I have to wonder out of the guys that have cockpit adjustable shocks how many can actually make improvements while they are racing as opposed to guys that are making their cars worse out on the track. I don't think the shocks are a problem, nor to I think there is a domination problem.
Just a few seasons ago the goat won every national 450 mx moto two years in a row. Thats 48 motos, 48 races that one guy won. I would have to think that is a almost impossible feat, how does one guy have the talent to do that plus the luck of 39 other guys not crashing him in 48 races. Thats domination, thats not happening in sprintcars.
