Description ADRO A23A11-3301 Front Fender for PORSCHE 911 GT3 (992) Refined by ADRO. Balanced as Porsche intended. Built for the newest GT3. Since 1999, the 911 GT3 has followed one formula: naturally aspirated engine, motorsport-derived chassis, no shortcuts. The 992.2 is the latest and sharpest expression of that formula, and one of the last cars built that way. That starting point deserves respect, not a redesign. ADRO's aero program for the 992.2 GT3 was built to honor that. The goal was not to reinvent the car, but to make it faster where it counts: more downforce at minimal drag cost, without disturbing the front-to-rear balance Porsche already tuned in. Every component in this kit contributes to that single objective. Front Fenders A front wheel arch at speed is a pressure trap. Air pumped in by the rotating wheel and fed from the underbody has nowhere to go. That trapped high-pressure air pushes up on the bodywork, generating lift where grip is needed, and chokes the Flow trying to pass under the front splitter. The ADRO front fenders solve both. Upper vents on the guards provide a clean exit path for high-pressure air over the top of the wheel, while pressure-relief exits behind the front wheels bleed the arch into the low-pressure zone along the body side. Venting the arch drops the pressure inside it, cutting front-end lift directly and allowing the splitter and underbody to pull through more Flow, increasing the downforce generated by the whole front end. Air exiting the arch in a controlled way, where the fender directs it, creates less turbulence than air forced out chaotically around the wheel and into the Flow along the side of the car. ADRO also engineered a washer fluid reservoir that sits behind the fender in place of the factory piece, retaining full washer function without fabrication or relocation. - Upper vents on the guards provide a clean exit path for high-pressure air over the top of the wheel. - Pressure-relief exits behind the front wheels bleed the arch into the low-pressure zone along the body side. - Venting the arch cuts front-end lift and allows the splitter and underbody to pull through more Flow. - Includes an ADRO-engineered washer fluid reservoir to retain full washer function.
