Will this diffuser scrape on steep driveways or inclines?

The GT Tune profile extends beyond the factory bumper line. Verify clearance by comparing the diffuser height to your current driveway approach angle and any speed bumps on your route. If ground clearance is tight, adjust driving lines accordingly or consider your vehicle's current ride height before committing.

Does this diffuser provide real downforce or is it cosmetic?

This is a styling piece designed to match the GT Tune aesthetic. Any aerodynamic effect at street speeds is minimal. It's built for the look—if you're chasing measurable downforce, that requires full-platform aero tuning with engineered components.

What prep work do I need before painting?

Sand and prep the surface with standard finishing techniques before applying your chosen paint system. Follow your paint supplier's prep guidelines for adhesion and durability—this ensures the finish bonds properly to the FRP base.
