yes rotas would fit. difference bettwen the 15 and 16 is the rotational mass. so if u want then for the strip go with the 15s but for autox get the 16s (assuming ur getting wider width) the 16s would slow u down on the strip but is great with handling (assuming u get AA grade traction tires ) i dont c a difference in the 15 and 16 performance on the strip but then again i am also a noob
