Project 004 · ASA-CF, unfinished

Rear bumper cutout

A hand-finished bumper insert that opens up the rear profile and gives the first-generation Copen a sharper, motorsport-inspired stance.

# The build

The rear bumper cutout is the most involved CopenWorks exterior project: a multi-part insert designed to reshape the original bumper and reveal a more purposeful rear profile.

The printed ASA-CF sections need to be assembled, bonded, sanded and painted before installation. Strong, weather-resistant flexible adhesive and careful clamping are essential to keep the piece aligned while it cures.

Installation requires cutting the original bumper. Test-fit repeatedly, mark the cut line while the insert is clamped in position and remove less material than you think you need—you can always trim the opening afterwards.
