The most innovative rear diffuser on the market, get the Flow-Lock rear diffuser for your VA WRX or VA WRX STI - sharing the same durability and technology as our renowned Silvia S15, Golf GTI and Focus RS line up, trusted by car enthusiasts worldwide.

The unique Flow-Lock interlocking system allows for the final assembly of the diffuser fins without tools or fasteners. A simple push and click and the kit is assembled and ready for installation - this means zero exposed hardware giving you the cleanest look for your WRX/STI rear.
No more L-brackets, no additional exposed hardware and no double-sided tape, experience the Flow-Lock difference today!
Valance is installed to the car through bolts and nuts while the Flow-Lock diffuser fins simply click into the valance (once locked into the valance it is secure).

Subaru VA WRX/STI Rear Diffuser Material & Finish:
- Valance: 10mm thick polyethylene composite, bevelled edges
- Flow-Lock diffuser fins: 4.5mm thick textured ABS
- Valance: Hand polished satin black
- Flow-Lock diffuser fins: scratch resistant textured ABS plastic
- CNC engraved logo and features
Why do you use polyethylene composite for your products?
Strong, impact-resistant, doesn't corrode or chip, and has excellent abrasion resistance (eg. scraping on driveways!)
What about carbon fibre?
As strong and light as carbon fibre is, it cracks on impact or when under load and/or stress. Clearcoat will eventually fade or crack, becoming undesirable.
Tell me about ABS plastic!
Please note that although all our precision-made ABS accessories are extremely strong and durable, they do not hold the same shatterproof label as our 10mm thick polyethylene composite splitters. The accessories are manufactured in ABS with the intention that they will be lighter, bolt-on attachments that will improve aesthetics and are easily replaceable if they become damaged from varying road conditions.
