STROM E46 Swan Neck Carbon Wing Kit

Overview

Our new Swan Neck Wing kit was designed for our B46 race cars but will work on any E46 coupe and we think Sedan although it has not been verified.

This kit bolts into the trunk hinge mounting points with CNC aluminum mounts and creates an incredibly strong structure for the wing with minimal work. Most people can not believe how securely mounted the wing is both vertically and horizontally. The wing stays extremely stable in operation. The total wing height is also set to be level with the roof so it is legal for most racing classes.

The trunk lid does have to be cut to fit the wing uprights however the cut points are outboard of the trunk seal so the trunk area is still sealed from dirt and water. We provide 3D printed plastic flanges to give the trunk a finished lip. We also provide laser cut brackets and a set of aero latches to mount the trunk. Overall installation of this kit is very easy for its strength.

The wing itself is a custom APR GT-250 pre-preg carbon element with STROM wing endplates. We chose this element for a combination of its efficient shape, low weight, strength and build quality. We provide a gurney flap for cars operating in corner speed ranges of under 120mph with higher angles of attack but it should be removed for cars operating at higher speeds or running low angle of attack.
