I have a new 09 M8 has anyone done a gearing change and or are there gears available yet for the electronic reverse DD? If so how low can you gear down to and not go into overdrive, or be at a 1 to 1 drive clutch to driven clutch ratio. I understand that the DD driven clutch is a smaller diameter than other brands and will go into overdrive quicker. Any info on this would be helpfull to me as I know nothing about the Cat clutching as I have preveously owned Polaris 800's.
