      So I have 17x8 et43 and 17x9 et40 BBS RS's. Im trying to sell 2 barrels and 4 lips to make them not staggered however it hasn't happened yet and I was thinking if I could just run staggered on AWD and how would I do it.

      I'm just confused about the offsets and how I would get it to work. I would like to keep the 17x9 et40 and run them in the front with a 8mm spacer to clear my brakes, then I would get 1.5" lips for the 17x8's and that would make them 17x9 et? im sure I would have to run a spacer in the rear to make them the same offset right?

      Any help would be appreciated.

      OK. I'm going to address the second question first, changing the wheels up.


      Changing the 17x8 et43 to something else is easy. I'm going to do the best I can, since you didn't tell us what kind of RS's these are, or their current lip/barrel specs... I assume these are 320/321? The 320's are 17x8 et43 5x114.3, so they have a .5" lip, 7"barrel, and the face accounts for the other .5".

      So you wanted to add a 1.5" lip to these.. Keeping the 7" barrel, adding the 1.5 lip makes your wheel 9" wide now, but the offset drops to 30 (30.3 actually).


      To answer your first question, wheel width doesn't matter with AWD systems, the overall diameter is what must be close... Now, it says in your profile that you have a subie, so I don't know if they are as sensitive as VW or less, but I would have to assume the same principles apply...

      Thanks for the response. They are 320/321. So 17x8 are 7" barrel and .5" lips the 17x9s are 7.5" barrel and 1" lip.

      The thing is I just dont want to spend much money making them a square setup if I can run the 17x9s in the front and get a 1.5" lip for the 17x8's. Then I would have 17x9 all around but different offsets. Thats what threw me off. And the fact that I need to run an 8mm minimum spacer up front to clear my brakes.

      So if I kept the 17x9 et40 in the fronts and added a 8mm spacer, that would make the offset et32?
      Then if I got 1.5" lips for the 17x8 et43 that would make them 17X9 et30, like 87vr6 said.

      So I would have:
      17x9 et32
      17x9 et30
      and I could run the same tire all around. That would work for AWD right?

      There are many things you can do. I think you're a little confused about things...


      Like I said above, it is the overall, or rolling, diameter of the wheel/tire combo that matters for most AWD systems... It doesn't matter if you have 17x7 et50 on the front with 17x9 et10 on the rear so long as you have tires with similar or same overall diameters...

      Like your current wheels... I don't know the offset requirements for your car, but if you ran a 245/40/17 on all 4 wheels, the AWD would be happy. It doesn't know that two of you wheels are 9" wide and two are only 8".

      It all depends on what you want, do you want a staggered look with the lips, tires, etc, or not?

      If you want all 4 wheels to be the same, then make the 17x8 into 9s, and put the same sized tire on all 4 wheels and you're good to go.

      Yes, adding a spacer makes offset drop. Well, until you go past 0, then it adds... But you know what I mean... Adding a 10mm spacer to an et40 wheel makes an et30 wheel...

      Definitely confused on things lol but that helped a lot.
      The only other question i have is how did you get the offset at 30 by adding a 1.5" lip?
