The Karcepts S2000 Rear Sway Bar Kit was designed specifically for square tire setups, but may additionally be used by anyone looking to tame down the on-throttle oversteer characteristics of their S2000.  The large OEM rear S2000 sway bar is fun to drift around, but is not always the quickest way around course.  This sway bar kit achieves near OEM stiffness on it's full stiff setting, yet allows you to soften the rear bar tremendously.  The ability to run a softer rear bar still maintains mid-corner rotation benefits, yet helps put power down better by eliminating too much on-throttle oversteer.  With 13 available stiffness settings, the perfect compromise can be found for every driving style.

  • Billet aluminum arms optimized for strength and weight utilizing the latest FEA software
  • Like a blade style sway bar, roll stiffness can be adjusted quickly, and with one wrench
  • Unlike a blade style sway bar, adjustments are finite, with no possibility of slipping position
  • Rate adjustments are made with the vehicle on the ground, even at low ride heights
  • 13 possible adjustment settings, maximizing tunability and overall range
  • 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
  • 22mm (0.875") diameter high-grade spring steel splined center section for consistent rates
