These front lower control arms feature high-quality alloy, which offers a considerable weight saving over original equipment quality arms. The reduction in weight of the arm, which is partly unsprung weight, brings similar benefits to a light alloy wheel. In addition, there are significant geometry gains with these arms to optimize wheel alignment settings resulting in dramatic improvements to steering precision, most noticeably reduced 'toe-change' during hard cornering, creating impressive turn-in ability! The more positive location of the arm through the range of suspension movement and gains in alignment geometry ensures the car feels more responsive and engaging at turn-in.
