My wheels finally arrived after 20 plus weeks and to my suprise the fronts spindle hub hold the wheel away from the mounting surface by about 1/8" (not the width of the hub but the length) thats without the spinner hub in place. The wheels are 17"X9", spindles donor 91 mustang, rotors 1989 Lincoln MkIV 5 lug conversion.
In my case the only fix is 1/4" spacers and longer studs. What is the problem?

Thanks

Denny
