Need advice on running 16" Fj wheels with TBU!

What size spacers do i need to be able to run these wheels with the TBU? And i'm assuming i will need 4 spacers yes/no?

Please provide a bit more details on those wheels. Backspacing \ Offset details? That's what really matters. What size upgrade do you want to do, There's two different sizes. I have the smaller of the two and they fit on my wheels fine. But not the larger ones I believe. That will be changing soon!!!:reddance:

You're right and i apologize for not providing enough details. Wheel specs:
16x7, +15mm, 6x5.5 (6x139mm), 106mm bore.

Upgrade size: I'm upgrading to the 231mm calipers. Thanks [MENTION=28808]psraff[/MENTION]!
