Toyota GR86 TRD V7 Side Skirt Extensions Review: Style, Fitment & Performance

The Toyota GR86 is already a stunning sports car straight from the factory, but for many enthusiasts, the desire to push its visual and aerodynamic potential is irresistible. One of the most popular upgrades in the GR86 community is the addition of side skirt extensions, which not only enhance the car’s aggressive stance but also improve airflow along the sides. In this review, we take a close look at the TRD V7-style side skirt extensions designed for the 2022+ Toyota GR86, evaluating their design, build quality, fitment, and real-world performance.

Whether you’re building a track-focused machine or simply want to give your daily driver a more planted look, side skirt extensions are a smart upgrade. They bridge the gap between a front lip and rear diffuser, creating a cohesive aero package. We’ll also compare them to other aero components like canards and splitters, and show you how to pair them with existing parts from your build.

Design and Aesthetics

The TRD V7 side skirt extensions are inspired by Toyota’s own TRD (Toyota Racing Development) design language, which emphasizes sharp lines and functional aggression. These extensions attach to the factory side skirts, adding a pronounced lower lip that visually lowers the car and widens its stance. The design features a subtle fin or blade-like profile that channels air along the rocker panel, reducing turbulence and improving high-speed stability.

Made from durable polyurethane (PU), these extensions offer a perfect balance of flexibility and rigidity. Unlike rigid carbon fiber or ABS plastic, PU can withstand minor impacts without cracking—ideal for daily driving on uneven roads. The matte black finish complements most GR86 paint colors, though many owners choose to paint-match for a seamless factory look. The overall aesthetic is sporty without being over-the-top, making it suitable for both street and track use.

• Aggressive TRD-inspired styling that enhances the GR86’s side profile
• Durable polyurethane construction resists cracking and fading
• Matte black finish or paintable for a custom look

Fitment and Installation

One of the biggest concerns with aftermarket side skirt extensions is fitment. The TRD V7 extensions are designed specifically for the 2022+ Toyota GR86 (and its twin, the Subaru BRZ), ensuring a direct bolt-on installation. They use existing mounting points along the rocker panel, plus 3M automotive-grade tape for added security. No drilling or permanent modification is required, which is a huge plus for those who want to revert to stock later.

Installation typically takes about an hour with basic hand tools. The kit includes clear instructions, mounting hardware, and adhesion promoter for the tape. It’s important to clean the mounting surface thoroughly and apply the tape at room temperature for best results. Once installed, the extensions sit flush against the body, with no noticeable gaps. For reference, many owners pair these with a front splitter like the 2022-2026 Subaru WRX V7 Splitter for a complete aero package, though the WRX splitter requires some adaptation for the GR86.

• Direct bolt-on fitment for 2022+ Toyota GR86 / Subaru BRZ
• Includes 3M tape and hardware – no drilling required
• Installation time: ~1 hour with basic tools

Performance and Aerodynamics

While side skirt extensions are primarily cosmetic, they do offer real aerodynamic benefits. By reducing the amount of air that flows under the car, they help lower lift and improve high-speed stability. This is especially noticeable when combined with a front lip and rear diffuser. The TRD V7 design incorporates a small aero fin that helps direct air away from the rear wheels, reducing drag and improving cooling for the brakes.

On the road, the difference is subtle but appreciable. At highway speeds, the car feels more planted, and crosswinds have less effect on steering. On a track, the reduced underbody airflow can translate to slightly faster cornering speeds. However, the biggest benefit for most owners is the visual transformation—the car looks lower, wider, and more purposeful. For those seeking a more dramatic aero setup, pairing these extensions with a rear diffuser such as the 2022-2026 Subaru WRX V3 Diffuser (with minor modifications) can create a cohesive track-ready look.

• Reduces underbody airflow for improved high-speed stability
• Subtle but noticeable improvement in crosswind handling
• Best results when paired with a front splitter and rear diffuser

Comparison with Other Aero Upgrades

Side skirt extensions are just one piece of the aero puzzle. For a complete transformation, many GR86 owners also add canards, front splitters, and rear spats. Canards, such as the 2015-2017 Ford Mustang V1 Canards, are designed for different vehicles but illustrate the concept—they redirect airflow at the front bumper to increase downforce. For the GR86, dedicated canards are available from various brands and can be paired with side skirt extensions for a race-inspired look.

Another popular upgrade is the rear spat extension, which adds visual width to the rear bumper and helps manage airflow exiting the wheel wells. While not a direct substitute for side skirt extensions, rear spats complement them by creating a continuous aero line from front to rear. The 2015-2022 Dodge Charger V1 Rear Spat Extension is a good example of the design philosophy, though it’s not GR86-specific. For GR86 owners, dedicated rear spats are available that match the TRD V7 side skirt extensions perfectly.

• Side skirt extensions work best as part of a complete aero kit
• Canards add front-end downforce; rear spats balance the rear
• Matching all aero components creates a cohesive, professional look

Durability and Maintenance

Polyurethane is known for its durability, and the TRD V7 side skirt extensions live up to that reputation. They resist UV damage, remain flexible in cold weather, and can handle minor scrapes without cracking. However, like any aero part, they are exposed to road debris, salt, and stone chips. Regular cleaning with mild soap and water is recommended, and applying a UV protectant spray can help maintain the matte finish.

If you do damage an extension, replacement is straightforward since they are individual pieces. The 3M tape can be replaced, and the hardware is standard. For owners who frequently drive on rough roads, the flexibility of PU is a major advantage over carbon fiber or ABS plastic, which can shatter on impact. Overall, with basic care, these extensions should last the life of the car.

• Polyurethane resists UV, cold, and minor impacts
• Clean with mild soap and water; apply UV protectant
• Individual replacement possible if damaged

The Toyota GR86 TRD V7 side skirt extensions are an excellent upgrade for anyone looking to enhance their car’s appearance and aerodynamics. They offer a perfect blend of style, durability, and easy installation, making them a top choice for both daily drivers and track builds. If you’re ready to take your GR86 to the next level, explore the 2022+ Subaru BRZ & Toyota GR86 Base AFD Duckbill for a matching rear spoiler that completes the look.
