Suspension and Bushing Refresh

[forevercasual]

I'm coming up to ~100k miles and was looking to refresh some suspension and bushings. I'm looking for any input on things I should update while I'm in there. I have a distinct clunk while backing out the driveway that I'd like to address (full lock). I don't mind some NVH but I'd like to keep it close to stock (CPE rear motor mount was too much for me). I'd say the main goal is for future reliability without losing the character of the car. Any input is appreciated.

Current plans:
Replace stock shocks with B8's paired with previously installed mountune springs
New reusable lower strut bolt set
Replacing stock driver/pass side motor mounts with powerflex bushings

if you are looking at a "set it and forget it" parts, power flex inserts ARE NOT the way to go. they're kinda meant as a sacrificial wear item that might disintegrate at the wrong time. At best, it'll wear and you'll need to replace it down the road and it's something you're supposed to check periodically.

most people here (including me) would recommend vibratechnics softest mounts as a great OEM upgrade.

Only thing I can add to this is that if you're going to be replacing the rubber bushing with Polys, you'll need non-petroleum grease to maintain these and if you're anywhere near the sway bar bushings.. best add teflon tape to the sway bar at the bushing contact point.. otherwise you're going to hear some squeaking.

I haven't heard or experienced this on the powerflex inserts, but good to know.

me looking at my powerflex rear motor mount inserts with 50k miles looking great...

I haven't heard that about the powerflex inserts either, but I'll see what I can find.

Anyone have any input on whether there are other bushings that would tend to become sloppy at this point and should be replaced as a maintenance item?

Control arm bushings but it would be cheaper to just replace the entire control arm, sway bar bushings and don't forget to replace the rubber/poly isolators within the strut and replace the top strut mount. You may need to check the trans mounts also.
