Let me pose the question in another way:

What do the owners and drivers need to present to the audience (race fans) for them to have a successful racing experience (not talking about concessions or facilities)? By experience I mean a desire to come back again.

Does it make any difference to you regarding what kind of wheels I have on the car?

Does it make any difference to you regarding the brand of fuel or oil that I use?

Does it make any difference to you regarding what chassis I'm using?
