From the 2009 SCTA rulebook, I find the following description of partial streamlining for an A class partially streamlined tailpiece: Regarding the so-called seat/tail section "no part of the seat/tail section may be closer than 4" from the ground..." The question is, where does the 4" measurement start? My belly pan is only 1-1/2" inches from the ground, and we would like to make this continue to the back of the seat/tail section, but where must it be 4" from the ground? At the rear extremity, or at the rear axle, or where?
