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). 

The most innovative rear diffuser on the market, 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 kits assembled and ready for installation - this means zero exposed hardware giving you the cleanest look for your WRX/STI rear.

The rear valance and diffuser fins will clear the WRX VB dual exhaust exit points on the rear bumper. Sharing the same durability and technology as our renowned Silvia S15Golf GTI and Focus RS line up, trusted by car enthusiasts worldwide.

Choose from our textured (scratch-resistant) finish valance or our gloss, low sheen finish to complement your car's style. No more L-brackets, no additional exposed hardware and no double-sided tape, experience the Flow-Lock difference today!
