Please help me sort out my suspension!

[NoMoSHO]

Hey all. I'm trying to dial in my 2015 GT non-pp for daily driver/road trip use. When I bought it last May it had 136k on it, it now has 141k on it.

Here's the current situation, pretty much as I purchased it:
- Lowered on Roush Yates by Vogtland springs, from what I've found so far this is about a 1" drop. Unknown spring rate.
- Stock (original?) front struts.
- Stock (original?) rear shocks were toast, replaced with Bilstein B6 immediately after purchase. Did not cut stock bumpstops, regretting that decision.
- Clunk in the front end when changing direction forward/reverse, figure one or more ball joints are toast.
- Stock 18" wheels, worn out 235 tires with a lot of inside edge wear.

This thing is kinda sketchy in its current form! Hoping to change that. I'd like to stay lowered, since it looks cool.

Here's my tentative plan, with some questions:
- Springs? - the existing springs ride *fine*, but curious if there is a silver bullet option for my purpose. Just looking to take up some wheel arch.
- Blistein B6 front struts.
- Stick with the B6 rear shocks, maybe also J&M adjustable upper mounts? Would I notice having the extra travel back? Will also cut the bumpstops.
- Steeda 555 4915 kit for roll center/bumpsteer correction. Have new Delphi tension links already, figure may as well replace all 4 control arms as they are original.
- Picked up a set of OEM 20" Foundry wheels, to pair with a set of 4 275/35R20 Firestone Indy 500s. Love the way they look on a lowered S550.
- A long overdue alignment.

Any suggestions would be appreciated! Thanks in advance!

I would replace all front LCA and tie rod end first.

Absolutely planning to. Pulled the trigger on the Steeda kit and the Bilstein struts today. Hoping to knock all these part changes out at once to avoid excessive downtime and extra alignments.

Definitely trim the bump stops. Or better yet get the ones mentioned in this thread instead. I made the same mistake initially and it made a big difference in ride quality when getting it right. Also agree with the recommendation to get the Performance Pack front control arms.

I personally really liked the FP springs, and they are about the stiffest spring you can get up front. You want as much spring as you can get up there. And no "canned" spring package from the big MFG's really gets you close to too much spring.
