Does this bumper have cutouts for fog lights or sensors?

Verify your CLK's original bumper opening locations before final fitment. The C63 profile may differ slightly from your base model — measure the existing cutout positions and compare them to this panel's layout to confirm alignment with your fog light or sensor hardware.

Will this FRP bumper require reinforcement or bracing?

FRP bumpers are designed to support standard mounting hardware. Check that your existing mounting bracket configuration aligns with this panel's reinforcement points before final installation — factory mounting hardware is not included.

What's the best way to prep and paint this bumper?

Sand and prep the surface with standard automotive procedure, then apply your chosen color coat and clear. FRP accepts automotive paint systems well — verify compatibility with your finishing products before committing to the full application.
