DeTomaso Mailing List: October 2000, Message #83

Hi Bjorn,
Have you or anyone else here on the forum completed or compared the calc's
to figure out the difference between the added R's between the 3.77 ring
gear and the taller 5th gear???

And how adding BOTH the 3.77 AND the taller 5th gear benefit??? for the sake
of argument everyone use a 4.22 stock U.S. ring gear and a 26" diameter
tire.
Thanks
MD
