I guess I need to research solutions for getting the camber back where I need it to be struts costing what they do, I wonder if monoballs would give me more camber adjustment??
-1.4 was the least amount of camber he could dial in for me, as one side was -1.4 and the other side was -1.2, with the the strut caps pulled as far outboard as he could get them....
Today I removed the rack spacers and raised the front end 1/4" and the car settled down quite a bit (but nowhere near "dead steady"), and this of course added some toe-in, so I'm going to have to reset the toe this weekend myself. Thanks for the tips guys.
I am running tire pressures: FT 32 and RR 34. I'll try 29psi up front as well.

For my driving style I prefer 30F/35R in my '82 SC, a coupe set to Euro height, with Bilstein HDs, corner balanced and professionally aligned. The specs I use are (F) 0.8 neg camber, 0 toe, 5.3 caster; (R) 1.2 neg camber, + 1/32nd of toe out (each side). The rear toe helps with turn in, but has virtually no effect on highway speed straight line stability. Also, I had 200 pounds (my approx. weight) in the driver's seat + a half tank of gas.
Different driving styles encourage different specs, but the above set-up allows me to stay with anybody on canyon roads, and it's a great compromise for fast sweepers.
If you can do your own alignment, experiment!
Was hoping to play with them this weekend. Hope UPS beats me home today.

I grabbed a different tire pressure gauge and found my front tires inflated to 34psi- apparently the gauge on the bike pump that I used is inaccurate... I brought the tires down to 29 psi and it made a world of difference on the freeway. There are some pretty bad roads here in SoCal.
I also reset the front toe to 1/16 toe-in. All these things helped considerably, but I can see that 1.4 neg camber will continue to give me some trouble up front. I will have to live with it until I can afford struts. The KYB cartridges I bought are also pure crap- not a good a choice for this car, and not worth the money I saved by not buying the Bilsteins.
Thanks again for the much needed guidance.

Many of you know I'm my own mechanic. My '88 911 Cab has not been to a shop the entire 5+ years I've owned it. No PPI, no prior experience with Porsches, no budget to speak of, and (the hardest admission) a car that was obviously badly neglected by its original owner if not just willfully driven on salted roads.
In the time I've owned her she has gotten a long list of restoration measures, modification, maintenance, and upgrades. Some simply to bring her up to being road worth, others because I wanted it that way. Heaven knows I've asked some stupid questions along the way and needed a lot of hand holding by many of you.
Since early spring the work kinda went into high gear. RS carpet, door cards, steering wheel, etc inside, and strut inserts, rotors, pads, sensors, hard and soft brake lines, parking shoes, and several other small projects.
Coming up this week is turbo tie rods, ride height and toe adjustment, back tires, C/V boots, and a full tune up, oil change, and valve adjustment.
Needless to say I've turned a lot of bolts.
With all this work, and I do trust myself to some extent, she needs a once over by someone other than myself. My local indy requires my first born, so that is out.
To the rescue is
Marc at Red Line http://redlineporsche.com/ , the guy that told me how to resurrect my Quaife LSD and introduced my tired G50 to Kendall Oil and GM LSDA.
I'm basically going to have Marc do a full PPI per Pete's instructions in the sticky above. Whatever he find that needs doing, I'll do. I just think I've finally got the 911 where it should have been to begin with, and Marc should be able to tell me if I'm right or wrong. I can't think of a more competent professional that will do this for me without killing me financially in the process.
Here's to hoping.
