nismo carbon fiber

[JZNx]

After surfing the web for awhile, I realized that I really like the nismo s-tune body kits. Like the front lips, side skirts, especially the rear spoiler, and rear lips were okay =). But I can't help to notice that carbon fiber manufacturers make similar designs or identical designs. Now correct me if I am wrong, but I thought seibon makes a very similar looking kits in carbon fiber. I went through the fourm and I saw some varies other brands that looked identical to the s-tune kits but in carbon fiber 0.0;;;;;;;;;;;;;;;

Now here is my question, what other companies make similar designs compared to nismo s-tune body kits in carbon fiber? And which are the cheapest? And how are the quality?
Links will be really nice but name will do for now =)

Thanks for helping out =)
