When changing bars, raise the car so you can get under it easely BUT more importantly put blocks under the tyres so they are not hanging down. The positive camber of drooping wheels prevent you from getting the bar in. Make sure both sides are jacked evenly.

Current revision

The Anti-sway bar, also known as a swaybar, helps bumps on left side of the road from affecting right side of car and vice-versa. Nissan calls this the stabilizer. The swaybar rotates in bushings bolted to the chassis, and is fastened at each end to the LCAs.

Contents

Overview

The stabilizer is a spring from one side of the front suspension to the other. When one wheel goes over a bump, the end of the bar rises, resisting it (assisting the coil spring). But the bar is resisted by the other side of the car, thus overmuch Body Lean is prevented.

  • When travelling a straight, smooth road, the swaybar has zero effect
  • When one wheel goes over a bump, the swaybar acts as spring
  • When both wheel go evenly over a speed bump, the swaybar has no effect
  • When cornering, and weight shifts to one side, the swaybar counteracts the shift

So changing to a stiffer bar mainly affects cornering -- it corners flatter with less bad camber change. Therefore corners faster with less tire squeal. The stock coil springs are quite light, so a much stiffer bar works well and doesn't overpower a 1200.

When changing bars, raise the car so you can get under it easely BUT more importantly put blocks under the tyres so they are not hanging down. The positive camber of drooping wheels prevent you from getting the bar in. Make sure both sides are jacked evenly.

what a difference it makes I can't believe the difference I can finally go around corners at a decent speed. For anyone who's looking for a quick and cheap handling improvement this is the way to go.

Rear Bar Notes

Sway bars really should only be used as a fine-tuning device.

If you put on a rear bar you will end up lifting an inside rear wheel under hard cornering (unless you've got an LSD). Quite frankly you would be better to maybe throw another top leaf into the springs along with some heavier front coils.
SCCA Racer Tom: To stiff a rear bar will have the inside rear wheel unloading and cuase excessive wheel spin on corner exits , even with the stock A12. Next and more importantly sway bars are meant to be installed as a set , if you slap a rear bar on with the stock front your car will oversteer wildly. This may work fine at an Autocross but anything over 50 MPH the car will be a handful.Also keep in mind that big sway bars will affect the suspension compliance. My 1200 racer uses a 7/8 front and a 5/8 rear both are from Addco.
