MM Wheel spacers?
 

my stang has a bad case of the tucked in look even with 17's and 275's i think 45mm spacers would make it look aawsome...what do you think? i want it to look like the rear wheels on the 99+ Cobra ...you know how you can see them sticking out a little.

anyway what i want to know is if i put on 45mm spacers from mm will they be way to far out like a burrito blaster?

If they are the stock 17's they will look very nice that way.I had spacers with my stockers and it got alot of compliment's.

they are not stock....my tire size is 275/40/17

i think they are the same width as the stock ones tho, is there a simple way to find out the width or the rim?

what year is your car? Are you using 8" 8.5" or 9" rims?

If you're driving a 94-98 then 1" spacers will be right on the edge of getting rub or not with 275's on a 9" rim. 1.18"=30mm so 45mm will almost certainly rub with that combo. 1" is always enough to look good with tires wider than 255.
