86pARTs | Rear diffuser | GT86 / BRZ I

86pARTs rear diffuser – modular. Robust. Made in Germany.

The 86pARTs diffuser was developed for the track—not a showpiece, but a functional aerodynamic component that delivers what it promises. Manufactured 100% in Germany from high-quality aluminum and powder-coated in black, it stands for uncompromising quality, precision, and durability.

Cleverly thought out down to the last detail:
The fins—with the exception of the two outer fins—are made of carbon fiber-reinforced plastic. This makes them not only lightweight but also quickly replaceable if necessary. Even if you hit a hard landing on the Nordschleife and break a fin, replacing it is no problem at all.

The modular design also ensures uncomplicated shipping and easy transport – even in the 86-inch version. This isn't a bulky one-piece monster, but rather a clever, segmented solution with maximum everyday usability. Assembly is incredibly simple and is demonstrated in the assembly video.

Stability rethought:
We weren't entirely satisfied with the existing mounts on the market, so we completely redesigned the mounting systems and points. These mounts utilize truly solid and stable brackets to optimally secure the diffuser to the vehicle and optimize efficiency and stability.

Compatibility & Variants:
The scope of delivery includes various inserts with which both centrally running exhaust systems (such as Milltek ) and side silencer outlets (such as Don Silencioso-Roar ) can be covered.
Depending on the exhaust, a slight adjustment of these inserts cannot be completely ruled out.

Installation is carried out without any modifications to the original body points (only minimal modification of the side panels is required for the Aero or TRD rear). All brackets are solidly constructed and are attached to stable support points.

Scope of delivery:
Complete mounting kit including brackets, screws, edge protection (heat-resistant under the tailpipes), and all necessary mounting hardware. This makes installation a breeze, and there's nothing standing in the way of individual approval .

The test report is available to the TÜV (German Technical Inspection Agency) and can be easily accessed by the respective inspector . The development was carried out in constant contact with the TÜV, thus the diffuser meets all the requirements for registration via an individual approval. The corresponding part number on the nameplate is permanently attached to the diffuser.

Performance meets design:
In addition to its aggressive appearance, the diffuser also offers measurable benefits: It reduces turbulence in the axle area and provides greater stability and downforce on the rear axle – noticeable on the road and track.

Black powder-coated, with black screws and clean lines – a part that fits, works and is simply GreenFuchs-approved .

The thing weighs a total of 5.5kg, but every gram brings you improved aerodynamics.
