During our inspection problems kept coming out with the way we did our bumpers. In result i have two questions:
1) Where can i see a list with the full bumper restrictions? Do any of you have one? I remember searching for one with the height of the ground our bumpers can have, without any luck in the manual, and than having it on the inspectors list.
2) Have the bumper rules ever change since they were first introduced? Is there a possibility that a solution for the bumpers i will find this year be banned by the next?
