Alignment for lowered Z

Can't speak to D2 springs, but with my Eibach Prokit springs, I used additional suspension components to keep my Z in alignment specs.

Its stock suspension besides the lowering springs. I believe its has a toe issue. I am wearing out tires on the inner side of the tire, down to the belt, within spring-fall driving season.

Toe is about the only thing that can be adjusted stock correct? So you are aligning everything yourself? Ive watched a bunch of DIY alignments on youtube thinking I might take a stab at it.

Depending on how low your springs take you, camber may be so extreme that you'll wear out the inside of your front tires no matter what you do. Have you looked into some adjustable front upper control arms? SPL makes a nice set:

Definitely a combination of toe as well as caster and camber. Not hard to see why. Lowering a car changes all of the suspension angles naturally. Bringing it back into spec (or to your desired performance spec), you need adjustability, something lacking in the stock suspension.

Adjustable FUCAs (front upper control arms) are REQUIRED for any lowered Z. SPL is top of the line but if you aren’t racing, you don’t really need them (plus they’re very $$$). Consider SPC as a good street/hills/track day alternative. I don’t usually recommend any of the others as SPL and SPC do NOT require any disassembly for adjustment.
