Nissan S14 rear suspension kit is designed with racing in mind all components are from high strenght steel, including sheetmetal components, tubes, tube ends and rod end housings. Good materials with design optimization has lead into major weight reduction. The knuckle weighs ~2,7kg and at the same time can hold 5-6G of loadpeak at tire contact patch on 1100kg car. S14 Wisefab knuckle has revised kinematics with built in anti-squat higher roll center, less camber gain and adjustable bump steer for maximum grip and performance. Every part on the Wisefab S14 suspension kit is available by spare parts.


  • Revised kinematics, not just dropped knuckle.
    If maximum grip is the keyword and combination of good roll centre position, camber gain, antisquat and bumpsteer are required, then dropped knuckle is not good enough. That is the reason why we totally revised the kinematics.
  • Light weight and strong.
    More than 10kg of weight reduction over original components and still maintaining required strenght and stiffness.
  • CrMo³ rod ends and sphericals.
  • Bump steer adjustment.
    Possibility to adjust bump steer by changing rod end location in a slot.
