thanks for the response.. in the brembo supplied directions.. ( i know they are generic) but they state to refasten the rotor with whatever was used on the stock setup ...if the directions would have specifically said to only put it back with one to allow this expansion/contraction i would have certainly did it.. but who knows..

it just seems everytime i do a mod it is a little different than what the other people have experienced .. which concerns me at times..
