The kit included N (front suspension arms) parts are made of a glass filled plastic. These Hop-Up-Option N parts are made of CARBON filled material plastic. By using carbon filled suspension arms you will notice less flex during hard cornering. The use of using carbon filled plastic also yields a part that is lighter in weight compared to the standard part.  

• Lightweight, reinforced parts offer improved handling and the ability to apply a more precise set-up to your machine.
• Includes one parts tree.
