Steering angle uneven S13

Got around to installing all of my go - sideways parts and ran into a little issue after install. I have one full rotation of my steering wheel to the left, and one and a half rotations of the steering wheel when turning to the right. Steering angle to the left is approximately stock lead wheel, and angle to the right is approx 60-70 degrees lead wheel. Turning either way though, there is little-to-no ackerman, which is the way it was tuned intentionally. When turning to the left the tie rod makes contact with the lower control arm after one full rotation of the steering wheel.
Car has been aligned.
It's 1am and I figured someone on here might have an answer that'll help....

Angle mods:
-Modified knuckles
-25mm extended/boxed lower control arms with bump stops removed
-Isis high-angle series tension rods
-Isis inner/ outer tie rods
-GK TECH steering rack offset spacers

you need to re-center your steering rack. Put it in the middle of it's travel, reinstall the wheel in the middle, and re-adjust the tie rods.

Did that. For some reason the tie rod on the left is hitting the control arm sooner than the one on the right. Disconnected the outer tie rods to find the center of the rack, then re installed. Centered. And still have the same problem.

Well you're doing something wrong then, or your rack has shifted off to one side...

Going to trouble shoot everything this week. Just wondered if anyone else had this problem. I think it's the GK offset spacers. They don't sit perfectly horizontal, one sits up a little and one drops down a little. So I might take them out and notch them to be in the correct position. And go from there
