Suspension Replacement: What to do "While I'm in There..."

[XanRules]

Hi folks,

My 2017 is creeping up on 90k, which means it's well overdue for a new suspension. I have a set of Bilstein B14s and rear upper coil spring pads ready to go on. I'll be doing the motor mounts as well since my aftermarket ones have about 85k on 'em.

However, given the mileage of the car, I imagine that there's some other stuff down there that's worn and needs replacing, plus maybe some stuff I'm not aware of that I'll need when I'm working on it, so I wanted to check in with everyone on what needs to be - or should be - done.

I have not opened the B14s - do they need strut mounts, or do they come with their own? I will presumably need a set of front strut bolts, such as those sold by @Dialcaliper in this thread (hello!), but what else? Are there any bushings/mounts/etc I should be looking at replacing? I see that, for example, Whoosh sells bushings for the front and rear control arms, rear beam to chassis, and the steering rack. Should these be considered wear items that I should replace while I am in there?

Basically - What else do I need, or SHOULD I do, while the car is up on a lift with the suspension off? I am looking only for suspension-related suggestions (ie, nothing related to brakes, wheels, tires, etc) and for maintenance rather than upgrades (ie, "add a rear sway bar" "add a traction bar," etc are outside the scope of this question)

Cheers!

When I replaced both shock and strut assemblies on my Honda CRZ, I also did the outer tie rod ends and the sway bar end links.

With the sway bar end links it was more about not having to deal with and reinstall the crusty mounting hardware, using new nuts everything was shiny and happy when done.

Another small step I took was while down there, I hit all the hardware and surfaces that seemed rust prone with Amsoil Heavy Duty Metal Protector. Seems to be keeping things clean over the years.

You'll need
* Front top mounts / bearings / boots
* Rear top mounts / boots (I took them off OEM ones I was replacing, they were in good condition)

Important: When they say dont tighten front top nut until the car is on the ground, that's good advice. It takes much less effort to counter-hold the shaft with that hex key and tighten the nut to spec than when its on a desk in a vice etc and you just may avoid stripping the hex (ask me how I know)

You won't need rear spring insulators; the kit comes with its own thin pads
Keep and reuse OEM rear top nuts; the ones that come with the kit are too wide and will rub on the body panel
I thought of replacing links but they were in good condition.

If I was to do this now, I would probably also replace control arms and the associated rubber bushings.

Re: sway bars, people say b14s need those but I found them to be surprisingly good without any add-ons. The car rotates wonderfully, with maybe some small PSI adjustment in the rear.

Cool, thanks, and noted on the rear insulators - they were given to me for free so I'm not out any money, but I'll keep the rest of this in mind as far as top mounts, bearings, boots, control arms, and bushings.
