[Healeys] Drum Balancing

[Chris Dimmock]

Yes. 
My BJ8 used to jump out of top gear in overdrive top at the end of the main straight at Eastern Creek at 6,000 rpm in overdrive top when I lifted off to turn left. 
My Uncle Pete (my race engineer) told me to get the rear drums balanced. 
It worked. Those heavy, poorly cast suckers put a lot of stress and vibration back through the drive train on over run - on lift off - more than you can imagine.
 Yes. Balance your rear drums. 
Best
