Nissan 300ZX Suspension Upgrade - Suspension Resuscitation

In 1990, the Z32 came out of the gate running and throughout its production run the 300ZX was Nissan's high-tech flagship in the States. Sales escalated for the first three years, then the rising popularity of the SUV and the increasing price tag of the Z began to erode its sales performance. It exited stage left in 1996, about the time the RX-7 bowed and two years before the demise of the Supra. Despite its lackluster dealership performance, the Z32 has been a strong performer in the aftermarket from Day One and remains a force as we move into the new millennium. The sporty coupe has a rich racing history and the technological muscle to produce prodigious power with moderate effort.

No matter how well you care for your car, you can't cheat time. The 1990 edition is a decade old and with a majority of overall production coming early in the production run, there are a great number of seven- to 10-year-old Z32s prowling the streets. As parts and/or component systems wear, they need replacing, which is where the "upgrade or replace" dilemma surfaces. Nowhere is this tug of war more evident than in the suspension system. Handling prowess is one of the 300ZX's major strengths, and time can steal away the g-forces. Since this loss happens gradually over the years, many enthusiasts will not know what they are missing.

Do you go to the dealer and replace the aging suspension parts with OE offerings or step up and bolt on aftermarket hardware, enhancing performance instead of merely reclaiming it? Cost is a concern, for sure. But in some cases, the OE parts hit the wallet harder than the custom parts. Our search for the possibilities led us to Stillen, a leading-edge tuner of the Z-and most everything Nissan.
