first off i would like to say hi. im new here and this is my first post. hopefully i do this right. \n\nim wondering if 11.7 stock rotors would be any better than cross drilled and slotted 11.3 rotors for a 66 galaxie. would .200 per side make much difference?\n\nthe reason i ask is both rotors are pretty much the same price.\n\nthanks for any help.
