    Hmmm this is a new one to me. I have never heard of someone wanting to downgrade their brakes before. I am kind of dumbfounded.

    I have to ask man. If you are running 4" lift spindles and 33 inch tires why are you downgrading your brakes? That isnt the smartest thing to do.

    I dont know if you can bolt on the smaller rotors, but like the previous poster I dont think it would be smart to downsize the rotors. I wouldnt recommend it even if you were running stock tires and wheels.
    If this is an attempt to fit smaller wheels you'd be better off not doing it.

    X3 , you will really degrade your braking capacity since you have drums on the rear. That's why you have bigger front brakes, because of the drums.

    X4, if the factory puts something on a vehicle its the minumum that needs to be there for a reason. That reason would be safety.

    Only reason would be to run smaller rims, 16" for example. '05's require 17" rims.
