Eibach's PRO-KIT for the non-NISMO Nissan 370Z is a lowering spring set from the brand's long-running PRO-KIT line. The manufacturer positions the PRO-KIT as delivering high performance handling and improved appearance without compromising ride quality. That makes it a practical step up from stock for drivers who want a lower stance and crisper body control without moving to a full coilover setup. Buyers who want more roll control can look at the manufacturer's PRO-PLUS kit (6393.880), which combines the PRO-KIT lowering springs with the ANTI-ROLL-KIT front and rear stabilizer bars.
Searches for this part usually include terms like 370Z lowering springs, non-NISMO Eibach springs, and 370Z Pro-Kit install. Because the springs are a bolt-on swap, the original isolators and dampers are reused, which the manufacturer specifies for Pro-Kit installs. Plan on a wheel alignment afterward, since the manufacturer calls for checking alignment, fender clearance with aftermarket wheels, and brake line routing. Owners on user forums describe the job as manageable for a home mechanic with a jack and hand tools, though it takes most of a weekend day and a second pair of hands helps.
The manufacturer says to inspect and adjust wheel alignment after installation, along with tire and fender clearance when using aftermarket wheels or tires, brake line clearance, and ABS sensor positioning.
Yes. The manufacturer sells the Nissan 370Z PRO-PLUS KIT (6393.880), which pairs the PRO-KIT springs with ANTI-ROLL-KIT front and rear stabilizer bars.
The manufacturer recommends a hoist for this work and says only qualified mechanics experienced with suspension removal should perform it, so treat it as an advanced DIY job. Use jack stands, never work under a car supported only by a jack, and avoid impact wrenches on shock piston rod nuts. Before disassembly, mark the upper strut mount orientation relative to the lower spring perch, since the manufacturer says that orientation must be preserved. Owners on user forums report about five hours for a first install with a jack and hand tools, with the rear easier than the front. Keep the stock isolators and dampers, and install each spring with the Eibach logo facing up.
