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 9 possible adjustment settings, 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
