The potentiometers on my G27 have had it. I've cleaned them more than once, I've swapped the rarely used clutch with the brake, I've done all the maintenance I can. It's over. (my throttle spikes and won't stay much above an average value of 80% - I'm getting blown away on the straights...) Can anyone help me find new potentiometers that fit and will do the job? Any advice? Logitech have been no help at all. (Some corporate legalese about not encouraging us to open up the pedal housing is all you get). My G27 is a great wheel. It doesn't deserve to become landfill because one easily replaceable four year old part is worn out. Help????
