I took my car in to get it corner balanced and to get an alignment. The corner balancing went very well, but the alignment presented an unusual problem. On the passengers side front the camber locked out at -1.20 and he said he could not reduce the negative camber any further.

Here are the particulars:
The car will be driven almost exclusively street.
The car is a 3.2 6-conversion with steel flares
I am running Kumho Ecsta 245/45 17 rear and 205/45 17 front
Bilstein sport shocks rear and sport struts front
100 lb rear springs
Elephant Racing bump steer kit
911 turbo rods and front suspension with factory 911 sway bar
Weltmeister rear sway bar

Here are the before and after numbers:

Before/After


Caster:
Left 5.51 5.06
Right 4.86 4.55

FRONT:
Camber:
Left front -1.33 -1.00
Right front-0.91 -1.20
Toe:
Left front 0.07 0.15
Right front 0.16 0.17
Total: 0.23 0.32

REAR:
Camber:
Left rear 0.20 -1.01
Right rear -0.08 -0.34
Toe:
Left rear -0.30 0.05
Right rear 0.21 0.28
Total: -0.9 0.33

Thrust Angle -0.25 -0.12

In doing my research here, I came up with what I thought would be a pretty good set up for this car. -0.5 for the front caster and -1.0 to -1.5 for the rear, and 1/16th toe in all around. He started on the rear first and could not get the toe in to come in so he finally took all three shims from the drivers rear and ended up with these numbers. The 3 passenger rear shims were left in. He then went to the front. When he got to the passengers side, he said it was lock out at -1.20 because the strut tower was all the way over. I thought this was odd, but I kept the setting as above.

On the first test drive on the freeway, I started picking up a vibration in the steering wheel that certainly was not there before. It is not serious, but doesn't seem right. I also noticed that it does drive down in corners well but does seem to pull right on straight roads. Could someone look at these numbers and guide me as to where they should be. I am sure the shop will make the changes, just not sure where to go from here. Observations ?? Thoughts??
