    SKU: KTA252 Benefit Note:
    These Whiteline front lower control arms feature high-quality alloy, which offers considerable weight saving over original equipment quality arms. The reduction in weight of the arm, which is partly unsprung weight, brings the similar benefits to a light alloy wheel. In addition Whiteline has engineered significant geometry gains with -0.3deg camber and +2.0deg caster improvements into these arms to optimise wheel alignments settings for street and track performance. Caster increases dynamic negative camber on the outside wheel whilst turning, offering more grip without introducing the tyre wear associated with static negative camber. Furthermore the increase in caster improves traction and increases the self-centring effect of the steering. Throw this altogether and the small change in additional caster improves the front-end grip and handling considerably. Whiteline's rear mounted bushing combines the superior mechanical properties of synthetic elastomer formulation with high quality sealed bearing assembly permitting smooth movement of the arm 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.

    SKU: KTA386 Benefit Note:
    Complete replacement control arms featuring Whiteline Anti Lift Kit that are primarily designed to improve traction and cornering grip under power. Increasing static caster to both front wheels. The special low compliance bushings reduce caster wind-back and maintain tighter tolerances between static and dynamic alignment settings. The additional caster coupled with the firmer bushings serve to dramatically sharpen initial turn-in response - forcing more consistent alignment angles through the corner due to the reduced bush compliance.
