Agree with these guys. You're definitely over-centering, getting "stuck in the pocket" which is causing the violent shaking/steering chatter.

Wisefab should be able to help you out and give you the list of basic requirements to adequately run WF. Per their website, they sell a kit that moves the rack forward 46mm for better Ackerman curve; see here: https://usa.wisefab.com/nissan-s13-s...relocation-kit
