Greg Amy: I just read the latest version of the ST Rules for January, 2013. To say the least, I'm confused. Did the STAC and CRB delete the use of rear wing spoilers for STL? I cannot find any reference to the specifications for width(across the trunk), chord depth(front to rear), mount height, etc. Was this an oversight or are rear wings "No Longer Allowed"? I've read the entire ST Regs 3 times and I can't find it. Please define what is the rule for 2013.
