: A 91 850 I 6 speed has a 2.65 rear axil ratio. This is not the best for acceleration, and I will not be driving over 150. Has anyone had experiance changing rear axil ratios. USED diff's are about $600, while gear sets from Korman and Dinan are about $3000. Can the differential from an auto transmission be used in the 6 speed. Any help will be welcome.


On the same line, what effect will changing the ratio have on an 850's various systems? I would hazard a foolish guess that to make the speedometer read correctly isn't a matter of changing a $2 plastic gear.
