The 3Racing SAK-CM111A rear knuckle arm is designed for the Cero M Chassis to give a firmer rear connection and steadier handling. It suits those tuning their setup for smoother rotation and repeatable lap times.
Engineered to hold chassis alignment under stress, this knuckle arm reduces flex at the rear and helps maintain predictable balance. Use it when replacing fatigued parts or when dialing in a more stable rear end.
