Do I need to run bumpsteer adjustable tie rod ends with the AFX spindle?
No. The AFX spindles were engineered with bump steer in mind. We designed the steering arm attachment points lower than factory to improve the bumpsteer for the F body cars. By re-using the factory F body steering arm, we were able to bring bump steer down to nearly zero. Because the A body cars are front steer (and therefore require the steering arm holes to be raised from the factory location) a new steering arm was designed in-house to cure the issue. Bump steer correcting tie rod ends can still be used as an additional tuning method, but the install should be measured afterwards with a bump steer gauge to make sure that the issue was improved, and not worsened.
