300zx Z32 Stillen 304700 Adjustable Sway Bars & Powertrix Front/Rear Sway End Link Combo

STILLEN SWAY BARS

An absolute must for handling. The hollow stock bars are replaced with our stronger, solid bar. The front bar is 28mm diameter and 2 position adjustable. The rear bar is 21mm diameter and 3 position adjustable. Adjustability allows the discriminating driver to fine tune settings that match conditions and preferences. All STILLEN Sway Bars come complete with quality hardware, silicon impregnated polyurethane bushings and installation instructions.

POWERTRIX REAR SWAY BAR LINKS

1. Bracket made from 0.105'' thick steel (almost twice the thickness shown in the picture) and clear cadmium coated for corrosion resistance.

2. 3 piece precision links (higher quality than standard 2 piece links) with hard chrome plated steels balls, heat treated steel alloy races, and teflon impregnated race liners that never require lubrication.

3. Grade 8 through hex bolts and alloy steel button head bolts with nylon-insert hex locknuts

"Many of the popular aftermarket bars have end links that are not even at the ends, causing the bar to pre-load the car in one direction or the other. To prevent jacking weight on the car, which can interfere with corner weighting and other set-up operations, you must shim the end links to assure that the bar is not twisted and pre-loading any of the wheels.

Also, the end links are often kinked at acute angles on lowered cars. This is because most aftermarket bars are designed on cars at stock height. The stock rubber or urethane bushings can also contribute to play in the bar, binding of the bar and limiting its effectiveness by taking up body motion in mushing the soft material.

The rear end links on Project Z displayed some of these negative attributes. Our bar was bent slightly off so we had to shim the end links on one side during our original installation. Since the car was lowered, the end links were bent at an acute angle, and the end link bushings took up some of the bar's effectiveness, especially when the rear bar was set, like ours, to full stiff.

To cure this, we installed some NuTech adjustable Speed-Link end links. The NuTech end links replace all of the stock rubber or aftermarket polyurethane with zero play, inflexible spherical bearing Heim joints. Now every bit of body roll gets transferred into the sway bar, greatly increasing its effectiveness. The NuTech end links are also shorter and adjustable so they can be set as close to 90 degrees to the bar as possible. This ensures that all of the body motion gets transferred into the bar right away, rather than being wasted on straightening out the end link. The smooth-acting Heim joints also eliminate any bind that is present in the bushings. Finally, the individual length of the links can be adjusted to eliminate wheel preloading caused by a slightly mis-bent anti-roll bar. This also helps keep the end link angle close to 90 degrees because the overall length of the link can be adjusted when the link is moved to different stiffness settings.

Although the NuTech end links seem like a small detail, we could actually feel the difference. The new links helped the car rotate better in lift-throttle conditions. In fact, the bar works so much better, we may have to re-adjust it one-step softer as the car is a bit too tail-happy now.
