I was thinking with my money from my taxes I was going to buy some gears. So far I have two in mind. 3:73s and 4:10s. I have a list of the positive and the negative but I wanted to hear it from the mouths, or in this case words, of others. One question I still have is what are the RPMs at 60 MPH, 70 MPH, and 80 MPH on either of those gears? Since I'll mostly be going those speeds. Any other input will be appreciated as well.
