Will this interfere with my front splitter or air dam?

The D-Spec lip is designed to sit cleanly beneath the non-sport bumper line. Verify your existing splitter or air dam clearance by checking the mounting locations on your vehicle before installation. If you're running a factory lip, this replaces it rather than stacking on top.

Should I seal the carbon fiber edges after installation?

Yes. Sand the mounting surfaces lightly, apply a thin bead of silicone or adhesive sealant at the connection points, then bolt down. This prevents water entry into the weave during wash and rain. After installation, a UV-protective clear coat applied to the exposed edges will extend the finish life.

How much does this weigh compared to the OEM bumper lip?

Real carbon fiber is significantly lighter than the factory plastic alternative. The exact weight savings depend on your existing bumper setup, but the material itself delivers noticeable reduction in unsprung weight at the front end.
