The official alignment spec and review thread

I wanted to start this thread so we have a place to post up our alignment numbers and how we feel that alignment has affected handling. Please refrain from posting anything EXCEPT your alignment specs and your "review" of each alignment. When you add / update your review of a specific alignment, please edit your original post. If you get a new alignment, please post a new reply to this thread. Mods, please delete replies that are off-topic - it would be great to have an exhaustive list of alignment settings for various purposes (autox, tire life, etc.).

Black Forest did my alignment yesterday. Most significant change was max front camber. Rather than changing a bunch of settings at once (toe, caster, etc.), we'll start with one variable, see how that works, and try something else next time.

Front camber: -1.25
Caster: 6
Toe: 3.5
Total Toe: 1/16"

Rear camber: -1.75
Toe: 9
Total Toe: 1/8"

Review to come after tomorrow's AX.

Factory Alignment and the wear has been very even so far. I've got the stock 17" wheels wrapped in PS2's , I drive this car daily in a "spirited" fashion most of the time and autox it 9-12 a year.

Front
Toe: (L) +0.03 (R) +0.03
Camber: (L) -0.41 (R) +0.30
Caster: (L) +7.64 (R) +7.63

Rear
Toe: (L) +0.07 (R) +0.06
Camber: (L) -1.68 (R) -1.68

Factory recommended settings for reference:

Autocross about a dozen events a year, the rest just driving to work ect. I wanted more negative camber up front to reduce understeer but can't get more than half a degree without camber plates. I like the setup but feel it could be better with more front camber as it still pushes in slow, tight turns but not as much as it did.

Front:
Camber: -.5
Toe: 0
Caster: 7.5

Rear:
Camber: -1.5
Toe: .06 degrees in

Got my alignment done today at Roger Kraus Racing. I was able to get -1.0 deg with little twist on the strut mount. My car is a '99 with stock US suspensions.

Here is my alignment spec:
Front
Camber: -1.0 deg
Toe: 0

Rear
Camber: -1.5 deg
Toe: 0

The car is much more spirited now. It handles the way a sport car suppose to be, no more understeer, turn-in is quick and willing to rotate in middle of corner. I love the way it handle now!

Smart Strings is the way to go!

I'm fortunate to have one of the Flying Lizard's team mechanics operating his own shop here in Charlottesville VA (Here's the plug: Werkstatt)
Using his stuff, we did the Smart Strings alignment on a set of scales. We set the toe for both front and rear at an absolute true zero. Front camber was set at -3.2; rear was at - 3.6.
The car has never driven more true!
It's primarily an AX car, but I do drive it on fun runs/PCA events, and the occasional Boxster-to-work fix.
BTW, K-sport coilovers w/ monoball mounts; tarrett rear toe links

Front
camber= -0.7 deg
toe= 0
max castor

Rear
camber= -1.5 deg
toe= 0

The car runs about 20 track days/year plus lots of spirited weekend canyon carving. Very few highway miles. It still has mild understeer which can mostly be overcome by apexing later. The car tracks straight and true under all conditions up to 135 mph. Noticeably more wear to the outer half of the tires especially in front. It would benefit by more neg. camber on track days but I am limited by current BSX class rules.
