Any help fixing bump steer?

[DrunkenSlug]

Long time teamroxor! I've still got the roxor, still having fun with it (albeit diesel being 6$ is a bummer right now!)

Was wondering if anyone had purchased the BMF SPOA kit? I did and went with 38" tires with some 2" spacers. I find that the roxor likes to wander all over the road now. I've had my alignment done and confirmed at 2 separate shops now. They say that the castor(?) is 0* now because of the lift and its unadjustable?

Whats the fix here. Driving my roxor is a chore now instead of enjoyable haha. Is this what bump steer is that people talk about? It'll drive down the road straight. The second you hit anything it just goes allllll overrrrrr the road. Even small bumps hardly discernible by my eyes metrics

Oh one more for you guys, my ebrake light no longer turns off even with ebrake not set. It's been like that since I lifted it. Checked for obvious wiring under near that might have come undone, nothing I see.. Any ideas? Maybe I smacked something back there or moved something? idk.

I did a Rough Country SOA (5-5.5" Lift) with 35" Tires and 1.5" spacers on mine. I did put a different steering stabilizer on. I did my own alignment and zero'd out the toe. One finger steer to 70 MPH and after that you're fighting wind to 80 MPH, so that gets a little hairy.
Did your kit come with a drop pitman arm? I can't tell by the pic. But that is a necessity with that much lift. Geometry will be off HUGE and it would be turning the wheels to the right on initial bump, then pull left like crazy on the upswing. If you already have that, find out how they aligned it, If they put toe into it, that can throw you around. I try to keep it at 0 Degrees myself, if it feels too lose, give a half degree toe-in, if its still too tight you "can" try a half degree out. Try to avoid toe out at all if possible.
All of this in contingent on having good steering components and wheel bearings that aren't sloppy, of course.
