I'm sure your English is much better
than my Spanish/Portugese, no worries
on that.
I just measured the stock 4 door coils,
about 14mm wire, or 9/16" if you prefure
SAE measure. When you go longer on a coil
(more coils) the spring rate gets softer, so don't
go smaller wire and longer, or you will get
a saggy front end.
I got plenty of flex from 3" coil spacers and
some 3" extensions for the front struts, still
running the strut spacers, but the coils I have
added some sections of 4 door spring, now
with the wider front wheels I wish I had used
the whole 4 door spring, and added sections
of the 2 door spring.
For your information the
front 2 door spring rate is about 450 PSI and
the 4 door front spring is about 500 PSI, this
might help you to get another spring that is
heavy enough to give you the lift you want
Good Luck
