    SKU: KLC167A Benefit Note: Not many enthusiasts are aware that OEM and more importantly aftermarket sway bar effectiveness can be hindered by worn or inadequate mounts, drop links and lateral stoppers. Whiteline adjustable sway bar links are engineered to be up to the task with top spec, light weight componentry combined with a window of adjustability, eliminating sway bar preload on installation but most importantly ensuring the maximum output of the sway bar for improved grip and better handling.

    SKU: KCA462 Benefit Note:
    Hard acceleration and braking allow the lower control arms to move around significantly causing axle tramp, poor launch and power delivery. Due to the dynamic nature of these lower control arm bushings this also alters the bump steer characteristics effectively generating significant 'toe in' under hard braking. When replacing the rear caster bushing with a low compliance bushing this alters the dynamic effect within the bump steer so Whiteline has cleverly packaged these items together to give you additional camber during turn in which is achieved through the offset in the low compliance bushing, improved anti-lift geometry and neutralised bump steer correction. This kit tightens up the front suspension and makes it more nimble and responsive during acceleration, braking and cornering.

    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.
