I just don't understand how it's a evolution to go to something that has already failed. And from what I understand it failed because of cost.

Dad your right mini sprints did go down years ago and have made a come back the biggest reason for that is because of cost. Mini sprints are running lap times close to that of midgets and sometime faster for a fraction of the cost. That has lead guys from midgets and sprint cars that don't have the big bucks to compete at those levels to move to mini's and compete with the budget they do have.

Now that we are talking cost, Dad and Cadpro have Midgets that were converted into minis so it's easy to make the switch. What about the guys that have mini's? Now they would have to get new cars cost, cost, cost.

RickyBobby (if that is your real name) is right you let this in then what can someone run a esslinger and say "well it only has 150 hp"?
