Spoiler Extension

Affordable, functional style! We designed this product specially for those of you on a budget, or wanting a more conservative appearance than our street-and-race products.


  • “Gurney Flap” add-on for OEM spoilers: Our simple design works with your OEM spoiler to provide downforce and stability at speed.
  • Mounted with screws for durability: Other spoiler extensions on the market use 3M tape to mount, which is fine if you’re not making downforce. We want you to make more downforce! So, we use 4-6 screws to solidly mount the extension, and 3M tape only for protecting your paint.
  • CNC machined aluminum supports: Svelte but strong, four aircraft-grade 6061 supports keep the extension stiff and gives the signature clean-but-aggressive look that we are known for.

Our spoiler extension is made from polystyrene for long-term durability, and can be painted over or left in its raw finish. Currently supported applications:
