Complete the aggressive look of your MK3 Focus RS with the Flow Designs rear spoiler extension - complete with 4 brackets attaching the extension piece to your spoiler, for increased security and improved visual aesthetic. The rear spoiler extension is designed and developed in-house, at our Bayswater factory in Australia, with our team focused on providing you another sustainable customisation option for your Focus RS!
The unique bracket design are installed with hidden screws, which covert them to an integral part of the rear spoiler once installed. From there you can comfortably lock in your spoiler extension piece with bolts, and all installation hardware is provided. Double-sided is also included for extra installation security. Once the spoiler extension is fully installed, it is the perfect styling match to our Flow-Lock rear diffuser for the MK3 Focus RS, as they both share a fin-like design.
