So i have a 07MCS with HR springs(1.5 inch or so) and 17"x7.0" koni Feather wheels. I'm considering wheel spacers to get my wheels a little more flush with the fenders. I spoke with alta and they recommend going with just a 5mm spacer with the set up i have to prevent rubbing. my question is, has anyone run a bigger spacer with a similar set up and have you had any rubbing issues? im more concerned with the rear then the front. im not even sure if i'll put spacers on the front yet. thank you.
