Is it possible to make high performance carbon fiber wheels? Christian von Koenigsegg explains that it’s possible and his company has been doing it for a few years now… His creation – the carbon fiber composites wheels are lightweight and extremely strong. These carbon fiber wheels weigh 40% less than a comparable forged aluminum wheel. The carbon fiber wheels increase performance by reducing unsprung weight and rotational mass, and the only non-carbon fiber part is the tiny air valve.
