    SKU: KSB599 Benefit Note:
    You can never have too much chassis stiffness. Weight aside, the more the better. Chassis bracing maintains alignment angles and spring rates by greatly reducing body or chassis flex. In fact, it helps every component in the suspension system do its job properly and you can feel the difference through improved turn-in, sharper steering response along with greater steering feedback.

    Available for Preorder. Ships within 4-6 weeks.
    SKU: KTA289 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 +0.5deg camber improvements into these arms to optimise wheel alignments settings for street and track performance. 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: KLC32 Benefit Note:
    The kit utilises a high tensile extruded alloy link fitted with ultra low compliance synthetic elastomer bushings. Critical hardware is replaced with high tensile components to match the higher loads. The result is much more precise and direct roll control with up to 25% more effective bar rate available at lower wheel deflection points. This does NOT mean an outright increase in your bar rate but rather a quickening of its effect allowing more bar rate earlier. Link shape and bush mounts are designed to allow maximum sway bar articulation to ensure full suspension travel while acting more directly under vertical load. Standard length maintains correct sway bar operation.
