Title: LSD Ratios
Post by: Dazzler on 13 April 2008, 20:18:59

Do all V6's have the same final drive ratio???

Are the manual and auto ratios different???

Will an LSD fit on any V6???

It won't. Your speedo takes its reference from the ABS.  :y

Its unlikely to be noticeably different if it all.

The speedo is unaffected as the speed pulse comes from the ABS sensors after the diff.....so its ratio exclusive!
