I've been definitely contemplating this. Got a buddy on e46Fanatics that's going to try and finalize his installation this weekend. Gonna see how it looks on his first (have to be video cause he's in NY state).... My project this weekend is front brakes.... clean, replace rotors and pads, rebuld calipers and paint, then bleed...... paint colour up for discussion.....
