Spoiler Extension – Honda Civic Si Trunk Coupe (Zenki FG4, 2012-2013)

Our rear spoiler extension for the 9th generation FG4 Civic Si Coupe (Zenki) available in ACM and CF. This is designed for the earlier pre-facelift (Zenki) trunk of the Si FG4 Civic coupes, so if you have a Zenki Si Trunk on a non-Si, this will fit. “Gurney Flap” style add-on: Our simple design works with your OEM spoiler to provide downforce and stability at speed. Mounted with screws for durability: The extension solidly threads in to your spoiler at 4 points, with extra tape to protect your paint. No more peeling 3M tape after a few seasons! CNC machined aluminum supports: Four 6061 aluminum supports keep the extension stiff and impart our signature aggressive aesthetic. Laser etched with our logo. Includes all hardware needed to install. ACM - Made from specially-sourced 1/8" Aluminum Composite Material. ACM is a rigid sheet made of two sheets of pre-finished aluminum bonded to a composite core. It has a smooth satin black finish on both sides and comes covered to eliminate risk
