Re: Upgrade or replacing rear end gear ratios

Remember that the overdrive cars had a different ratio rear end so as to improve off the line performance with the overdrive making up for the loss at higher speeds. The non-everdrive rear end was something of a compromise so adding overdrive without changing the rear end will make a huge difference to the top end without changing the off the line at all.
