I got a set of BC coilovers that I got from 2J. They have 10K springs and were on my 06 spec from the summer to September last year, roughly three or four months Never adjusted ride height and only changed dampening in the front. These things are stiff! I ended up trading in the spec and this was the only thing I pulled off. I'm in Connecticut, north of Hartford and can text pictures. Asking 800. Feel free to message, I can text pictures.
