    Any idea if the CTS-V calipers will be able to run a 20mm rotor?

    Several people now have approached me and asked me to make some rear brackets. I'm slow to get things done now, but I'll take a look at it (along with a fun twist )

    You can either run the adapter calipers that bob posted or KNS sells a thick set of brake shoes to make the WRX parking brake work with a sti rear rotor. That still limits you to a 20mm thick rear rotor. I've been trying to find a piston parking brake that will fit a 30mm front sti rotor but haven't found anything that will support something that large.

    I'd like to see if the wilwood mechanical caliper can be mounted for parking. It can take up to a 20.5mm rotor.

    Should work just fine with the sti rear rotor but not with the front like hobby racer did.

    If you want a parking/emergency brake that would work with the wider STI front rotors, you could use one like this from wilwood.

    That would work would just have to run a hydraulic hand brake

    What year is the Legacy brake disk, and is it only 4 wheel studs?

    Ah! Hobby Racer! What size are they?* I have Stoptechs that are 12.9" and they fit inside my 17 inch Wedssport TC105N's .
    *I've been plowing snow for five hours and feel too lazy to search the internet!
