The Karcepts ND Rear Sway Bar Kit was designed specifically for the autocrossing world, but with such a large available range of adjustment, all forms of racing or sport driving may benefit from this product. As it pertains to autocrossing, we wanted to make certain a low enough roll rate was obtainable with our sway bar kit. Too much rear bar, coupled with the ND's low end torque, along with aggressive autocross inputs can easily equate to too much on-throttle oversteer. Multiple design features were implemented to get as close to the ND's factory rear sway bar rate as possible at the full soft setting of this kit. With 5 available hole positions on each arm, and the option to change center section wall thickness, the perfect compromise between forward drive and on-throttle rotation can be found for different setups, surface conditions, and driving styles.

  • Sway bar rate is adjusted with one wrench, in only a few minutes
  • Rate adjustments are made with the vehicle on the ground, even at low ride heights
  • 9 possible adjustment settings, maximizing tunability and overall range
  • Billet aluminum arms optimized for strength and weight utilizing the latest FEA software
  • Light weight, zero deflection solid sway bar mounts provided for precise feel
  • Low friction, lubrication free, dirt resistant, solid polymer bearings require no maintenance
  • Heat treated and plated steel alloy PTFE lined endlinks and all hardware included
  • 0.625" diameter high-grade spring steel splined center section for consistent rates
  • Center section available in 0.095" or 0.188" wall thickness

    Center Section Recommendations: There are many factors with chassis setup that can dictate the ideal center section to be utilized. Being that our sway bar arms offer such a wide range of adjustment, it is difficult to make an incorrect decision on which rear center section to utilize. As a general rule for the ND platform, divide your front spring rate by the rear spring rate. If the front/rear spring rate ratio is less than 2.17, we'd recommend the 0.095" wall center section. Alternatively, if the spring rate ratio is greater than 2.17, we'd suggest choosing the 0.188" wall bar.
