Stillen technician Sam Camarillo provided us with some insight into the quirks, shortcomings and time-oriented problems suffered by Z32s. Up front, Sam was quick to point out the tension rod. Sam informed us that the unit's bushing is filled with silicone and, over time, they can crack and develop leaks. The car loses some of its handling feedback and, in some cases, the wheel and suspension sub-assembly will actually move under hard braking. Stillen has addressed this shortcoming with its adjustable tension rod. The Stillen piece deletes the stock bushing altogether, replacing it with a rod end-type bushing. It is adjustable to allow for alignment, because many Zs have had impacts with parking barriers and this is the only way, short of a frame alignment shop, to fine tune the alignment.

At the stern, it is the rear A-arm that is a problem child of sorts. In some cases, the stock arms do not allow enough camber adjustment to align the car to spec. Camarillo said that, for some reason, the driver's side is a big problem; 75 percent of the cars he sees are not able to attain proper adjustment on this side. Sam is a perfectionist, and when he adjusts the suspensions of customers' cars, he wants total precision, but he reports he has problems meeting the manufacturer's range of adjustment, much less the exact number. To correct this situation, Stillen manufactures its own adjustable rear A-arm. The unit is stoutly built and provides an additional 1 to 1.5 degrees of adjustment.

The meat of this article will showcase how a typical Z owner could upgrade the handling performance of his Z32 and further reveal some of the Zs problem areas. The accompanying photos will illustrate the installation of shocks, springs, sway bars, camber kits, tension rods A-arms and strut tower braces.
