okay guys so i am set on getting a set of juicy 7's. so that little question is solved, but here is the problem that i am having. i can save weight, and money with going to a smaller rotor in the rear (aka 7" rotor). i know that is great but i dont want to sacrafice stopping power just to save money and a little weight. so those that have run the 7&8" setup on a set of juicy's please help me. thanks guys it is much appreciated.
