Camber setup issues

I've got my GT4 this week and asked the dealer to max out front and rear camber without shims before delivery. Picking up the car, they showed me the alignment report and I was shocked. They couldn't even get to the low range of the standard specifications on the left side of the car, front (-1.22) and rear (-1.08).
They told me they checked and there was nothing wrong with the suspension; and that I would need shims to get to the values I wanted.
Has anyone experienced a similar scenario? Would there be something wrong with the suspension that they didn't detect?

Actually the values are 1°22" and 1°08".
I'm taking the car to the dealer next week so they can get it done properly. Now I'm only asking to get it to standard specifications, and I'll see what I'll do from there.

Tried two different manufactures of computerized racks. I'm going to track tomorrow, see how it feels, and get it back onto a Hunter next week. If we still can't get it, maybe a trip to dealer or mods are in order.

Dealer called me back today. They contacted Porsche Canada and according to them (presumably an engineer, I'm hoping) it is possible that it can be difficult to get spec camber values in new cars (I ask myself if the suspension gets more compliant with time) and the use of shims may be necessary even to get to base spec.
I'm taking the car back next week to get it done, all covered under warranty, parts and job.

I know this will sound silly but how does the Tarett race camber plate allow for more camber? The factor mounting points look to have quite a bit of allowable movement. When looking at the Tarett race camber plate it looks fixed when comparing the mounting pins. Therefore, how does this kit allow for more camber?
We are finishing up a new build that now includes additional caster as well, close to what the GT4 plates have but with added camber too. Adding the casted required reducing the camber increase slightly to about -1 deg over the OEM plates. The overall camber and caster increases are similar to what Porsche Motorsport did on their RSR plates.

Your basic alignment specs will depend on the :
Ride Height
Amount of Fuel
Weight of the Driver
Tire Preasure
How leveled the Alignmet Rack
From my experience the RT side on Porsche always has more camber adjustment vs LT side.

Our camber plates add about -1.1 deg of camber compared to both the GT4 and standard 981 plates. This is accomplished by shifting the strut location relative to the three mounting studs.

This is exactly what most DE guys need....

i am not a chassis guy. but my suspension tech is really good. the issues i hear over and over, rake, not enough camber achieved, camber plates, caster.... if your alignment tech is indeed good, he will get the parts needed and get it right. its' not just camber, toe etc etc. it's all tied together and depends on the driver too.

So this means that the extra camber comes from moving the top of the wheel farther inboard, correct? If so, wouldn't we be back to the discussion of the ideal way to achieve camber being to push the bottom of the wheel more outboard instead, as is accomplished with shims, since that both increases camber and track width? I remember reading a post somewhere I think from BGB that this is why you want to start by de-cambering the top mount, then shim as much as is feasible, and only then add camber via the top mount. I understand that shims can only be taken so far and camber plates would allow extra camber even on a car that's shimmed out, but what is your opinion on which strategy is best to achieve a modest camber increase?

Here's a dumb question (and most of mine are). Say, I go to a Porsche-centric shop, and need shims in order to get the camber that I want. Is that something that they're bound to have on their shelves? How do I get the right thickness shim if it's variable car to car?
