Z1 Motorsports Adjustable Front Upper Control Arms for '90+ Nissan 300ZX models.
Due to the fact that the majority of 300ZXs today are either driven exclusively on the street or are dual purpose vehicles, seeing occasional track usage, most customers prefer to have an aggressive and crisp handling suspension without the increased harshness and ride discomfort. With this in mind, Z1 has created the STREET Version of the Z1 Motorsports Front Upper Control Arms. Pairing up with Energy Suspension, an industry leader in aftermarket polyurethane bushings for the automotive industry, a custom bushing set was created to balance overall driving performance while ensuring ride quality. An added indirect feature of the STREET Version's use of bushings is that there is no need for solid tension rods to "protect" the bearings like in the majority of the current arms on the market. The Z1 Z32 FUCAs are serviceable and rebuildable. We offer the urethane bushings and new steel inserts separately HERE. Weighing in at 3.85 lbs each, the STREET Version matches with weight of the OEM Upper Control Arms and mimics a similar ride quality/comfort.
ULTRA-Light RACE VERSION:
Z1 Motorsports ULTRA-Light RACE Front Upper Control Arms are designed for the serious driving enthusiast or a "track use only" 300ZX. Using NSK double sealed ball bearings, the ULTRA-Light RACE Version provides the most direct and uncompromising driver feel. Weighing in at 3.25 lbs per arm, the ULTRA-Light RACE Version is over half a pound lighter than the stock arms and is MUCH lighter than its competitors.

Now available with an extended adjuster that gives you more than an inch of additional positive camber adjustment for those extremely lowered cars. Please note when using the extended adjuster you also lose more than an inch of negative camber adjustment. Be sure to choose the correct option for your vehicle.
Please Note:The use of thread locker is recommended under the jam nuts once final alignment adjustments have been made. Z1 Motorsports HIGHLY recommends the addition of either Solid Tension Rod Bushings or Solid Adjustable Tension Rods with solid, spherical heim joints when installing the ULTRA-Light Race Version Front Upper Control Arms. Failure to add these components will result in premature bearing failure. Z1 considers solid pivot points to be considered for Race Use, and require routine race standard maintenance and inspection.
Buyers of the ULTRA-Light Race Version should be aware that additional stiffness, vibration and noise will result by installing the solid style tension rod bushings. Customers not comfortable with or are concerned about the increase in harshness or noise should purchase the STREET Version.
