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.

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.

Don't waste your money

This looks a lot better in pictures than in person. The fins look very cheap with a weird textured finish that does not look good, you could probably make something better with a 3d printer. The worst part is they don't even fit right, from a side view the fins have a half centimetre gap which is painful to look at and from a back view one of the fins has a curve in it which is very obvious since the fins line up with the factory fins on the oem valance. I wish i could upload pictures that will show all these flaws but there is no option for this. Worst part is i can't take them off because i had to drill a lot of holes in my brand new mustang which can't be undone. As soon as i can get my hands on a new factory oem valance I'll be taking these off. Please don't make the same mistake as me, it will end up costing you a lot of money, if you insist then please take mine for free, they will be on gumtree within a few weeks.
