As dictated from the SCCA high command without discussion or details of how the need for smaller restrictors was determined. Is the smaller restrictor necessary - maybe? Couldn't prove it by my lap times but other MC engine cars are very fast but then again so are some Rotax powered cars. I'd just like a little more information than just an edict from Topeka seemingly based on one letter from a member. Maybe I missed the discussion on why the restrictor is necessary.
