Check out the Baer kit for the focus - it uses the same PBR cailper, with brackets to mount them out on 13" rotors. If you're real slick, maybe you can get the kit, minus the cailpers, and then buy whatever cobra set you want. That's my plan anyway. Try the website www.spmotorsports.com.
The mounts are different - the svtf has 3.5" mounts, while the PBR's mount to a 5.25" (I believe). If you get this done, keep me posted.
