hwellens Posted May 7, 2008 Share Posted May 7, 2008 I think you want a lower ratio rear to go faster at the same engine speed. Depends on the body style you have. The lower ratio rears came in the coupes (3.70) the others were higher (4.12). Basicaly about a 10% difference. Link to comment Share on other sites More sharing options...
