About this part

Insert Overview:

Adding carbon arm stiffeners to the MBX8R increases arm rigidity, reduces flex, and provides a more consistent and predictable handling response, especially under high loads or aggressive driving. By minimizing flex in the front arms the chassis can feel more responsive and edgy, depending on the cars setup.


Features:

  • Increases front end responsiveness
  • 1mm thick carbon for increased stiffness
  • Can increase durability

Includes:

  • (2) Carbon Fiber Front Arm Inserts
