Indycar racing DOES NOT use the multi compound tire strategy maker at the indy 500 or any of its other oval track races. there's a reason for that and that reason would apply to almost all the nascar races.
nascar road races dont need any help. they should add two more as it is and add one to the chase.
add montreal and elkart lake to the cup schedule. drop either of them into sonoma's early summer date and move that race into the chase.
