Using these Voodoo13 rear traction arms is simple. First, remove the original equipment arms from your Nissan 370z or Infiniti G37. Then, install the new adjustable traction rods in their place. You can adjust the length of the rods to change the bumpsteer curve according to your needs. When you're switching from the original traction rod with a rubber bushing, be aware that the 7/8″ heim in these new arms may make some noise. As for maintenance, regularly check the heim joints for any signs of wear or damage. Keep them clean to ensure the self - sealing and self - lubricating features work well. Also, inspect the brackets and spacers to make sure they're still in good condition. If you notice any issues, it's best to replace the parts as soon as possible.
