Aftermarket UCA wheel fitment question

I am looking at purchasing some camburg, icon, or Total chaos upper control arms for my taco. On their product description, they say it fits with stock wheel sizes. My question is if they will fit with a 15" wheel or not? Trying to cover my bases before purchasing...

 

I don't think the diameter matters, it's the backspace and offset that determines whether the wheels will rub or not.

 

do you know what the minimum backspacing required would be?

 

I don't believe aftermarket upper control arms will cause rubbing on the control arms if that's what you mean, as far as gaining a small amount of travel, you may rub the inner fender wells, fenders, or bumper if you run 33's and a safe go to for back spacing is usually 3.5"

 

also make sure the 15's you're getting don't interfere with the calipers. some are known to rub. reason for 15's?

 

youl have more clearance with a uniball actually.

 

I already have the 15"s. I belive they are a -19 backspace but i could be wrong.
