  4. Front Control Arm Lower - Inner Rear Bushing Kit-Double Offset
    SKU: KCA428 Benefit Note:
    Whiteline Anti Lift Kits 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.

  5. Front Engine Torque Arm - Assembly
    SKU: KDT974 Benefit Note:
    The torque arm assists in controlling the engine and drivetrain forward and aft twisting motion. The torque arm is inherently soft due to the high compliance rubber bushing design and was built for comfort and not responsiveness or feel. Whiteline's torque arm mount bushing 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.

  6. Front Engine Torque Arm - Bushing Kit
    SKU: KDT915 Benefit Note:
