Hey as a European sporadically watching indycar I always wondered why certain teams are "always" dominant and others not. Because how I understand it the chassis is all delara and only Chevrolet and honda as engine suppliers. What makes then the penske team for example being such a prominent top team? Is it just like F1 pure a money thing? Because like there is only so much you can do with suspension and is relatively easy to copy no?

Would love to understand that a bit more.

Thansk in advance for the replies
