F1 car, so I think replacing it is just overkill. On BMW's part, I think the recommendation is just to cover their liability or just a money grab.
