So I took it to a Porsche specific shop and they gave me the following setup:

FRONT: Toe = 1,5mm, Camber = -0.6 deg, Caster = +7deg.
REAR: Toe = +2.0mm, Camber = -2deg.

Wih the front toe increased from 0 to 1,5mm the nervousness dissapeared and the car now feels really good at all speeds.
And don't forget that the rear alignment has a marked affect on the cars feel too.
I had it set to the factory specs in the shop's database. Either way, had I kept the car, I'd probably be doing the shocks by about now anyway.

To OP Stilov:

I just ordered a set of KW Variant 1 coilovers for my Mini Cooper, and the Cayman Turbo is arriving Friday after next on a set of H&R RSS coilovers. I'll be autocrossing the Mini next weekend and having a trackday in the Cayman the weekend after and can give my take on the highway ride quality and handling of each of those setups at the end of the month.
