well its been a while since one of these questions has been asked, so i thought i would renew everyones minds so they dont forget whats needed :P

ive got a 66 mustang. what backspacing do i need to run a 15x8 wheel?
the dodgestang chart didnt help...
if i could just get a straight answer that would be awesome

 

4.5


and its on the chart

 

Try this one:

 

on that chart it says 4.5 but for the rear only, will it work on the front too?

maybe im too stupid to understand the dodgestang chart.... haha

 

There is this entry:
15x8
4.5
275 60 15 Rear / 205 65 15 Front


The best fit for an 8 inch rim is 4.75 bs but you can't run this in the front with a 15 because of contact with the upper ball joint. That is why you can only run a max of 4.5 in the front. I can feel confident in my statement because the information on the chart is from a real person with a real car telling me all the details of what they run. Also 16s have the same exact issue as 15s which is why if you pay attention to the chart all the people with 16x8 don't go over 4.5 backspacing...and a couple of those entries have photos.

 

17's have the same issue as well, don't they? I thought 18's were the smallest wheel that will clear some ball joints, depending on the arm/joint that's on it.

 

17x8 with 4.75 bs fit on just fine. Had them for years on Mustang Plus OEM style replacement upper arms.

 

awesome! thanks dodgestang!

 

any chance of goin wider than a 205 on the front? like a 215 or 225?

 

The concourse with the 3bolt ball joints?
