Common Applications

The 326POWER 3D☆STAR Side Under Spoiler is suitable for Lexus RC owners who want to strengthen the lower side profile while retaining the factory body as the foundation of the build. Its flap-shaped design works particularly well on lowered street cars, stance-oriented builds, show vehicles, and complete 3D☆STAR RC projects. It can be installed as an individual side styling upgrade or combined with the matching Front Under Spoiler and Rear Under Spoiler for a coordinated F/S/R setup. Final compatibility depends on the exact Lexus RC model, early-edition specification, factory side-body condition, ride height, and installation method.

326POWER Character

326POWER is known for Japanese tuning culture, lowered vehicles, aggressive fitment, and distinctive aero styling. For the Lexus RC, the 3D☆STAR package combines this character with the premium and sporty appearance of the F SPORT coupe. 326POWER describes the RC aero as using edgy styling throughout, giving the vehicle a dynamic appearance from different viewing angles while keeping the individual aero pieces visually connected.

3D☆STAR Lexus RC F SPORT Design Notes

The complete RC350/300h/200t 3D☆STAR package uses coordinated styling across the front, sides, and rear. The Front Under Spoiler uses an elaborate one-piece shape, while the Side Under Spoiler continues the design through a flap-style lower section. At the rear, the three-piece Rear Under Spoiler combines separate side-under and diffuser sections, and the Roof Spoiler adds another matching detail around the rear window.

Flap-Shaped Side Design

The defining feature of the Side Under Spoiler is its flap-shaped profile. 326POWER specifically states that this shape is incorporated along the sides to create a sense of unity with the front section. Rather than appearing as an unrelated side attachment, the Side Under Spoiler is intended to carry the design language of the front aero along the lower body of the Lexus RC.

Lower-Body Styling

326POWER also describes the side aero as helping tighten the appearance of the underbody. Its position beneath the factory side area gives the car a stronger visual connection between the front and rear aero, particularly when the complete F/S/R combination is installed. The design is primarily presented by the manufacturer as an exterior styling component, so specific aerodynamic performance figures should not be assumed.

Complete 3D☆STAR Exterior Combination

The Side Under Spoiler can be combined with the matching Front Under Spoiler and Rear Under Spoiler as part of the official F/S/R three-piece configuration. The wider RC lineup also includes the Roof Spoiler. The manufacturer’s demo vehicle shows additional components such as wheels, suspension, braking parts, and a modified Manriki Wing installation, but these are separate from the Side Under Spoiler unless specifically stated otherwise.

Installation and Fitment Notes

The Side Under Spoiler should be test fitted to the actual vehicle before painting. Front-to-rear positioning, alignment with the factory side area, ground clearance, left-to-right symmetry, mounting points, and the relationship with any front or rear aero should be checked before final preparation. 326POWER specifically instructs customers to test fit, adjust alignment, and adapt the product to the individual vehicle before painting. If mounting-hole positions are difficult to align, slight adjustment such as elongated-hole processing may be required during test fitting.

Aero Product Notes

The Side Under Spoiler is supplied unpainted in a white gel coat finish, and installation and painting are not included. The component should be inspected, test fitted, aligned, prepared, and painted before permanent installation. Because it extends the lower side profile, final ground clearance should be checked carefully, particularly on lowered Lexus RC builds. The official listing does not clearly identify the underlying material for this specific Side Under Spoiler, so a particular material should not be assumed without manufacturer confirmation.

These additional products should be treated as separate unless specifically stated as included.
