15's will go good

15" go vintage and even go 14"

NOT STOCK!

personally, i'd go with 13 inch CF48's. truly no bigger than 14 inch though. 15's are nice, but are just too big, i feel.

anything between 13 to 15

For a car the size of the Civic, I would say 13-14 max. You don't need big brakes or any additional rotational mass. Plus, 13-14 would look awesome.

in theory your tires should be the same rolling diameter so lowering the car more does not make to much difference..

i think 14s would be good for your car something mesh and dished with the mesh colour dependent on your taste and car colour,

the ride height well thats up to you and how much you want to push the rules in your respective country

Yes.
