I have seen a graph that outlines the specs of each one, maybe someone could find it and post it. After looking over everything I decided I wanted the GC full coilovers, but due to pricing, I am going to go with the Eibach Sportlines. That's my choice as of now, nothing is sealed in cement until I save and pay.
There are lots of options out there and lots of opinions on each one. You might come to a different conclusion than I did.
That graph was a big help, but I don't where it is.
Also people who have owned the product and taking in their reviews. Since I haven't dropped my 5 yet, I got none for you.
