Will this interfere with my factory front fascia or bumper cover?

No. This lip is designed to bolt to the factory bumper using the existing mounting points. Before installation, test-fit the lip to confirm clearance with your OEM bumper cover and hood latch area. Any light interference can be resolved with minor trimming at the attachment tabs.

Should I use adhesive or drill new holes for installation?

This lip uses factory mounting points — no drilling required. Installation is bolt-on using existing holes in your bumper. If factory mounting points are damaged or stripped, you can supplement with adhesive-backed hardware, but the primary method is fastener-based for durability at speed.

Will this stay secure at highway speeds?

Yes, when bolted through factory mounting points using appropriate fasteners. Ensure all bolts are tight before driving. Check hardware periodically for looseness, especially in the first 500 miles. Secure fastening through factory points — not adhesive alone — is essential for stability at speed.
