Professional installation is required.
From my experience with it, the bumper requires little to no fitment work.
It does require a complete paint & finishing process, along with installation.
Dual snorkels
After many requests, a variant of the mold was created to offer a dual snorkel variant of the bumper. The CSL windshield fluid reservoir will no longer fit on the passenger side.
Poorly fitting replica fiberglass bumpers are available from the usual suspects. My threshold was OEM fitment and nothing less.
At over 5,000$ USD excluding shipping, the Genuine BMW CSL carbon bumper was nothing more than a pipe dream.
In this Special Series, I documented my experiences with 2x CSL carbon fiber bumpers, including their boxing impressions, subtle differences, fitment and final impressions.
