I don't think 'changed' is a good word...... But I'll say that we have made a lot of 'improvements.'
We have improved our suction, by adding another cup.
We changed the design of our ramps at Chesapeake, but over the course we have improved it and will be adding on to the improvement (new wood pieces, brackets etc etc) at the Championship.
Good Luck Teams, and if you need any kind of help........
ANY KIND OF HELP....you guys are always welcome at 612's pit.
