Through new manufacturing techniques and tons of real-world testing, Karcepts has simplified the center section offerings for the S2000 chassis. Previously we had offered uniformly tubular center sections with differing wall thicknesses. These were industry standard material offerings that gave us the rates they gave, but were not completely ideal. We are now manufacturing center sections starting as a 1.25” O.D. x 0.75” gun drilled (0.250” wall thickness) bar, and then turning down the middle portion to achieve more targeted sway bar rates. Our prior 0.120" wall bar was a bit too soft of a range for most, and the 0.188" was only 1 hole adjustment off on each arm in comparison to the most popular 0.250" wall bar. These prior 0.120" and 0.188" wall bars have now been replaced by a hybrid 1.14" turned down bar (it still has 1.25" O.D. ends, but the middle of the bar is smaller O.D. to get a better range of rates).

Note: Brake line mounting brackets, remote reservoir lines, nitrogen fill connections, and any other potential obstructions mounted inboard of the shock body may prohibit the quick adjustment feature of this sway bar kit. OE shocks, Koni Sport shocks, and any other shocks with OE style brake line mounting brackets can still retain quick adjustment functionality when swapping the left shock to the right side, and vice versa (effectively eliminating the interference without having to grind off the brake line brackets completely). Please consult us before purchasing if you have any concerns with achieving quick adjustment for your application.

Confirmed quick adjustment with the following dampers: MCS 1WNR, MCS 2WNR, MCS 2W (w/ reservoir lines facing forward), MCS 3W (w/ reservoir lines facing forward), MCS 4W (w/ reservoir lines facing forward), Moton Clubsport (w/ reservoir lines facing forward), Koni 3011 (w/ nitrogen fill connections facing outward), JRZ RS One, JRZ RS Two, JRZ RS Pro (w/ reservoir lines facing outward), Ohlins R&T/DFV (sway bar arm installation position may require adjustment), KW V3 & KW Clubsport (brake line brackets will need to be bent and sway bar arm installation position may require adjustment), Penske 8300, Koni Sport (w/ left and right shocks swapped), OE (w/ left and right shocks swapped)

Karcepts S2000 Rear Sway Bar Kit, .0875” O.D. x 0.095" Wall

This is the .095in bar version. Really fine tune your S2000 balance with a rear sway bar. Depending on a number of things (tires, power level, type of driving/competition), we'll use the rear bar to change the car's balance. Generally, if you have a hard time getting the power to stick, loosen the rear bar until you can get the power down without drama.

Honda S2000 Front Lower Ball joints, Roll Center + Offset

This is our preferred front lower ball joint. Helps correct Roll center along with additional front camber. We've ran "the other" extended ball joints and have found too them to add too much leverage on the lower spindle mounts. This leads to the spindle failing and gets very sketchy. We have yet to see a spindle failure since switching to these.
