Hi Brad, I drove it- cautiously, for 3 days incl an amazing trip up and down MT. Baker in NW corner of Washington state. I thought I had a ton of toe-out as I had REAR bump-steer! Very unsettling. It was at -1.8 camber on RR and similar on LR. Today I moved both camber eccentrics to the opposite extreme (pulling the bottom in) dropped it, tightened, and used a string to compare the front side to back side of the rear tires. It looks like I've got about .2" of toe-out now and about -1 camber on both sides. On a brief drive it felt good- no more bump-steer at all. Tommorow I'll get it aligned again. Is it normal for the camber travel to take away toe-travel on these cars? Oh and thanks for the tip on spring removal- if only I new that a few months ago!
PS. You previously said in an other post about alignments that you knew a way to remove all of the slop inherent in stock suspensions without replacing a single part --Will you elaborate ?? I can't figure it out!
thanks

Call me tomorrow:
714-987-2981
Take notes while I speak, you'll understand when I tell you 
I got sucked back into SCCA AutoX.. where you have to be VERY creative with the rules
I'm lucky to have the fastest Boxster/Cayman guy in the country as a customer (proven on Speed channel in "King of the Curve")
FYI:
Strut based suspensions are BAD.. when it comes to toe gain in bump. Especially on car with rubber bushings everywhere

update: had the alignment checked- bad news- RR cam. -2.1, -2.2, RR toe .24 total toe -IN! It just won't come in enough. I want half that cam and 1/32 toe- in. What's preventing it from getting there? Could it be that the strut hat is indexed incorrectly, say by one bolt spacing? Everything seemed to line up perfectly during assembly. Nothing appears bent.

By eye, how far off are the camber eccentrics from side to side?
Count the graduation marks and make a common reference point from side to side.
If the camber marks are way different side to side.. something is tweaked/bent.
The *only* time I have an issue with toe? is when we go to low on a car that I'm not allowed to run double adjustable race style toe links 
Remember: camber effects toe. Too much camber? You'll never get the toe back to zero!!

SHOOT and POST pics.. I can't be your eyes if I cant see what you see!!
Use brake clean and an old tooth brush to clean all the adjusters (with the marks on them)

hi Brad- The adjusters are the same on either side- I moved them there. Also, we even loosened the top L and retightened while pulling it outward - no change to the numbers. Is -2 cam a big deal on these cars, and the toe problems an expected outcome at -2 CAM?
I'll attach pics in a bit
PS. my car should be and looks like, it's only 1" lower at RR- I'll measure tonight.
