Will these diffusers interfere with the trunk seal or rear bumper fitment?

The two-piece design mounts to existing bumper attachment points without modification. Before installation, verify that the diffuser edges sit flush with your bumper body line — no gaps or overlap. If your vehicle has been in a prior accident or has non-OEM bumper work, test-fit first to confirm clearance.

Should I use adhesive or fasteners to install these?

These diffusers are designed for bolt-through installation using your vehicle's factory rear bumper mounting holes. No drilling required. Adhesive alone is not recommended for diffusers that experience road airflow and vibration. Use appropriate stainless steel fasteners and apply threadlocker for long-term security.

How do I maintain the finish and prevent cracking?

Real carbon fiber requires gentle care. Wash with pH-neutral soap and soft microfiber cloths — avoid pressure washers and harsh chemicals. The clear coat layer protects the weave from UV damage; inspect it annually and reapply clear coat if you notice dullness or micro-cracks. Park in shade when possible during extended storage.
