These are the same arms that come standard with the Cyclone S. They are more flexible than the graphite arms. This helps produce more traction. I ran these last year outside on low-traction asphalt.

You have to be careful when running the softer arms. The graphite arms will stay true until they break. The "high traction" nylon arms will take a big impact without breaking, but the arm will not be true anymore. It will bend or get twisted causing the car to do weird things. Depending on how the arm gets damaged, it can change your toe, camber, caster and droop settings.

If you run the "high traction" arms just be sure to check to make sure things are okay after a big impact and you'll be fine.
