Designed for the most serious competitors, the Karcepts ND Chassis Front Sway Bar Kit leaves no compromises on the table. Hundreds of hours of design time have gone into this kit utilizing CMM technology and FEA analysis. The end result is a 2016+ Mazda MX-5 Miata Front Sway Bar Kit that offers super quick adjustability, an enormous adjustment range, maximum stiffness with minimal weight, and an installation time of just 30 minutes (after the stock bar has been removed).

  • 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
  • 5 adjustment positions per sway bar arm, 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
  • Splined 1.25" diameter x 0.75" gun drilled high-grade spring steel center section for consistent rates, with center turned down to 1.07" to achieve target rates listed below.

Center Section Recommendations: This is Brian's choice for C Street autocross here; more rotation, less understeer, lots of top CS results and several top PAX in our ND2 CS car.

FIAT 124 NOTE: May require modifying or replacing the factory intercooler piping to clear this sway bar.

Brian's Application Notes: I admired and admired this setup but we did not start to carry it until I watched an STR competitor change both his front and rear sway bar settings BETWEEN RUNS at an SCCA event. Took him under a minute to change the rear sway setting, and just over a minute at the front...which is amazing. No other sway setup empowers you to change settings as fast as this setup in my experience, making this setup unique for the hardcore racers who want to dial their setup on the fly. Nonetheless, recommended for the REAL Racers, not the average daily driver because the solid links so good for racing can and will eventually rattle.

WE run the previous generation of this bar in our 2019 ND2 for SCCA CS with our off the shelf KONI SPORT and stock front bumpstops matched to rear VERY HARD Bumpstops. Result has been first place in CS and TOP PAX many times during our first CS season with this car:
