    Falken Wildpeak 255/85/16

    With the setup above, I don't have any rubbing while parked or during normal driving. I was looking in the wheel well yesterday and noticed the UCAs are really close to the tires on both the driver's and passenger's sides (pictures attached). Based on those, is it safe to assume this will become a problem off-road?

    Any good way to driveway test for this? I'm still in engine break-in so I'm not ready to take it off-road quite yet.


    EDIT: To clarify, there is no contact from full-turn either direction. I'm worried it will contact when the wheel is stuffed.

    2-2.5 inch lift with Bilstein 6112/5160s included in the wheelers trail pro lift kit. And 255/85r16 Yokohama Geolander G003 tires.
    Those look like SPC upper control arms, if they are I have 255/85r16 Yokohama geolanders on a trd offroad wheel with no issues.

    Originally I was going to run these with stock wheels and had purchased some but I ended up buying some wheels that have plenty of negative offset to push the wheel out.

    You’ll be fine. As the wheel articulates so does the control arm. Meaning that they will be that far away no matter what position your suspension is in. No need for spacers.

    Thanks for brining this up. I think the issue here may be my ignorance on how the suspension moves under load. When the tire move up (higher, closer to the fender) does it also move slightly out, on a pivot point?

    Here’s an animation from Cambirg but the idea is the same. Notice that the spindle is attached to both control arms (upper and lower). So as the wheel moves up and down, they do too. Your tire physically can’t get closer or further away from the arms. The benefit you have with the SPC UCAs is that you can move the upper ball joint out so the spindle (and tire) gets further away from the UCA. From the picture you posted, the ball joint is at the center of its adjustment so you can move the tire out another 3/4” or so if you move the balljoint (you’ll need an alignment afterwards BTW).

    What do your lower control arm alignment cams look like? It looks like you are pulling a fair amount of camber out with the location of the upper ball joint. You may be able to adjust the lower cams and gain clearance at the upper control arm by moving the upper ball joint.
