  16. 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.

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

Suits both Automatic or manual transmissions.
