Stainless steel bracket reinforces the bumper from the inside making the splitter an integral part of the bumper giving it unrivalled rigidity and strength. 

This 3 piece splitter comes pre-assembled from factory.  

Front extensions and winglets are sold separately.

Kit Includes:

  • Side splitters (pair) 
  • 2 Flow Designs stickers
  • Pre-installed threaded brass fittings 
  • Fitting kit

We've developed additional reinforcement studs that bolts the bumper and splitter to the metal OEM cross bar. This achieves better tensile load and downforce whilst reinforcing the bumper. Provisions for transmission and brake cooling have also been taken into consideration.

CNC engraved logo and features, hand polish and packed all in Melbourne's outer east.


  • Front Splitter: 10mm thick polyethylene composite


  • Hand polished satin black
  • Bevelled edges

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. Clear coat will eventually fades & cracks and become undesirable.
