'99 Q45 Installed S13 SPC front tension rods - Concern?

[nismopc1]

Alignment was performed a few weeks ago and they stated caster was out and unable to adjust. Vehicle pulls to left even though the rest of the alignment in within range. Pulled before alignment and after.

After some research, I purchased the SPC Performance front tension rods for a S13 and installed them yesterday. Slightly concerned about the length of exposed threads. Appears the S13 stock rods are much shorter than the FGY33 stock rods and that is reason for length I had to extend the SPC rod.

Thoughts? This is picture of drivers side since it is the longer of two rods...
