The only thing I can tell you about Gold-Line springs is they sell them at my Honda dealer --- largest Honda dealer in the region --- #3 in America --- and like #10 in the world --- whatever. These guys can sell anything they want, but the parts manager swears they are the best. Of course, this is all anecdotal, so it doesn't mean squat. They look okay, but I've never personally known anybody that has run them except Jody, the parts manager dude at my Honda dealer...
When I'm trying to sort these kinds of things out in my mind, I like to search a place called Modacar. They are a one-stop shopping place for imports. If they carry something, you know it's good --- actually good, better, best based on price. This is their spring section for CiViC's. If it's on this page, you can bet it's okay...
