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 rear arms the chassis can feel more responsive and edgy, depending on the cars setup.


Features:

  • Decrease rear end bite
  • 1mm thick carbon for increased stiffness
  • Can increase durability

Includes:

  • (2) Carbon Fiber rear Arm Inserts
