Functional Aero Chassis Mounted Rear Wing Kit is an all-in-one solution to providing your E92 with more downforce necessary to improve rear tire grip for improved handling. This kit was engineered for all E92 models and includes all of the components necessary for a comprehensive install and feature top-tier quality components for long term durability, such as the carbon fiber wing, billet aluminum mounting brackets, and powdercoated aluminum uprights with x brace.

The spoiler has an adjustable AoA (Angle of Attack) between approximately 0°- 20° to perfect downforce to drag ratio. The end plates are adjustable for aerodynamic needs, and the 5mm thick powdercoated aluminum uprights maintain wing position at track speeds.

PART DESIGN

All components designed and engineered to provide functional aerodynamic benefits, specific to the E92 body, using FARO ARM laser scanning technology and SolidWorks 3D CAD modeling for precision fitment along with FEA (Finite Element Analysis) to provide the best balance between downforce while minimizing drag.

Carbon Fiber Rear Wing:

Optional 60", 65", 70" widths

Made from lightweight, hand-laid carbon fiber material with pre-impregnated 2x2 twill weave carbon fiber cloth and epoxy resin, then autoclave cured and finished in a durable gloss clear coat for UV and heat protection

Lightweight aluminum uprights and x-brace

Upright brackets sandwich between the bumper crash beam and the chassis

Powder coated steel brackets to attach uprights to chassis

3D wing profile with forward and upward curvature

Anodized aluminum threaded inserts at the wing ends and mounting bosses

Wing End Plates:

Aerodynamic profile, made from 12ga 5052 aluminum, then black anodized

Adjustable end plate angle

Includes stainless steel mounting hardware

Wing Mounting Brackets:

Made from 6061-T6 billet aluminum, then black anodized

Adjustable pitch to dial in the spoiler's angle of attack between approximately 0° and 20° ; each hole adjusts ~1.33° of AoA

Includes M8 stainless steel, black oxide hardware

Subtle, post-anodized engraved logo

Upright Brackets:

Made from 5mm thick 5052 aluminum, then powdercoated wrinkle black

Reinforced with a matching x brace

Utilizes zinc-coated rivet nuts within the upper body shell (requires drilling into the shell and trimming of the factory hatch spoiler) and billet aluminum lower mounting brackets (requires drilling through the hatch shell)

Chassis Mounting Brackets:

Sandwiched between the bumper crash beam and the chassis

Powdercoated wrinkle black for strength and durability

INSTALLATION AND SUPPORT

Will require drilling / cutting into the body for permanent installation. Professional installation is highly advised.
PERFORMANCE FEATURES

Performance data metrics are collected utilizing FEA (Finite Element Analysis) software to validate our design

Assists with rear tire contact by applying downforce over the rear axle. This is very beneficial on RWD vehicles where rear traction loss may occur at high speed cornering.
