i have some bbs rs and the specs are 15x6.5 et +32. i would like to add some 1.5" lip, what is now? link to see the difference for bbs rs?

 

do you want to know what the lip size is now? or? please be more clear w/ your question.

 

the size of the rim and et

 

oh. so you want to know the offset after you add a 1.5" to a +32 15x6.5... got it..

it will for sure be 15x8 and i would estimate at about +12 offset

i based it off of this: https://www.rsracing.com/images/tech-wheeloffset.gif

i looked at the specs of your 15x6.5 +32 and then went down to 8" which is 1.5" more and came up w/ +12 offset w/ the same backspacing as your OG rim specs
