From what i have found out(my source sells Nismo parts and Sway Away parts) the Nismo(made by Sway Away) and Sway Away branded torsion bars are exactly the same. Carlton's Nismo ones are white and so are the Sway Away Powerbarz, I would think Nismo would ask Sway Away to paint theirs a different color if they trully were different. Maybe we can get Carlton to take a micrometer and measure at a certain spot and then have Mike, Kirk or Schlud do the same and see if there is a difference. I know Mike has the Sway Away ones for sure...Kirk, Schlud do you know which branded ones you have?
