Xtreme Aerodynamics have introduced the follow up to their ubiquitous Twister touring car shell, the Twister Speciale. Developed using the most advanced Computational Fluid Dynamics software to analyse flows and vortex generations, several iterations and a massive track test session lead to an optimal balance, extremely high downforce level and improved aerodynamic efficiency. This resulting body shell gives more corner speed, more rotation along with more top speed.
