INSTALL DOES NOT REQUIRE REAR BUMPER REMOVAL



Details

Experience Flow-Lock rear diffuser for your Mustang S550 FM, 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 FM 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 FM rear. Front lip splitter is also available for the Mustang S550 FM.

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.

FAQ

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.
