JBA uca's and 285's question

[xcalbr2]

Who has successfully run 285's on 2.5"+ lift with JBA UCA's?
Looking for successful setups and wheels selected without using spacers.

Factory Trail wheels, 17x7.5", rub with 285 wildpeaks. Rubbed just slightly on the JBA arms only after the fender tuck and mudflap removal.
I know JBA suggests 17x8.5 with 4.30 backspace or a 17x9 with 4.50 backspace but looks like 4.30 backspace will stick out and require quite a bit of modification.
Thanks

I am running JBA UCAs, 2.5" lift on SCS Ray10s and 285 RG's with no rub at all.

please post wheel size when responding.

Looks like the SCS Ray 10's are 17 X 8.5 4.30" -10mm
Do they stick out much? How much modification was required and do you have any pics? maybe down the side etc.
Thanks

Pretty flush. slight trimming of front bumper and that was it. Clearance is great.

I was also pondering this as I get ready to start making suspension purchases.

I'm running FN pros so I'm not sure if they'll work well with the jbas. Didnt want to go with SPC because of all the issues with them.

The FN pro wheels have these specs:
Diameter: 17"
Width: 8"
Offset: 0mm
Backspacing: 4.5"

Had to BMC as I was rubbing on full turn reverse. The point I circled in the picture is where you will get rubbing. I could probably run 295s with this set up, but nothing larger because I will probably rub on the JBA UCAs.

The newer SPCs have not had any issues that I am aware of. There was a recent topic about this. No body chop with my SPCs, 285s, and SCS wheels. All 4Runners are different I hear.

wow that looks like about a 1/2" inch of space

When did you purchase the JBA UCA and are they the 7.0 set?

I ask because i have a similar setup and had issues with my JBAs hitting the coil on my Bilsteins with Toytec 521600 Springs at full drop ( during wheel removal). I have 285 70 17 Wildpeaks, JBA UCA and SCS RAY 10s.

I heard they where going to design a new UCA with a higher caster. I pushed mine in Spring 2019.
