Urgent Rim Dilemma...please Look!!!

[Wilnutt]

ok...here' ,y dilemma..i'm trying to understand rim set-ups..I have been told that my 71' demon's offset is 0...so on a 15x8 rim..i would be looking at a 4.5" backspacing???now my problem is..i went from a sbp..to bbp....went with ssbc disc on front..and a b-body rear on the back..now the b-body rear is about an 1"-1.25" bigger on both sides....so to add backspacing would i just add an 1"-1.25" to the backspacing??? plus..i'm trying to figure out offset...i'm assuming the more positive the offset..the farther in the rim is?..and visa-versa???

i'm just trying to figure out what rim sizes i would need...i think i would wanna go 15x6 on the front..and 15x8 in the back???will either be a problem (due ot rubbing etc.)

and i want the rear tire to be bigger..give it that old school aggressive stance...what tire size should i go with..with these rims???

if soeone could take the time to PLEASE!!! help...that would be great..thank you...

I got a E body rear in my Duster. Stock with with 15x8
rims. 4 1/2 back space. I have no problem with the tires
rubbing. You shouldn't have any problems either.
I could of even went with a 5 in back space without hitting
the springs.
