    13 inch rotors from GMT900

    Now from what I understand moving to a 17 wheel the GMT900 rotor will work. If your switching over to a gmt800 anyway get the bigger brakes because they make that much difference from a gmt800..so jumping from a gmt400 to a gmt 900 is what you should do if you want to change your rims. Here is...
