For 20mm drop you can add adjustable LCA if you want to pull out some rear camber from the drop.

I bought MOOG adjustable LCA via rock auto which are reboxed SPC arms but cheaper. The design is a bit of a PITA to adjust compared to other adjustable LCA due to the location of the bolt, but it isn't something that needs to be adjusted often.(thinking of your alignment tech

)

SPC toe arms are worth considering. I've had one of the stock toe arm slip on me last summer during autocross. I've read this isn't common but can happen.

New rear suspension arms, thought that might be coming. Will add to the list, thanks again for experienced input.

For reference, I've been running the stock alignment numbers the whole time so far, about 4-5 alignments done. All my tires have worn dead flat across the tread side to side. Should I just match that once lowered a bit or does anyone have more secret sauce?

You may or may not need rear lower control arms depending on where you camber lands after lowering. More than likely it'll land in an acceptable spot tbh. If it's super off, or you want ocd perfect, then you'll need control arms.

You can run factory alignment specs if you're just completely happy with it. Depending on how aggressively you drive you can dial in -2 to -2.5 camber in the front with 0 toe and -1.5 to -2.0 with slight toe in in the rear. Generally stick with a .5 split between the front and rear. That's at least what I've seen most people suggest from what I've researched.

These cars like more negative camber up front. I would do between -2 degrees of camber up front. helps with turn in and fun. Should have very little impact on tire wear.

Some camber/crash bolts with springs/struts is cheap and easy camber. One lower bolt is good for 1°. Add crash bolt up top for an additional 1°. Make sure wheel offset is considered as it moves the wheel closer to the lower spring perch. With coils this becomes a non issue.

Toe settings can fine tune handling. I've tried a few different settings over the years. 0 toe front, 1/16 inch toe in rear is a good stable setup. Tightens up the rear end on corner entry/exit.

My most current setup was done by a race shop that's trackside at CMP(Calabogie) who took very good care of me. They made a few adjustments after driving the car a few times but I believe it was around 1-1.5mm toe out 0.5-1mm toe in rear.
Toe out makes the car want to change directions faster. Downside is that it makes the car less stable and Darty on the highway.

Taking notes, thanks for the feedback. Ordered some used LCAs today. Installed the camber bolts an alignment or two back, but just had them set it to stock. Hopefully, all that will change soon for better handling, that's my goal.

Also ordered the MCA traction mod, research and feedback convinced me it's worth a go and I would like to plant this 14 FRS rear end a bit more as well. The softer ride characteristics reported will be good for my commute. The better rear grip is what I'm after.

This all in prep for some coils. Been looking, leaning CSG spec Tein Flex A or some flavor of RCE. Not sure yet, or married to either brand. But I do want to end up with rebuildable units as I have no intention of parting with the car anytime soon.

If you do want CSG, alot times there are longer lead times for the Flex-As so check with CSG soon rather than later.

Rear LCA's and MCA traction mods on the bench. Next step is the MCA mod install. I know it's more expensive, but I like to make one change at a time so if something goes wonky, I know which part it is giving me grief.

Been battling rear end softness/shudder since the 350 ftlb clutch install of late. But that's a different threads discussion. Cusco brace is better than the Whiteline insert kit.
