    Can't seem to find the definitive answer to this question.

    What is the final drive ratio? I have seen several numbers including one that is split: 2.XX / 4.XX. And what are the 1-6 gear ratios?

    Need to know what to plug in for accurate lap analytics.

    thanks!!!!

    Not sure what it is, but your 2003 R53 has a different final drive than the 2005 & 2006 MCS R53. Hope that helps some.

    I saw that, but it does not list final drive ratios. Need that for Harry's too.

    11.XX is very high for 1st gear. Harry's does not even go that high.

    Anyone who has an R53 Service manual should have them listed?
