I have a Whiteline H-brace which is pretty light and fits well.
I got to hold a Cusco one at the same time, and the Cusco was amazingly light, but more expensive.

So I have Whiteline H-brace, F & R sway bars, rear strut brace, ALK and a carbon STi front strut brace.
Made one hell of a difference once it was all in.
