Mandatory Pre-Installation Protocol

1. Dry Test-Fit First

All components must be dry-fitted to the vehicle prior to removing tape liners, applying adhesion promoters, cutting, sanding, or drilling. Components altered or permanently mounted are deemed accepted in full and void return eligibility.

2. Visual Documentation

If an uninstalled clearance issue is found, email 2–3 clear photos showing the unmounted test-fit alignment to support@carbonwerk.co within the 30-day inspection window for prompt resolution.

Composite Construction: Checked for structural core integrity, edge trimming consistency, and weave symmetry prior to packaging.
Post-Delivery Exclusions: Normal wear and tear, road debris strikes, rock chips, scraping/bottoming out, improper installation, altered hardware torque, chemical exposure, or environmental weathering after delivery.
