ok you can believe what you want. I just don't understand why we care about the cost. we don't pay for it. Justin Marks will tell you different on the cost. also the can put them together with " clenched fist" all they want but if the teams were making the parts they would cost double to triple the price.
Also this is NASCAR show. it is NASCAR cup series not team "what ever" series. Nascar mandates the rules no different than IMCA, USRA, NHRA, IRL, F1 or any of the other Sanctioning body that exist. So yes its their rules. its the same in Xfinity and Truck. Those 2 can't just do what they want. they have to do what's in the rules. If the teams don't want to put together these "kit cars" they don't have to. the can go be part of a different series. Most teams were upset when they pushed the roll out of the new car back a year because they had set their budgets for the next year and had to redo them because it cost more to run the old car. I heard that from live interviews from several executives from different teams ( RCR,JGR, Hendrick). Every part that they used to produce for the old car had to be approved. So give me a break that NASCAR just now is calling the shots. Apparently there are things that the teams can do. Most of the steering issues at Bristol were on toyotas. most of the tire issues were on fords. yes there were some others but they weren't the majority.
