Let the air outta da tires!

Low profile tires is the easiest way,
You have to change all the bulbs to 12 volt,
change the genny and regulator,get a voltage reducer for the heater fan, fuel guage, radio, the starter will run for a while on 12 volts, but there is a different ring gear between 6 and 12 volt starters...
me 2 cents....
