Details

Experience Flow-Lock rear diffuser for your Mustang S550 FN, sharing the same durability and technology as our renowned WRX, Golf GTI & MK3 Focus RS line up which is trusted by car enthusiasts worldwide. The rear valance and diffuser fins will clear the Mustang S550 FN dual exhaust tips with ease, and rear bumper removal is not necessary for installation of the diffuser. 10 year warranty applies for the rear valance (excludes ABS fins).

The 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 Mustang S550 FN rear. Front lip splitter is also available for the Mustang S550 FN.

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). It is also possible to install when your car is on the ground.
