Key Features
Race proven: Not just a competitor but a winner. We have set multiple motorsport lap records with our wing element.
2D/3D hybrid profile: Developed in CAD, optimized in CFD. Our super-efficient wing profile can produce 500+ lbs of downforce at 160mph with minimal drag. See CFD data in pictures.
Light & stiff construction: 100% carbon fiber pre-preg layup around a composite accordion core — 6.5 lbs without sacrificing strength.
Finely adjustable: Black powder coated aircraft-grade 6061 aluminum wing risers with adjustment holes in 1-degree increments (16 degrees total).
Notes
- Holes will need to be drilled into the trunk to mount.
- Carbon fiber motorsport wings come in a matte finish from manufacturing. Apply clear coat for extended outdoor use.
- Carbon endplates are included as standard.
Fitment & Sizing
Wing Stand Height: Measure how far you want the top of the wing to rise, subtract 1.5 inches, and round to the nearest available option. We typically recommend aligning the top of the wing to the roof height of the car.
