I need to get an interpretation of the rule on door nets and leg restraints. The car will run in B Competition Coupe and it will exceed 175 MPH. We currently use arm restraints. Can we use leg restraints in place of the full door net? We are tired and we are having trouble with the door net and with reading and understanding the rule. It can be read to mean that leg restraints can be used in place of the full door net. I sure need a little help on this one. Thanks in advance.
