Description: The overall thickness of the front lower arm has been optimized, resulting in a dramatic increase in rigidity. Initial steering response, angle maintenance, and traction retention are dramatically improved. While inheriting the angle, stability, and traction characteristics of the "Brass Sleeve Type Wide-Angle Compatible ASTα Front Lower Arm," this model pursues even greater improvements. It's the perfect upgrade model for users seeking aggressive driving. Depending on the type of knuckle you are using, interference may occur. In that case, please adjust by filing down the interfering part. [2 pieces included]
