I try and research before asking but at this point my eyes are crossed. Currently using 5100s for a 2" level but want to move up to 3". Also running 22x10 -18 with 285/55s.
As I'm looking to move 3" I'll be at that limit of needing UCAs. I had my eyes on the cognito kit but started to read that some have issues with tires rubbing the UCA. Obviously not ideal.
I figured out my wheels have a 4.79 back space and the cogs need 5.75. I asked them if would work and they gave me the company line "abt this is our recommendation" I spoke with another rep and they said I would need a 6mm/.25" spacer. As my 285s already stick out a good bit, the last thing I want to do is push them out further.
Compounding the issue, I just bought new rims and tires two weeks ago. So replacing those is also out of the question.
So when discussing backspacing, if it says works with a 5.75 backspace does that mean it has to be less or more than 5.75 in order to work? I thought since I have -18 and theres quite a bit of room from the stock UCAs to the falkens currently, I figured I'd be good.
If the cogs don't work out, are there any other quality UCAs that would work with 4.79 backspacing?
