Hobbs in #10 thoroughly dominated this event. He qualified the McLaren fastest, won both heats, and that yielded 1st overall combined. Posey qualified 2nd, but had an unhappy day.  He DNF'd in  his Surtees after 19 laps in the 1st heat, then finished a well-back 15th (four laps behind Hobbs) in the 2nd heat.
