Update:Had my plates back yesterday, so i went to the workshop to install the Formula Dynamics Stainless Steel brake lines.
Well, all i can say is that i didn't expect this improvement by them:Brake feel has become more polite, more soft, and the pedal gives you information about the braking process.
I think that every 3200/4200/GS owner has the worst feedback for those brakes, but this time i think something is different, without big cost.
More feedback to follow, as i had some trouble with the brakes in the afternoon, and i need to replace the fluid again, cause there must be some debris inside, that made the rear right caliper bite the disc all the time, even when pedal released.Happened twice, went bak to the workshop, and it seemed to get fixed, but i'll replace fluid again to be 100% sure.
Now to the emotional part:I drove her after five months, and after all the work i did in winter, what i have to say is that she's back more beautiful, and the front grille refurbishment put some more beauty on!
