If I keep the 14mm and I replace the sutds (which seems easier to hammer them on a table) will the 66mm be to long or is just perfect (I have the stock closed but)
also considering: what if I add the 7mm+14mm spacers together?

One thing to look at in rear are your wheels.....my Fuchsfelge wheels have pockets between the stud holes - I think for lightness reasons - but it allows the studs that hold on your adapter to protrude a little into the wheel centre boss. I have no problem with my 32 mm spacers and the retaining nuts/studs for the adapter are fairly close to flush with the wheel mating surface. Methinks your retaining studs my stick out a little
In terms of your front, I just measured my front stud engagement with the 21 mm spacer and 66 mm studs. The stud protrudes 19 mm from the Fuchs mating point so that is the thread engagement I have and very truthfully speaking, I like full engagement especially with the aluminium stock nuts I use.
I also measured how deep the threads are on the stock Porsche wheel nuts and it looks to be about 28 mm before the stud bottoms out in the nut.
So your stud can be (based on my experience) - 9 mm longer than my 66 mm's and still work.
If you went to minimums, with 21 mm spacers and using my practice of one full diameter of engagement - so that would be 13.5 mm or 5.5 mm shorter than mine, which implies the shortest stud you can use - with Fuchs wheels - is 61 mm or so.
If you use 14 mm spacers - 7 mm thinner than mine - then your studs could be as short as 54 mm and still have one diameter of thread engagement.
Like I said, I don't like minimums, but my stock studs measured 46 mm shank length (not including the head) which makes them too short for 14 mm spacers and even a little short for 7 mm ones.
Personally, I would say switch out your studs, feel and be safer.

PS - here is a gratuitous picture of my project which is still on the building stand. Just doing upholstery and then engine build and then on the road. Probably does not help you as the car is not sitting on its wheel. s
