Will this scrape on driveways or steep inclines?

The T2 diffuser is designed with minimal extension to the rear bumper line. Verify clearance by checking your vehicle's current rear bumper-to-ground distance and comparing it to the diffuser profile before final installation.

Is this functional or purely cosmetic?

The T2 style is primarily cosmetic, adding visual depth to the rear fascia. It is not engineered for aerodynamic downforce — it's a styling element that suits track and street applications equally.

What prep is required before painting?

Sand and prep the surface per your chosen paint system's guidelines. Wipe down with a tack cloth before application to remove dust and debris.
