Have you guys noticed that the super high end GT3 cars and Hypercar's all have metal center caps that stay on the car during the race? Vs. the new Sports Car Challenge cars that just have no center caps. I'm sure most of this is due to a single center spindle on the GT3 vs. 5 lugs on Sports Car.. but is there something else? I'd like to get metal caps if it means i can leave them on.
