A stock "S" suspension has both a front and rear anti-sway bar but for the sake of overall safety and considering all the drivers in the world, the car will always understeer or push when driven hard into a corner. The most often used correction for this problem is to install a larger rear bar. If this is not an option for some reason, then the answer is to install a smaller front bar. The stock "S" front anti-sway bar is 24mm diameter; this bar is 16mm - enough to make a nice improvement in cornering ability! Installation requires two sway bar bushings, NMS2003B.
