Bbs rs build... Help!

[Edirtyy808]

So I bought bbs rs faces Off of a Porsche. I believe it was 012 and 013. Not too sure gotta double check. But the original specs were 16x8/9 +11 all around. But because I only have the faces, I'm not sure what size inner barrel it came with. So my question is how much inner barrel can I have before I hit anything in the front and rear? I know the most backspace you can have for a 16 is 5.5 front and 6 rear. But I want 17s. So I'm tryna find the most backspacing I can have. And what size inner barrel will achieve the most backspacing I can have.


Thanks.

I have late model, also on coilovers, 2 door.

+11 offset is too close, I believe if you use adapters you're going to poke way out.

I'm getting 5x130 adapters in 18mm. But how much inner barrel can I have? I can adjust the poke by getting less lip. I only have the faces no lips or barrels ATM.

So I believe you bought my faces of my old bbs rs. I ran 20mm adapters all around. I believe the barrels were 5 for the front and 5.5 for the rear.

I was running et-9 all around, cleared struts fine, just need a bit of a pull....

Yeah, I have your faces. Thanks for the info.

I was thinking, if I get 7.5 inner barrels, and 25mm spacers, it would be like running a 6.5 inner barrel, but you have to factor in the backspacing. That's what I don't know how to do. I'm just tryna figure out the most inner barrel I can have, and I'll prolly be running adapters anyway.

Anyone??

I have only run 15" RS's but on most of the 15" centres you cant run a 6" barrel without a 3-5mm spacer, so i doubt you can run a 7.5" even with a big spacer...

You can use www.willtheyfit.com and then use 16x9 +12 as a baseline as this is a known common spec that people run on the front with no issues (16x9 +15 with 3mm spacer)

I want a 7.5 inner barrel + .5 face + 1.5 lip= 9.5 rim. But I don't know the offset because I don't know the backspacing. I dont know the backspacing because I don't have any barrels or lips, I only have the faces. Can someone help explain if I can fit a 7.5 inner barrel in the rear? I will have an adapter in any size that will help me fit a 7.5 inner barrel.
