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 on its promises. Made entirely in Germany from high-quality aluminum and powder-coated 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 ones – are made of carbon fiber reinforced plastic. This makes them not only lightweight but also quickly replaceable if necessary. Even if you hit the ground hard in the Karussell corner of the Nordschleife and break a fin, replacement is no problem at all.

The modular design also ensures straightforward shipping and easy transport – even in the 86. No bulky, one-piece monstrosity, but a clever, segmented solution with maximum everyday usability. Assembly is incredibly simple and is demonstrated in the assembly video.

Stability reimagined:
We weren't entirely satisfied with the existing mounting brackets on the market, so we completely redesigned the mounting systems and points. We've incorporated truly robust and stable brackets to secure the diffuser to the vehicle as securely as possible, optimizing efficiency and stability.

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

Installation requires no modifications to the original body mounting points (only minimal work on the side panels is necessary for the Aero or TRD rear). All brackets are robustly designed and attached to sturdy mounting 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 straightforward and eliminates any obstacles to individual approval .

The test report is available to TÜV and can be easily accessed by the respective inspector . The development process involved continuous collaboration with TÜV, therefore the diffuser meets all requirements for individual approval. The corresponding part number on the type plate is permanently attached to the diffuser.

Here you can find the PDF version of the instructions. We estimate the workload for a first-time assembly to be 1 hour for assembly and another hour for mounting on the vehicle.

Performance meets design:
Besides its aggressive appearance, the diffuser also delivers measurable benefits: It reduces turbulence in the axle area and provides more stability and downforce on the rear axle – noticeable on the road and track.

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

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