    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.

    SKU: KSB550 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.

    SKU: KCA414 Benefit Note: Suffering uneven tyre wear? Sounds like poor alignment. Whiteline camber bolts provide the largest adjustment range (of up to +/- 1.5deg) to get that alignment back in check. Unlike other 'friction' lock designs we use a positive toothed lock washer which means NO SLIP. Simple to adjust and lock time after time with out slipping.

    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.

    SKU: KDT957 Benefit Note:
    The Whiteline shifter bushing kit has been engineered to eliminate that sloppy, plush shifter feel found in the rubber OEM bushings. By drastically reducing the bushing compliance, improves the crispness of cross gate up and downshifts removing the potential of missed and poor shifts. Also incorporating a radius edged flanged bushing head reduces any potential of bushing grab or stiction on the mounting faces during the initial shifting moment allowing a bind free clean gear shift.

    SKU: KSR202 Benefit Note:
    Power steering, aggressive wheel alignment geometry, wider wheels and lower profile tyres have all put radically increased loading on the steering systems of modern cars. Add to that engine bay contaminants such as oil leaks that also help to degrade the performance of steering rack mount bushings. Whiteline steering rack mounts are engineered to outlast and enhance steering precision and feedback.
