I'm wanting to get some rota D2 wheels in 18x8 for the front and 18x9 for the back... which offsets would be the best to run?

for the 18x8 there is +25/+30/+35/+42/+48 in 5x114.3
for the 18x9 there is +30/+35/+45/+48/+50 in 5x114.3


i tried to download jimlab's xls file for the wheel sizes/offsets but i couldnt get it to work.

 

If it were me, I would run the +48 in the front and the +45 in the rear.

 

yea that sounds good for the fronts -stock size and almost the same offset. i suppose that would be just about right in the back too...1" wider and 5 more mm, since the stock wheels sit in about an inch and a half.
i just wish i there was a way of seeing the wheels with the desired offsets before you buy them...

 

Not exact, but here's +43 all around:

ok now i'm wondering about 8.5 front 9.5 rear... just subtract about 10mm from the 8" and 9" offsets?
