Will this scrape on driveway approaches or steep inclines?

The S-Line diffuser sits at the factory rear bumper height and adds minimal extension below the stock line. Verify your current suspension ride height and test approach angles before installation—if your vehicle already scrapes the factory bumper, the diffuser will scrape at the same points.

Does this require drilling into the rear bumper?

No. This diffuser is engineered to mount using factory attachment points on the OEM bumper structure. Confirm your bumper's fastener locations and hardware before ordering to ensure alignment with this panel's mounting tabs.

Is this purely cosmetic or does it add downforce?

This is an S-Line style piece designed to match factory performance aesthetics. The vane profile follows OEM styling; actual aerodynamic benefit depends on vehicle speed, suspension geometry, and flow dynamics. Install it for the look—performance gains are minimal at street speeds.
