    Boris,
    Service department found the rear subframe was not perfectly centered when mounted at the factory. Service did submit a claim and told me that the issue is known to Porsche though not well documented. Long story short, after 3 days of messing around trying to improve rear negative camber, I still wound up with ~ -1.35* each side and a hair of toe in at factory set ride height. The limiting factor is the rear camber link, just not long enough to allow any more camber with the proper toe. Combined with my front camber of -2.1* (with 8mm shims) and zero toe, the car turns in nicely at autocross events and so far (4 events) tires look to be wearing ok. Decided not to lower the car as its already scraping on the street and I can barely get it on my trailer with 8' of ramps. The dealership service department has set up 3 GT4s with aggressive alignment specs and thats about all they can get out of the rear in stock configuration with maybe 1-2/10s variance.

    Hi 5500,

    Did you solve your alignment problem? I'm experiencing the same alignment issues with my GT4 as you have encountered. I could only get -1.2 in the rear and the toe is barely within spec.
    My car does sit a bit higher than what I saw other people reporting. Lowering the car would be my next step, but I wanted to check if there is another issue or solution I should be aware of.

    BTW my car is late February 2016 build.

    Thanks,
    Boris
