Suits MK4 Focus ST
Get the Flow-Lock Rear Diffuser for your Ford MK4 Focus ST, which shares the same durability and technology as our renowned WRX, Golf GTI & Hyundai i30N line up which is trusted by car enthusiasts worldwide. The rear valance and diffuser fins will clear the Focus ST dual exhaust and rear bumper removal is not necessary for installation of the diffuser.
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 MK4 Focus ST rear bumper.
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.

How Strong Are Our Splitters?
HOW IS YOUR SPLITTER SO STRONG?
Each splitter is developed to become an integral part of your stock body kit, giving it unrivalled rigidity and strength so it can absorb scrapes and protect your bumper.
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 can eventually fade or crack, becoming undesirable.
USE OF 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.
