Mine only squeak in when it below freezing. You don't have to constantly take it apart and grease them. Before you install them, grease them good with a good lubricant and you'll be fine.
camber will be set to less then 1 degree, front toe at +.05, rear toe will be set at +.10. Hopefully this does the trick, only thing I can think about is the super soft bushing all around is flexing too much .
Good luck! Keep us posted!

I would advise against positive toe. That's going to make your car relatively darty and unstable, particularly at speed. That's more of a track setup for sharp turn-in. All things being equal that's also a recipe for increased wear. You want to be as neutral as possible during normal rolling down the road driving (commuting)
my rear cambers were a bit aggressive for a highway car, -1.6 driver side and -1.9 passengers side.
500 miles so far on this setup
final alignment specs
RCF LCA
SPC rear camber arms
fronts:
camber -.4, toe +.05
rears:
camber -.08, toe +.11
driving characteristic is more inline with what the car is meant for, highway mpg car. I have notice less drag when coasting, turn in is slightly better and wandering on the highway is the same as before without the RCF LCA.
This setup is probably not ideal for someone looking for better handling, it pretty much handles the same as a stock car without tire wear, it is set up for long tire life and daily driving duties. Will update once I get more miles.

Cars with factory 3IS lca will need some positive toe if they want to prolong tire life, people who go the poly bushing route can get away with zero toe because it basically neutralize the dynamic toe changes.
