Forged with 3000 tons of pressure using heat-treated 6061 aluminum alloy. The resulting high-density aluminum structure allows them to be 27% lighter than cast wheels of the same size ringing in a paltry 21lbs per wheel. The backpad of the wheel is specifically cut to reduce even more weight while maintaining strength. Lightweight wheels reduce unsprung weight on each corner of the vehicle compared to the equivalent cast wheel, improving vehicle performance and maneuverability, reducing braking distances and faster acceleration. The perfect wheel whether you’re driving on a city street or bouncing off the curbs at your local race track.Size: 19x9"
