Suits Pre-facelift Sportback only

Improve the aero aesthetic of your Audi S3 8V PFL Sportback with Flow Designs splitter set! The kit includes front and side splitters, Flow-Lock rear diffuser, rear spats and adjustable accessories all round. Our splitters are designed to fit perfectly to your stock bodykit and are proven as the most durable on the market.


Concealed steel brackets are the key feature of this kit.
The goal was to create a bracket that is discreet and strong without the use of any exposed hardware whilst maintaining the correct angle.

Borrowing the technology of Flow-Lock, our black powder-coated brackets can be slipped in-between each diffuser fin and locked into place. With a simple “push and click” action, the diffuser is assembled and ready for installation.
No “L-Brackets” no double-sided tape, no exposed hardware.
All this effort to ensure you have a strong and reliable product that is easy to install also pleasing the eye.

Kit Includes:

  • Rear valance
  • 4 black powder-coated steel mounting brackets
  • 4 pairs rear Flow-Lock diffuser fins
  • 2 Flow Designs Stickers
  • Fitting kit


  • 10mm thick polyethylene composite rear valance with beveled edges
  • 4.5mm thick Scratch resistant textured ABS Flow-Lock Diffuser Fins

    Why do we use Polyethylene Composite for Flow Designs Splitters?

    Strong, impact-resistant, doesn't corrode or chip, and has excellent abrasion resistance (say… from scraping on driveways and road all the time?)

    Carbon Fibre is better isn’t it?

    As strong and light as Carbon fibre is, it CRACKS on impact or when under load and/or stress. Clearcoat will eventually fade & cracks and become undesirable.
