Will the diffuser scrape on steep driveways or inclines?

The TD3000 V2 geometry sits close to OEM bumper height. Measure your current ground clearance at the bumper edge before installation. If your vehicle runs lowered suspension, test approach angles on your typical routes — the diffuser extends the aero envelope slightly, so steep ramps may require careful entry angles.

Is this diffuser functional or cosmetic?

It's both. The diffuser channels are shaped to work — they manage rear airflow separation and reduce lift under load. You'll see visual impact immediately; aerodynamic gains are real but subtle on street driving. Track use or higher speeds reveal more benefit.

Does carbon fiber need special care or coating?

Real carbon shows its weave best with a clear protective coat. Most builders apply UV-resistant clear to preserve the finish and protect against oxidation. Sand and prep the surface before applying your chosen finish, then handle normally — carbon is durable and does not require ongoing maintenance beyond regular washing.
