When manufacturers presented their designs to the Iconic committee in 2010, Lola proposed two different aero-kits, each with equal aerodynamic performance and which would give a visual diversity for both Chevy and Honda.

As we know, IndyCar introduced aero-kits in 2015, primarily to give Chevy and Honda that visual diversity. However, they haven't been without their issues but the aero-kits have produced a definite difference, between both Chevy and Honda.
I love the look of the universal body kit but I think IndyCar should seriously consider something, on the lines of Lola's concept as during testing.
