Team Associated RC10B6.3 FT Rear Suspension Arms 73mm, carbon fiber
- Lightweight - Approximately 12% weight savings over "hard" material.
- Extreme Rigidity - More predictable handling in high traction applications and increased vehicle stability in fast corners.
- Improved Durability--Significantly improved strength over "hard" option parts.
These will work on the B6.1 if you use the 2mm shims #31389, because the arm is narrower at the inside hinge pin area. The shock mounting holes will be okay and the hub carrier will be the same.
