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.

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 cornering, and weight shifts to one side, the swaybar counteracts it

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.

Upgrade

B210 Sway Bar Upgrade

Bolt a B210 (1974-1978 Sunny) swaybar on. For around $20 and an hour of your time, it bolts in without any mods:

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.

demacoz: MADDAT Sway bar .... $309 delivered to my door. The alternative was to get a custom bar made which could have been $50 less but I would be doing the running around, i would take the risk that it did not fit and it would not come with the fittings .... so, Really it was a no-brainer - thanks Scott

Mad Dat end-links have the topmost end turned 90-degree to match the swaybar hole, similar to these GM units:

B310 bar does not fit B110. It is about 3mm thicker than the 1200 bar. 955mm fixing hole centres.

Custom

Unorthodox setups on local race cars abound.

Installed the second anti roll bar. What a great mod, more or less, gained about 1sec on my rivals, missed 4th place for the day with 0:00.21 of a second.

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.
