Afternoon all
My 981CS has been pulling to the left so I took it to a local well regarded and recommended local Porsche specialist for an alignment check and adjustments if necessary.
The new settings are in the attached photo (apologies for the mis-alignment!!) and I was assured all was well following their subsequent road test of the car.
However, upon driving it still pulled on different roads, swapped lanes on a dual carriageway and still needed slight pressure to the right to keep the car straight.
I have been assured the settings in the photo are within factory specs but my question is whether they should be more equal ie should the right and left settings be (more) aligned and are these disparities enough to make the car behave in this way?
I don't think a brake is binding and everything else appears ok.
Would be grateful for some advice.
Many thanks

Yeah that alignment isn't great...

You have uneven toe in the rear, uneven toe up front, a 20' caster difference (acceptable but not ideal), and the front and rear camber is different side to side.

This combination of things will certainly make it feel odd when driving

I'd take it somewhere decent and have them do it properly

Thanks guys.
I've taken the car out again tonight to make sure I'm not imagining things and it's just not right. I did question the unequal readings when I was given the print out but was assured they were fine and within tolerances - obviously not the case as it felt wrong within 2 minutes of leaving the workshop.
This has surprised me as it conflicts with the professionalism of the staff, the reputation of the business and the wide variety of newish and old Porsches onsite today.
They have said I can take it back and they will get it right but how difficult is it to set it up with equal left/right settings?

Does anybody have details of the factory settings and/or copies of alignment for a non-PASM car?
Many thanks

Evening all
Thanks for the further replies.
It's interesting that some of you think the alignment is poor and others think it's acceptable.
The car previously tracked straight but started pulling to the left (my wife swears blind she hasn't hit a pothole!) which is why I took it in. The alignment hasn't fixed the pulling - the tyres are fine and according to the indie which performed the alignment there is nothing visible which would indicate anything otherwise.
It pulls to the left on different roads and goes to the right when the steering wheel is held level.
My problem is that I don't understand the effect that the differences in the left right settings will have - in my mind they should be more equal than they are.
Anyway they're going to take another look and I'll mention the points raised here so hopefully it will get sorted..........
