Question On overdriving rear wheels
hey all...new to the forum. i have a quick question on overdriving my rear wheels. my hpi sprint is belt driven with 32T diff case gears and 15T pulleys. I know this is a super nooB question, but if i wanted to overdrive my rear, would I go up or down teeth on my rear pulley? I understand I would have to go down or up the same amount respectively on my diff in order to keep good belt tension. OR...would it be easier to UNDERDRIVE my front wheels?
