Will this diffuser scrape on driveway aprons or steep inclines?

Diffusers sit lower than the stock bumper line. Check your vehicle's approach angle and driveway geometry before installation. If you regularly encounter steep driveways, test fitment or consider protective edge trim to prevent scuffing during low-angle maneuvers.

Does this add exhaust tip clearance, or do I need to modify my setup?

This diffuser expands the rear fascia profile but does not change exhaust tip location. Verify that your current exhaust outlet clears the diffuser's lower vents before final installation. You may need to adjust tip position or angle if there's contact.

Is the 3DS styling purely cosmetic or does it provide functional downforce?

The 3DS design is aesthetic. At street speeds, it adds visual aggression without aerodynamic benefit. Track use would require independent testing and validation — the diffuser is built for appearance first.
