    You can grind a little off the calipers if they are hitting the rim/wheel weights. You can't grind as much off them as a D60 Caliper, but can be ground a little. Weird thing is, if the fronts fit, the rears should too as they use the same/similar rotors and calipers.

    i had to grind just a little bit on mine, but not nearly as much as i did when i converted to 8 lug up front. brackets are top notch im very happy, the only thing is that i need a adjustable proportioning valve for the rear because they lock up to fast /forums/images/icons/grin.gif
    in the picture you can see the rust (still need to paint it) from were i had to grind just basically the casting stuff

    Isn't there a prop. valve "mod" that is supposed to alleviate that problem without needing to go adjustable?

    I just thought I recall something being mentioned about taking the valve out or something...IIRC, the Impala SS (newer RWD ones) people do that mod sometimes as well...just mention the Impala folks because you might be able to dig up some info on the mod with that.
