The wing packages are closely regulated by the IRL, and as a result wings of a given type from each make all look very similar. To this writer, the Infiniti seems to have a more throaty exhaust note, with a bit more bass than the Aurora. To keep costs down, the IRL does not allow teams unlimited leeway in what equipment they can run. There are three primary categories where teams have choices to make about which brand to buy. The first letter indicates the chassis choice, the second the engine, and the third the make of tires.
Tires are the same as current.
