Im not entirely sure, they wheels were originally on a Fiesta ST and sat perfect on that, so im sure somebody will know. I used proper bolt on spacers to use them on the escort. Dont get me wrong though, i could have not used spacers, they wheels just sat a little further in thatn i liked thats all. The proper bolt on spacers can be bought too if required. I have no wheel wobble or any vibrations well past 70mph.
