The optional ACR Extreme Aero Package adds an adjustable, dual - element, carbon fiber, 73.9 - inch rear wing (a 69.9 - inch rear wing is standard), rear carbon - fiber diffuser, detachable front - splitter extender,
additional dive planes and removable louvers to relieve front air pressure.
Other alterations include fully exposed carbonfibre for the roof and
additional panels, as well as improved aerodynamics from a modified rear wing, a front splitter and
dive planes that, Lanzante claims, increase downforce over the P1 GTR by 40 %.
