Now that I have the car in pieces, I try to replace the parts that I can with something better.

Having reconditioned the calipers, I thought about replacing the bolt on it with something better, like Stainless steel.

Turns out, these screws (M12) are made with extra fine treads (1.25) and finding these proved to be worse then find a needle in a VERY large haystack.

The best offer I have so far: is

4x M12x1,25 60mm length   25,67 Euros

4x M12x1,25 25mm length   28,87 Euros

If anybody knows of any better ideas or prices on these, please let me know. Preferred material is: A4/AISI316 or A2/AISI304

I would not use stainless steel bolts. They are not as strong as the originals and there will probably be galvanic corrosion. Also the washers are very specific. Finding the correct new once will be hard.
I had my brakes and bolds electrochemical galvanized with an gold colored finish. this makes them as new and it looks great.

You are not allowed to use stainles steel bolts for the calibers, if the MoT inspecter will notice, your car will fail the test.

Hmm, after looking a bit closer, it seems that you are correct... http://www.tessco.com/yts/customerservice/techsupport/whitepapers/pdf/bolt_grade.pdf

Guess I'll have to go for some kind of coated ones then. What would be my best option then, considering the roads in Norway are salted more then McDonalds fries....
