    SKU: KCA313-TR Benefit Note:
    A must for lowered vehicles, Whiteline bump steer correction kits are designed to correct bump steer geometry using specially engineered tie rod ends. Reducing the bump steer results in a substantial increase to front roll resistance and a significant reduction in suspension compression of the outside front wheel during cornering. The result is more even weight distribution and improved tyre contact ultimately improving front end grip and cornering speeds.

    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: KBR39 Benefit Note:
    Subaru designed the pitch stop mount to assist in controlling the engine and drivetrain forward and aft twisting motion. The pitch stop is inherently soft due to the plastic body and high compliance rubber bushing design and was built for comfort and not responsiveness or feel. Whiteline's Billet 6061-T6 aluminium pitch stop mounting is built to handle the demands of high torque and power output engines by limiting the amount of movement the engine and drivetrain will place upon the pitch stop. Utilising low compliance bushing technology this eliminates the slop, twisting and shudder found in the OEM rubber bushings allowing for a faster, positive, responsive feel of power delivery on and off the throttle.

    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.

    Suspension bushings are the link between your vehicle and its springs, struts and shock absorbers. Suspension bushings provide the movement and/or mounting points in your vehicle’s suspension system. Hence these suspension components can influence both the ride quality, steering feel, as well as the grip of the tyres, performance of the brakes, and stability of the shock absorbers. Should these suspension components be worn, an unpredictable and more to the point unsafe motor vehicle can be the result.Benefit Note: Whiteline's 'Vehicle Essential Kits' contain all the essential components to 'Activate More Grip'.
