These Whiteline front lower control arms feature high-quality alloy, which saves a considerable weight 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, Whiteline has engineered significant geometry gains with +0.5deg caster and anti-lift improvements into these arms to optimize wheel alignment settings for street and track performance. The caster increases dynamic negative camber on the outside wheel while turning, offering more grip without introducing the tire wear associated with static negative camber. Furthermore, the increase in caster improves traction and increases the self-centering effect of the steering.

 

Throw this all together, and the small change in additional caster improves the front-end grip and handling considerably. The lift and dive geometry change enables the suspension to work more freely. Whiteline's rear-mounted bushing combines the superior mechanical properties of synthetic elastomer formulation with high-light alloy housing boasting anti-geometry characteristics permitting smooth arm movement as the wheel moves up and down. Complemented by a front bushing utilizing an oversized heavy-duty crush tube, 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, mid-corner, and corner exit.
