2005-2013 C6 Rear Diffuser Fins - Painted

Give your C6 a sharper edge where it counts. These rear diffuser fins from Altec Products add more than just attitude - they help manage airflow under the car, reducing turbulence and contributing to real downforce at speed. The result is a more planted feel and cleaner aerodynamics, especially when you’re pushing the car the way it was meant to be driven. Each fin is molded from high-impact polymer for durability, then finished in correct OE-matched body colors so it looks like it rolled off the line that way. Installation is straightforward with 3M VHB tape, and the included templates and adhesive promoter take the guesswork out while ensuring a secure bond.

  • Fits all 2005-2013 C6 Corvette models
  • Set of 4
  • Painted in correct factory-matched body color for a seamless OEM look
  • Enhances airflow and reduces undercar turbulence
  • Helps generate downforce for improved high-speed stability and performance
  • High-impact polymer construction for long-lasting durability
  • Easy no-tool installation with 3M VHB tape
  • Includes templates and adhesive promoter for precise, secure fit
  • Made in the USA!
