Correct Offset April 08, 2006, 05:49:15 PM Okay i posted awhile back in the steering/suspension forum about purchasing some cobra r's for my '88 bird. well long story short, im stuck with 3 17x8's and 1 17x9. obviously the 17x9 isnt going to work and im workin on it....lol. but two of the 17x8's say on the back, 17x8 J +15 while the last one says 17x8 J +30.now my question is which size do i need? or i guess i should say which size will fit? the +15 or +30? also, what offset are the cobra r's straight off of the fordracing website?as soon i can find this out, then i can hopefully figure out the rest of this nightmare.....
