More spokes for aero and rigidity. That looks great on a road car but not f1.Thunders wrote:Well if Adrian wants do Design Road Cars he better be open for Wheels bigger than 13 Inch. ^^
Regarding aero efficiency I think the deep dish lip of current style rims will not suit the 18" rims.
Looking at WEC cars as reference I think the width of the tire needs to stay if not wider, but the face of the rim will be more flush. Ala brawn 2009 without the rim covers.
