Basically it is similar to a conventional passenger car balljoint, in the fact that it is a circular ball that rotates in a housing fixtured to the control arm.

This rod end, since it is threaded would allow for the rod end to be moved in and out in relation to the control arm end to hypothetically adjust camber. Camber is conventionally adjusted from the top via camber plates.

That said, I would highly suggest not adjusting these out, since rod ends are not designed to be loaded in bending. The rod end sticking out of the control arm is a single shear part loaded in bending and tension/compression, not what I would call typical engineering practice. I would caution that the rod end should be screwed in as far as possible to reduce bending moment and shear on that rod end shaft. I should also note the higher the hub is spaced upward from the rod end the larger the bending moment becomes on that bolt. Care should be used when spacing these as typical bolts are only designed for tension.

That said best of luck to those who use these, I am very interested to see how these hold up. It should be made clear to anyone who purchases these that those rod ends should be inspected very frequently, as should the bolts parallel to the hub. Check the rod end threads for shear/bending fatigue, and the eyelet for deformation, which can lead to seizure and failure of the rod end, resulting in the bottom of the hub parting from the control arm. Also as I have mentioned before, bending moments are largest under braking, arguably the worst point for the wheel to become disconnected from the vehicle.

Nice.

Awaiting the pics...
Is there testimonials out there regarding how these hold up on the track and how they increase the front end grip?

Ask Happynole, He has the only set so far on his NX and now on his B14. I will have 5 sets done tonight and ready to ship.

Meavans, yours are shipping either today or tomorrow in the AM.

I did make an extra set of the tubes so if these sell well I can keep making them.

If you want the rear Delrin bushings then the balance would be $335+$10 for fees. If you dont want the rear bushing then the price is $310. Thats with the 20% you sent me.
