I have not heard of a brembo setup for the vx. As for an upgrade I have the stainless lines on mine which everyone here says is a very good upgrade. I cant tell you how it was before & after because they were on when I bought it, but I am very happy with it now. The only thing I plan to really do is go with ceramic pads soon.
