What suspension pieces do I need v. lowering
 

Ok so I know very little about suspension. When I ran into some money I picked up some tein basic coilovers with pillowball mounts on the fronts. I lowered the car very low for a while and then realised that because of camber and tow problems I wore my tires like crazy on the rear and rear only. The fronts are fine at any height but I am just wondering what pieces do I need for the rear to take car of tire wear and handling issues when my car is lowered. I am thinking I need RUCA's and new rear toe links. I was also wondering what pieces comprise the S14's suspension (yes I know it's MacPherson) and what does each piece do.

Thank you!

You need new RUCA's and i would just pull some negative toe out of it via stock toe adjustments. Lowering a car natuarally introduces negative camber and negative toe angle.

Should I just get adjustable toe arms as well? I don't want to have to worry about uneven tire wear or handling problems.

i would get ruca and rear toe
and get a full front and rear alignment.
like... at a shop. no eyeballing crap.

components... go to splparts.com and look at their suspension diagrams. front is tie rod (toe), tension control (caster) and camber plate (camber). rear is rear toe link (toe), ruca (camber) and traction link (rear bumpsteer).
