Common Applications
The 326POWER 3D☆STAR RZ34 Rear Under Spoiler Type 1 is suitable for Fairlady Z owners who want to give the lower rear section more visual presence without dramatically changing the original character of the vehicle. Its restrained design works particularly well on lowered street cars, stance builds, show vehicles, and RZ34 projects using the matching 3D☆STAR Front and Side Under Spoilers. Final fitment depends on vehicle condition, bumper alignment, ride height, surrounding aero components, and installation method.

326POWER 3D☆STAR RZ34 Character 
The 3D☆STAR RZ34 aero package was developed around the proportions and distinctive silhouette of the new-generation Fairlady Z. Rather than overwhelming the original body lines, 326POWER uses carefully positioned lower aero elements to create a visually lower and more complete appearance while maintaining the recognizable styling of the RZ34.

RZ34 Rear Under Spoiler Design Notes
326POWER explains that the rear under spoiler was designed to preserve the strong qualities of the factory rear styling while adding moderate volume only to the areas where it was considered necessary. This approach gives the rear of the car additional visual depth without making the design unnecessarily heavy or complicated.

Balanced Rear Styling
The Rear Under Spoiler Type 1 focuses on enhancing the lower rear profile rather than replacing the complete rear bumper. Its restrained shape works with the original bumper design and helps visually lower the rear of the RZ34 while retaining the vehicle's original character.

Matching 3D☆STAR Type 1 Components
326POWER also offers matching Front Under Spoiler Type 1 and Side Under Spoiler Type 1 components for the RZ34. The Front, Side, and Rear Type 1 pieces are also available as a three-piece set, allowing owners to create a coordinated lower aero treatment around the complete vehicle.

Installation and Fitment Notes
The Rear Under Spoiler must be test fitted to the actual vehicle before painting. Rear bumper alignment, left-to-right positioning, mounting locations, body gaps, ground clearance, and overall fitment should all be checked before final preparation. 326POWER specifically requires test fitting, alignment adjustment, and vehicle-specific fitment correction before painting. If mounting-hole positions are difficult to align, slight adjustment such as elongated-hole processing may be required during test fitting.
