Rear Spoiler Extension [Mk4 Focus]

mountune's signature rear spoiler extension upgrade is now available for owners of the Mk4 Focus (hatchback) to add an aggressive aesthetic boost and enhance road presence.

Carrying over the existing DNA of the upper and lower strafe feature for a more aggressive look, our design team hand-modelled the initial set to achieve the perfect aesthetic balance, before being cloud-scanned and brought into the digital world of CAD.

This allowed our engineering team to then ensure perfect symmetry between both sides and most importantly, to make sure the end product followed the surface detail of the OE rear spoiler perfectly.

Manufactured from injection moulded ABS and finished in a Satin black to match other OE vehicle trim detail, the rear spoiler extension also features a recess which houses a genuine mountune flag badge and is supplied with the required adhesive, allowing easy DIY installation in a matter of minutes when following the simple steps below:

  • Clean the surface 
  • Apply a thin line of adhesive in the recess of the extension
  • Slide it into place
  • Secure with strips of masking tape until the adhesive has dried

No measuring, aligning or 'making good' required, just fit and enjoy the visual boost the mountune rear spoiler extensions instantly add.

Note: Currently, not compatible with later rear spoilers that are supplied with a black, additional cover on the lower side of the spoiler. Please check prior to ordering.

The Perfect Balance

We've accentuated the existing OE lines, whilst adding an aggressive boost to the rear end aesthetics that looks just right from every angle, all combined together with an OE-like quality fitment and finish.

    These are very good quality and easy to fit, packaging was excellent. Usual quad from Mountune, can’t wait for the new things they develop for the ST mk 4.
