The new Flow Designs splitter set for Subaru WRX/STI (VA) include front & side splitters, rear spats & rear under spoiler extension. Every piece of this set has optional adjustable winglets to make exterior styling truly a custom artform. Everything is hand polished to satin black & easy to install!


Installation is simple, and to make things even easier, we have pre-drilled all our parts so there is no guesswork for you.
We also implemented visual prompts in our design so you know exactly where the splitter is meant to sit in relevance to the OEM side skirt.

The pre-installed brass thread is hidden from sight and will accept our adjustable rear wingletswhich are sold separately as a bolt-on accessory to suit our rear spats.

By purchasing this splitter, the pre-pressed in threaded brass inserts will now acceptVA WRX/STI adjustable side winglets (sold separately)

Kit Includes:

  • Rear spats (pair)
  • Pre-fitted brass threads for winglets (sold separately)
  • 2 Flow Designs stickers
  • Fitting kit

Winglets sold separately

  • Subaru VA WRX/STI rear winglets (pair)


  • 10mm thick polyethylene composite, bevelled edges


  • Hand polished satin black

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, isnt 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.
