    1/4" Spacers?

    Well, I've got a whopping total of 2 miles on my car now and if anyone remembers from the below thread, I have a problem with wheel fitment on the d/s, although the p/s fits fine. I have attributed the difference in fitment to the difference in factory and re-pop fenders.  The d/s rubbed a little bit just coming in and out of my driveway, so I need to do something sooner than later.

    My wheels are currently 17x 7 with 4.25" backspace and a 235/45/17 tire. I am going to switch to a 225/45/17 tire and am going to change the backspace on the wheels. So, here is the question...  should I go with a 4.5" bs or, to make sure I have no clearance issues, go with a 4.75" bs and then, if I have the room, use a 1/4" spacer?

    Thoughts on using spacers?

    Avoid spacers since you have the opportunity to do it right, in the first place. 
    17x7 with 4.5 bs will fit great.

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.

    Agree with avoiding using a spacer.  Suggest you check the clearance to the as-is inner fenders which you can use as a guide for how much more wheel backspacing you can handle.

    I had spacers on my 66 with 2000 Mustang wheels 235/45/17 tires b/s unknown. The car drove like a Buick Electra. I had the fronts narrowed following the specs MS used.

    I have extended studs all the way around and run 3/16" spacers (a bit thinner than the ones you are considering). I got the stance I like.
