Description ADRO A23A11-1301 Rear Diffuser 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 earns its place by contributing to that single objective. - Designed for the Porsche 992.2 GT3 - Increases downforce while adding minimal drag - Maintains the front-to-rear balance tuned by Porsche - Suitable for track days, hillclimbs, and spirited road driving Specifications: - Downforce: Stock 1,145 N; with ADRO Complete Kit 1,389 N; increase of 244 N (approximately 55 lbs) - Drag: Stock 1,071 N; with ADRO Complete Kit 1,083 N; increase of 12 N (approximately 3 lbs)
